Introduction to Field Terminations

Overview

This chapter introduces the Triconex external field termination products for the Tricon system.All cables and termination panels are built to withstand harsh industrial environments. The environmental specifications for components used on these products are the same as for a Tricon chassis. For more information, see the Planning and Installation Guide for Tricon v9–v10 Systems.

External Termination Panels

An external termination panel (ETP) is an electrically passive printed circuit board (PCB) to which field wiring is easily attached. A panel connector, terminal blocks, and optional components are mounted to the PCB and enclosed in a DIN-rail compatible plastic housing. A termination panel and associated cable pass input signals from the field directly to an inputmodule, or pass output signals from an output module directly to field wiring. Thisarrangement permits the removal or replacement of I/O modules without disturbing field wiring.
Standard termination panels are best for remote marshaling of field wiring where maximum.
flexibility, high density, and simple maintenance are desired. Standard termination panels allow you to marshal field signals in a separate enclosure up to 99 feet (30 meters) from a Tricon.
A standard termination panel consists of a PCB with all necessary components—such as two-piece terminal blocks, resistors, fuses, and blown-fuse indicators—mounted on a DIN-rail compatible plastic housing. The housing snaps into mounting rails in accordance with DIN 50 22.
Compression terminals on the standard panel are designed for use with 24- to 12-gauge (0.3mm2to 2.1 mm²) and have a fuse with a blown-fuse indicator to protect the field wiring and field device. Standard termination panels are pre-configured for a specific application. For instance, commoned standard termination panels can be ordered with commoned power-and-return, or redundant DC power configurations with a diode-ORing. The thermocouple input termination panel provides cold-junction temperature sensors and can be ordered with upscale, downscale, or programmable burnout detection. A standard termination panel for analog voltage inputs provides commoned or non-commoned signal returns, while the current-mode version has a precision resistor at each input point to convert current to voltage.
Each standard termination panel is packaged with a matched interface cable that connects the panel to the backplane of a Tricon chassis. A female connector at one end of the cable is keyed to match the male connector on the Tricon backplane. A male connector on the other end of the cable attaches to the standard termination panel.
In addition to standard termination panels, there are other types of termination panels,
including:
• Basic termination panels
• Hazardous location (nonincendive) termination panels
• RG 1.180 Termination Panels
• Termination panels with interposing relays
• Bypass panels for digital inputs
• Termination panels with RTD/TC/AI input signal conditioning
• Termination panels for 3603B digital output modules
• Termination panels for 3806E analog output modules

Basic Termination Panels

Basic termination panels are a low-cost means of connecting field wiring to a Tricon. Basic termination panels allow you to marshal field signals in a separate enclosure up to 99 feet (30
meters) from a Tricon chassis. A basic termination panel consists of a PCB—with panel connector and terminal blocks—mounted on a DIN rail-compatible plastic housing. The housing snaps onto mounting rails inaccordance with DIN 50 022. Current-to-voltage conversion resistors are also mounted on analog input panels configured for current input. You must provide any other components
required for your application.
The panel connector and terminal blocks are directly interconnected via the PCB. The compression terminals on the terminal blocks are designed for use with 24- to 12-gauge wiring.A basic termination panel is packaged with a cable that connects between a Tricon chassis.backplane and the basic termination panel. A female connector on one end of the cable is keyed. to match the male connector on the Tricon backplane. A male connector on the opposite end of the cable is keyed to match the male connector on the termination panel.
Basic termination panels are available in these configurations:
• Digital input panels
• Digital output panels
• Relay output panels
• Analog input panels
• Analog output panels
• Pulse input panels
• Pulse totalizer input panels

Termination Panels with Interposing Relays

Termination panels with interposing relays can be used with most digital output modules and
are recommended for these applications:
• Load currents greater than 2 amps
• Field voltages greater than 115 VAC
• Voltage-level conversions
• Motor-starter circuit compatibility
Interposing relay panels are available in these configurations:
• 16-point commoned
• 16-point non-commoned
The digital outputs of the interposing relays are not fault-tolerant. However, each relay provides an auxiliary contact that can be fed into a digital input to send a loopback signal to the control program. A user-written loopback check in the control program can ensure that the relay has achieved its commanded state. The loopback cable must be ordered separately.
Each interposing relay panel consists of:
• A 7 in x 19 in (36 cm x 48 cm) rack-mountable panel with terminals for 16 digital outputs and 16 digital inputs.
• Two ELCO connectors mounted on the panel for connecting to digital input modules using digital input cables 9141-010, 9142-010, or 9143-010.
• An EIA standard RS-310-C plate on which the termination panel is mounted.
• A digital output module and a cable compatible with the selected coil voltage.

Bypass Panel for Digital Inputs

Bypass termination panels can be used to connect digital inputs using a bank of 32 pre-wired switches. Bypass panels have a master keyswitch and terminals for redundant +24 VDC power.
sources. Each input point contains an ON status indicator and can be energized only if the master keyswitch is ON and the corresponding point switch is ON. Each point has a location for
a user-definable label.
Each bypass termination panel comes with one or two 10-foot (3-meter) cables for connecting.the termination panel to a Tricon backplane.

Termination Panel with RTD/TC/AI Input Signal Conditioning

Termination panels which use industry-standard analog signal conditioners provide a flexible, user-configurable interface to resistive thermal devices (RTDs), thermocouples, and 4-20 mA
transmitters. Each termination panel supports 16 points, and each analog module can support up to 2 panels. These termination panels are compatible with any signal conditioners in the 1 to
5-volt output range. For example, the 7B series of signal conditioners from Analog Devices™ areknown to work well.

Termination Panel 9251-210 for Digital Output Module 3603B

The special 16-point non-commoned digital output termination panel 9251-210 is required for use with the 16-point non-commoned digital output module 3603B.

Termination Panel 9863-710 for Analog Output Module 3806E

The special analog output termination panel 9863-710, with buffered loopback signals, isavailable for use with the high-current analog output module 3806E

Cables

Three types of cables can be used with the Tricon:
•Interface Cables
•Fanned-Out Cables
•Special Cables (Relay Loopback)
Interface Cables
Interface cables are packaged with all termination panels. Each interface cable has a female connector on one end for connection to the male connector on a Tricon chassis backplane. The
opposite end has a keyed male connector for connection to a termination panel. Although the standard length of all interface cables is 10 feet (3 meters), you may order any.
length cable up to 90 feet (27.4 meters) in 10-foot increments using the last two digits of the termination panel's model number to specify length in feet. For example, specify 9xxx-x50 if you
want a 50-foot (15-meter) cable instead of the standard 10-foot (3-meter) cable Fanned-Out Cables Fanned-out cables are a lower-cost alternative to using external termination panels. Fanned-out
cables allow you to marshal field signals in a separate enclosure up to 99 feet (30 meters) froma Tricon. One end of a fanned-out cable has a female connector that connects to a Tricon chassis.
backplane. The other end of the cable contains 50 fanned-out leads, each individually labeled.with its corresponding connector PIN.
Each fanned-out cable has the following characteristics:
• PVC outer covering
• 56-pin connector at one end
• 50 stranded, stripped, tinned, and labeled 22-gauge leads at the opposite end
Fanned-out cables should only be used with digital input and digital output modules. They are not certified for use with analog signals. Contact the Triconex Customer Support Center if you
need a fanned-out cable for handling analog signals. Although the normal length of all fanned-out cables is 10 feet (3 meters), any length cable can be ordered up to 99 feet (30 meters) in 1-foot increments, using the last two digits of the cable model number to specify the length in feet. For example, the model number 9101-050 specifies a 50-foot cable instead of the normal 10-foot cable.
Special Cables (Relay Loopback)If your application requires a special cable, it must be ordered separately. For example, if you want to verify relay activation on a relay termination panel using a digital output module, you must order a relay loopback cable to connect between the relay termination panel and a digital input module. Currently, the only special cable available is the relay loopback cable (914x-010).
