Triconex 97717400195-210 3000656-210 An external termination panel (ETP)
An external termination panel (ETP) is an electrically passive printed circuit board (PCB) to which field wiring is easily attached. The PCB mounts panel connectors, terminal blocks, and optional components, all enclosed in a DIN-rail-compatible plastic housing. A termination panel and associated cable pass input signals from the field directly to an input module, or pass output signals from an output module directly to field wiring.

This arrangement allows you to remove or replace 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
