Modular and flexible construction
Reduced installation time and expense
Easy online expansion
Field-mounted capable hardware
1:1 Redundancy for traditional I/O

Plug-and-Play I/O

Introduction
S-series traditional I/O interfaces offer easier installation while retaining the proven features of M-series I/O interfaces. This modular I/O subsystem offers flexibility during installation and is designed for extreme environmental conditions of field installations. S-series traditional I/O is equipped with a snap-in retention system for quick installation. The I/O interfaces can be installed in any of the possible 64 slots.
All wiring is through the carriers and terminal blocks so that modules can easily be removed without disconnecting any wires. Modularity, fast installation, online expansion, and environmentally robust hardware make DeltaV™ S-series traditional I/O a smart choice for your process control system.
Benefits
Modular and Flexible Construction: The S-series traditional I/O subsystem is designed with your investment in mind. Each controller supports up to eight I/O carriers that form a robust, passive bus for up to 64 I/O interfaces. Each interface has a matching I/O terminal block and can be installed in any I/O slot on the bus. Carriers and interfaces can be added online, without interruption to the existing I/O communication.
This modular design enables you to purchase the exact amount of I/O cards, eight-wide carriers, power/controllers, and two-wide carriers you need and add more DeltaV I/O as your system grows.
DeltaV S-series Traditional I/O
Reduced Installation Time and Expense: The DeltaV system’s S-series I/O interfaces are designed for quick assembly and error-proof maintenance. All carriers snap onto T-DIN rails and interfaces snap into the I/O slots without the use of any tools.
Each I/O interface has a separate wiring terminal block, which connects field wiring to the interface. The I/O card can easily be removed without touching the I/O wiring on the terminal block. Some I/O cards can also use the fused terminal block, which is equipped with in-line fuses that can be pulled to isolate power to the field circuit.
Traditional I/O interfaces have I/O function keys that allow the terminal block to be set to receive a specific I/O card. These keys ensure that the correct I/O card is always plugged into the corresponding terminal block. The keys provide a safety measure by preventing the wrong I/O card from being installed. It’s incredibly easy to use and gives you time to do more.
Field-mounted Capable Hardware: All S-series traditional I/O interfaces are rated for extreme operating temperature ranges of -40 to 70°C (-40 to 158°F). The interfaces can be installed in field-mounted enclosures, so you can significantly reduce the footprint of your equipment and increase valuable control room space for other uses. This also allows you to save on wiring expenses by eliminating the need for long runs of multi-cores. The integrated design of the I/O subsystem can eliminate the need for marshaling panels. This saves you even more in your total capital costs.
1:1 Redundancy for Traditional I/O Cards: Increased system availability is easy with S-series traditional I/O cards. Four traditional I/O card types are available with redundant terminal blocks for critical field circuits. Simply install a pair of cards on the prescribed redundant terminal block, and the DeltaV Distributed Control System (DCS) will automatically recognize them as a redundant pair. There is no configuration other than auto-sensing the redundant pair.
Plug-and-play I/O: All S-series traditional I/O components plug into the I/O interface carrier and are auto-sensed by the controller. There are no addressing switches or jumpers. Cards can be installed in any order, simplifying the I/O subsystem design. New I/O interfaces are detected by the system and added to the engineering database automatically. Additional features can be enabled as needed and downloaded without disruption to existing I/O communication, allowing you to install the I/O you need today with the ability to expand tomorrow.

The I/O cards are connected to the field with a terminal block, which allows removal of I/O cards without disconnecting any field wiring.
I/O Cards
A variety of analog and discrete I/O interfaces are available to meet your specific requirements. The following cards support simplex or redundant installation:
AI 4-20 mA HART, eight channels
AO 4-20 mA HART, eight channels
DI Dry Contact, eight channels
DO 24V DC High Side, 8channels
AI (Plus) 4-20 mA HART, 16channels
AO (Plus) 4-20 mA HART, 16channels
DI (Plus) 24V DC, Dry Contact, 32channels
DO (Plus) 24V DC, High-Side, 32channels
The following I/O cards are supported in simplex format to meet your field wiring needs:
RTD, eight channels
Thermocouple, eight channels
Millivolt, eight channels
DI 24V DC Isolated, eight channels
Pulse Count Input, four channels (Isolated DI)
Sequence of Event, 16 channels (DI 24V DC)
DI 120V AC Low Side Detection, eight channels
DI 120V AC Isolated, eight channels
DO 24V DC Isolated, eight channels
DO 120/230V AC High Side, eight channels
DO 120/230 Isolated, eight channels
All I/O cards are enclosed in a common form factor that plugs into the I/O interface carrier. The housing is clearly labeled with the enclosed I/O card type. All cards have power and internal error indicators. Eight-channel cards have clearly visible channel status LEDs.
All cards meet ISA G3 corrosion specifications by the careful selection of superior electronic components and the use of conformal coating.
Pulse Counters are available on most DI cards. The supported maximum frequency varies from 0.1 Hz on AC signals to 75 or 120 Hz on 24V DC inputs, and up to 50 kHz on the High-speed Pulse input card.
DeltaV DCS provides control module-level time stamping for log events and alarms. For greater event resolution, the 16-channel Sequence of Event DI card can provide signal-driven events to a resolution of +/- 0.25 ms per card, or within 1 ms per controller. Please refer to the Sequence of Events PDS for more information on Sequence-of-event data collection and system options for this feature.
I/O Card Redundancy
Redundant I/O cards are available for critical applications. The same card can be used in simplex or redundant applications. When installed on a two-wide redundant terminal block, the cards are recognized as a redundant pair by the controller. The controller scans each card and determines which card is acting as the active interface. When a fault is detected, the system automatically switches to the standby I/O card.
DeltaV control modules reference simplex and redundant I/O channels identically, and there is no special configuration required to take advantage of redundancy.
Switchover of a redundant I/O card is completed within two scans of the I/O bus. Make-before-break contacts ensure digital field instruments remain powered and the process is undisturbed. Analog output signals are briefly driven by both cards for <5 ms during switchover of the card.
DeltaV S-series Traditional I/O
Hardware alerts automatically report hardware integrity errors for both the primary and secondary cards. Any event that causes a switchover is also reported automatically through the system hardware alerts and is logged in the Event Chronicle.
Events that can cause a switchover include:
Hardware failure within the active card.
Communications failure between the active card and the controller.
Detection of a fault in the field wiring.
A switchover may also be initiated from the diagnostics explorer, and the health and status of both cards and their channels are available in the diagnostics explorer.
The system automatically commissions a new standby card. In safe areas, failed cards can be replaced under power.
In hazardous areas, appropriate installation procedures must be followed.
I/O Terminal Blocks
A variety of I/O terminal blocks are available to meet specific functionality and environmental requirements of the installation. The I/O interface is a combination of the I/O card and the I/O terminal block. Each I/O interface is uniquely keyed so that once installed in a carrier slot with a terminal block, that terminal block will only accept a like replacement card.
The keying mechanism consists of two keying posts that rotate and lock into the terminal block base. Each post has six positions: A-F and 1-6. Each card is assigned a unique key, which is marked on the side of the I/O card:
The keys prevent installation of an incorrect card, and the graphical information on the card makes it easy to determine if a keyed slot will accept a particular card.
There are nine different simplex I/O terminal blocks available to meet the wiring needs of field signals.
8-channel terminal block
Fused 8-channel terminal block
AI 8-channel terminal block
AI 16-channel terminal block
AO 16-channel terminal block
