1C31122G01 digital output module

The 1C31122G01 is a digital output module developed by Westinghouse (now part of Emerson Automation Solutions) for its Ovation Distributed Control System (DCS). It is designed to convert digital control signals from the DCS into discrete output signals to drive field devices such as relays, solenoid valves, and indicator lights, ensuring reliable control of industrial processes. Below is its detailed information:

1. Core Technical Specifications

Parameter	Details
Output Channels	16 independent independent independent discrete output channels, divided into 4 isolation groups (4 channels per group) to minimize cross-interference.
Supported Output Signals	DC voltage signals: 24V DC (typical), with configurable "on" (≥18V DC) and "off" (≤5V DC) thresholds. Compatible with driving external relays, solenoid valves, and other low-power industrial actuators.
Load Capacity	Maximum continuous current per channel: 2A; peak current (short-duration): 5A, suitable for most industrial on-site devices.
Response Time	≤10ms (from digital command to output state change), ensuring timely execution of control actions in fast-response processes.
Power Supply	24V DC ±10% (power consumption ≤6W), fully compatible with Ovation DCS rack power modules (e.g., 1C31234G01).
Isolation Rating	Group-to-group isolation: ≥600V AC (1 minute); Module-to-backplane isolation: ≥2500V AC (1 minute), effectively preventing ground loops and electromagnetic interference (EMI) in industrial environments.
