1C31219G01 digital output module

1C31219G01 is a digital output module developed by Westinghouse (now integrated into 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, enabling reliable control of field actuators such as relays, solenoid valves, and indicator lights in harsh industrial processes. Below is its detailed information:

1. Core Technical Specifications

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