Overview
The Emerson 1C31233G04 is a compact, high-performance Sequence of Events (SOE) contact input module designed for the Emerson Ovation distributed control system. This EMOD assembly provides 16-channel sequence of events input with contact input capability, offering precise event tracking and data logging for industrial process control and monitoring applications.
Key Features
- 16 SOE input contact channels with input voltage range of 12 to 24 VDC
- Plug-in component with built-in fault tolerance and diagnostics
- 48V onboard wetting supply for reliable contact input sensing
- Enables accurate recording of sequential events essential for monitoring system performance, diagnostics, and troubleshooting with high-speed input processing to capture critical events with minimal latency
- I/O module that communicates on the I/O bus to the Ovation Controller and provides an interface between the controller and plant processes
