Basic Information

Manufacturer: Emerson (formerly Westinghouse Electric)

Origin: United States

Installation Method: Ovation standard chassis backplane installation, supporting hot swapping

Compatible Systems: Ovation DCS full series controllers (OCR1100/OMC100, etc.)

Status: Active mainstream DCS I/O cards, commonly used in power plants / industrial process control Function positioning

32-channel DC digital output, used to convert the control system digital signals into 24VDC drive signals to control on-site actuators such as relays, contactors, and solenoid valves

It adopts current source output (Sourcing), directly outputting +24VDC to the load

It has overcurrent, short circuit, and undervoltage protection functions and fault diagnosis capabilities, uploading the status to the system in real time

Channels are independently isolated, with strong anti-interference ability, suitable for industrial harsh environments

Supports online diagnosis and hot replacement, without the need for downtime maintenance
