The Emerson +5X00226G01 module is indeed an Emerson Ovation™I/O interface module for the Distributed Control system (DCS) and Programmable logic controller (PLC) capabilities of Ovation™ systems.

Product Description:

The module acts as a bridge between the Ovation™ control system and various field devices:

Received signals: These signals can be analog signals (e.g., temperature, pressure), digital signals (e.g., on/off status), or special signals depending on a particular module type.
Send control signals: According to program logic and system commands, send control signals to actuators or other devices.
Management communication: The use of standard industry communication protocols facilitates smooth communication between the control system and field equipment.
Product parameters and specifications:

Number of I/O channels: Usually between 8 and 32 channels, depending on the configuration.
Power supply voltage: 24vdc or 48vdc can be used depending on the module.
