GE IC800SSI228RD2-CE – SSI Encoder Interface Module for Industrial Automation

The GE IC800SSI228RD2-CE is a specialized industrial automation interface module developed by General Electric for motion-control and position-feedback applications.
It is typically used within GE VersaMax or related GE automation architectures to connect SSI (Synchronous Serial Interface) absolute encoders to PLC or PAC controllers.

The module enables high-speed acquisition of position data from rotary or linear encoders and converts it into usable digital information for control systems. This makes it essential for applications that require precise motion feedback, such as robotics, CNC machinery, and automated production systems.
