The GE IC694MDR390 is a PACSystems RX3i mixed I/O module that integrates both digital inputs and relay outputs in a single compact unit. It is designed to simplify field wiring and reduce rack space requirements in industrial automation systems.
This module combines 8 discrete 24V DC inputs and 8 relay outputs, making it highly efficient for applications that require both signal monitoring and direct load control. It is widely used in manufacturing systems, process automation, and machine control environments where flexibility and reliability are essential.
By merging input and output functions into one module, the IC694MDR390 reduces system complexity while maintaining strong electrical isolation and industrial-grade durability.
