Product Overview
The GE IC694MDL930CA PACSystems RX3i Discrete Relay Output Module is a digital relay output module used in GE PACSystems RX3i PLC systems for controlling external electrical devices. It provides the interface between PLC control logic and field-level actuators by switching output circuits according to commands from the RX3i CPU.
As a relay output module, the IC694MDL930CA uses relay contacts to control connected loads, making it suitable for applications where electrical isolation and flexible load switching are required. It can be used for controlling devices such as contactors, solenoid valves, indicator lamps, motor control components, and other industrial equipment.
Unlike transistor output modules that are typically optimized for high-speed switching, relay output modules are commonly selected for applications requiring contact-based switching compatibility with different voltage and current types.
The module integrates into the PACSystems RX3i modular architecture and works together with CPUs, input modules, communication modules, power supplies, and field devices to build complete industrial automation systems.

Working Principle
The IC694MDL930CA operates by receiving output commands from the PACSystems RX3i CPU and switching relay contacts to control external devices.
A simplified control path is:
PLC Program → RX3i CPU → Relay Output Module → Field Actuator
When the PLC program determines that an output action is required, the CPU sends a command to the relay output module. The module activates the corresponding relay contact, allowing electrical power to be switched to the connected field device.
The relay contacts provide electrical separation between the PLC control side and the external load circuit, allowing the module to interface with various industrial devices.
This operating method makes relay output modules suitable for applications where flexible switching and load compatibility are important.
