The GE IC670MDL930 Field Control Discrete Output Module is a discrete output module used in distributed industrial automation systems to transfer control commands from the control system to discrete field devices.
In practical automation equipment, many final-control actions are binary: a valve is commanded open or closed, a relay is energized or released, a solenoid is activated, or an auxiliary control circuit is switched. The IC670MDL930 sits between this control logic and the field wiring, handling the discrete output side of the I/O system.
The module belongs to the GE Field Control family and is intended for modular I/O installations where field devices are separated from the main controller. This type of arrangement is common in machine-control cabinets, process equipment, material-handling systems, and distributed production lines.
For troubleshooting, the module should be considered as one section of the complete output path. A failure at the controller, communication network, output channel, field wiring, or connected actuator can produce similar symptoms, so checking the entire circuit is often more effective than replacing the I/O module immediately.

The IC670MDL930 is intended for applications requiring discrete output commands within a Field Control installation.
Key characteristics include:
The connected load and electrical characteristics should be checked against the actual system requirements before commissioning or replacement.
The operating path can be viewed in practical terms as:
Controller → Field Control Network → IC670MDL930 → Output Circuit → Field Device
The controller generates an ON or OFF command according to the programmed machine or process sequence. That command is transferred through the Field Control architecture to the appropriate output channel.
The IC670MDL930 then controls the corresponding discrete output circuit. The field device responds to that output state, allowing the controller to perform actions such as energizing a relay, operating a solenoid, or enabling another control circuit.
In a production machine, for example, one output may command an actuator while separate input modules monitor the actuator’s position or operating status. This separation between command and feedback makes it possible for the control program to verify whether the commanded action has actually occurred.
The IC670MDL930 can be used where industrial equipment requires discrete control signals from a distributed I/O system.
| Application | Typical Use |
|---|---|
| Packaging Machinery | Solenoid and actuator commands |
| Material Handling | Conveyor and equipment control |
| Assembly Equipment | Pneumatic and electrical actuator control |
| Machine Tools | Discrete machine functions |
| Process Equipment | Valve and auxiliary-device control |
| Motor Control Systems | Relay and control-circuit switching |
| Production Lines | Sequence-related outputs |
| Industrial Control Panels | Distributed discrete output |
Its practical application depends on the connected field devices and the electrical requirements of the complete control circuit.
The IC670MDL930 normally works together with several components within a Field Control installation.
| Component | Function |
|---|---|
| IC670MDL930 | Sends discrete output commands |
| Field Control I/O Station | Provides the distributed I/O structure |
| Controller | Executes machine or process logic |
| Solenoid Valve | Converts electrical output into mechanical action |
| Interposing Relay | Provides electrical isolation or load interface |
| Contactor | Switches applicable equipment circuits |
| Discrete Input Module | Provides feedback from field devices |
| Field Wiring | Connects the output channels to loads |
| Communication Network | Transfers I/O information between system components |
The output module should be evaluated together with the connected load, field wiring, I/O station, and controller configuration.
Before replacing the IC670MDL930, identify which field devices are connected to the affected output channels. This is especially important in control cabinets where several outputs may operate similar valves, relays, or actuators.
Recommended checks include:
If a field device remains inactive despite an output command, first determine whether the command reaches the module. The next checks should include the output circuit, wiring, external power, and field device itself.
For the IC670MDL930, related equipment should be selected according to the required Field Control function and the characteristics of the connected field devices.

When selecting a replacement for the IC670MDL930, verify the output function, connected load, Field Control architecture, wiring, and controller configuration. A similar physical form does not by itself establish electrical or system compatibility.
The module is used for discrete output functions in a Field Control system. Depending on the application, its outputs can be associated with compatible actuators, relays, solenoid circuits, or other discrete control devices.
Start by confirming that the controller is issuing the expected command. Then check the Field Control communication path, output-channel status, wiring, field power, and connected load. This approach helps separate a control-system problem from a field-side fault.
A field device with an incorrect electrical requirement, damaged wiring, or a shorted load can create symptoms that resemble an I/O failure. Confirming the load and output circuit first can prevent unnecessary module replacement.
No. The replacement must match the required Field Control architecture and output function. The connected load, wiring arrangement, system configuration, and other I/O requirements also need to be compatible.
