GE IC670MDL330J

At a Glance

The GE Fanuc IC670MDL330J belongs to the GE Fanuc Field Control family and provides a compact interface between control-system output data and AC field loads. It is a 16-point discrete output module with a 12–120 VAC rating.

Rather than acting as a standalone PLC, the module works within a distributed I/O station. The Bus Interface Unit handles the system-side data processing, while the output module performs the corresponding field switching.

Electrical Performance

The module is designed for AC loads from 12 to 120 VAC. Its specified output range extends from 10 to 132 VAC at 47–63 Hz. Each output can handle up to 1 A, but the total module load is limited to 4 A under the specified derating conditions.

Other published characteristics include a maximum 10 A inrush current for one 20 ms cycle, a maximum 2 V output voltage drop, and a minimum 10 mA load current per point. The ON and OFF response time is less than one-half cycle.

Functional Design

The IC670MDL330J contains one group of 16 discrete outputs. Each output has a corresponding logic-side LED, allowing technicians to observe output status directly from the module.

The module itself receives operating power through the Field Control BIU. Connected AC loads require an external field power source. This separation is an important part of the installation design.

A group fuse and protective circuitry help protect the output section. The Series J product listing also identifies a 5 A slow-blow group fuse and individual RC snubber circuits.

Where It Is Used

This GE Fanuc output module is suited to systems that require multiple discrete AC switching points. Depending on the machine design, outputs can interface with devices such as:

• Contactors
• Relays
• Solenoids
• Indicator lamps
• AC actuators
• Other compatible field loads

The connected equipment must remain within the module's electrical and load limitations.

Replacement Checklist

When replacing an IC670MDL330J, maintenance personnel should verify:

1. The complete IC670MDL330J catalog number.
2. The Series J hardware identification.
3. The 12–120 VAC field supply.
4. The 16-point grouped output arrangement.
5. The total connected load.
6. Terminal-block wiring.
7. BIU and Field Control station configuration.

This check is useful because similar Field Control modules can have different voltage ranges, output characteristics, or wiring arrangements.

Maintenance Notes

Keep field power isolated during module replacement. The Field Control documentation recommends switching off field power before removing or inserting high-voltage I/O modules.

Inspect terminals for loose connections and signs of overheating during routine maintenance. Also check the status LEDs when troubleshooting individual output points.

When storing a spare module, use antistatic packaging and keep it away from excessive moisture, dust, and mechanical shock. Proper identification of the replacement part can also simplify future maintenance.

Why This Module Matters

The IC670MDL330J provides a straightforward way to integrate 16 AC discrete outputs into a GE Fanuc Field Control installation. Its combination of grouped outputs, LED diagnostics, AC load capability, and BIU-based communication makes it suitable for maintaining distributed industrial I/O systems.
