Product Overview

The GE Fanuc IC693MDR390C provides a versatile, space-saving solution for the Series 90-30 PLC system by combining both input and output functions on a single module. This combination discrete module features 8 channels of 24VDC inputs and 8 channels of Normally Open (N.O.) relay outputs. It effectively manages field signals from sensors while simultaneously switching power loads for actuators, solenoids, and motor starters. We offer this unit as 100% Brand New and Original, ensuring peak performance for distributed control systems and small-scale automation where rack space remains a premium.

Engineering Advantages

Dual-Functionality Optimization: By integrating 8 inputs and 8 relay outputs into a single slot, the IC693MDR390C maximizes I/O density. This reduces the overall cost of the PLC system and minimizes the physical footprint required in small control panels.
High-Voltage Load Switching: The robust Form A relay contacts handle both AC (up to 250V) and DC (up to 30V) loads. This versatility eliminates the need for interposing relays when controlling common industrial components like valves or small motors.
Superior Signal Isolation: Integrated optical and galvanic isolation (1500V) shields the Series 90-30 backplane from field-side electrical noise and high-voltage transients, significantly increasing the lifespan of the CPU module.
Simplified Diagnostics: Front-facing LED indicators provide instant visual verification of both input and output logic states. Maintenance teams can identify signal failures at a glance without utilizing specialized programming software.
Flexible Input Logic: The 24VDC input points support both positive and negative logic, allowing for seamless integration with a variety of sinking or sourcing sensors and field devices.

FAQs

1. Does the IC693MDR390C require external power for the relays?

Yes. While the module draws logic power from the backplane, the relay coils require 24VDC from the rack's power supply or an external source. Additionally, the load being switched by the relay contacts must come from an external power circuit.

2. Can the relay outputs handle high-frequency switching?

Relay modules like the IC693MDR390C are best suited for low-frequency switching (e.g., turning a pump on/off). For high-speed pulse applications or PWM control, we recommend using a transistor output module such as the IC693MDL753 to avoid mechanical wear on the contacts.

3. What is the difference between the "Revision C" (IC693MDR390C) and older versions?

The "C" revision represents the most recent hardware build, incorporating modern component standards and improved thermal dissipation. It remains fully backward compatible with all Series 90-30 racks and older software configurations.

4. Can I mix AC and DC voltages on the relay outputs?

Since the relay contacts provide physical isolation, you can switch different voltages across separate channels. However, you must ensure that each group shares a common return appropriate for the voltage used and adheres to the specified 1500V isolation limits.
