Product Overview

The GE IC693MDL390 is a robust 8-point isolated AC output module designed for the GE Fanuc Series 90-30 PLC family. It is specifically engineered for applications requiring 240 VAC output switching, with each output channel electrically isolated from the others, making it an ideal solution for high-integrity systems that demand independent channel protection and fail-safe operation.

This module is fitted with solid-state TRIAC switching devices and built-in snubber circuits, which ensure smooth operation even under inductive load conditions such as solenoids and contactors. The electrical isolation between channels enhances safety and noise immunity, which is critical in industrial automation environments where electrical transients and grounding issues are prevalent.

Designed for seamless integration with GE’s Series 90-30 backplane architecture, the IC693MDL390 offers high reliability, easy installation, and long-term service life. Each channel includes its own LED indicator, enabling real-time output status monitoring during operation.

Applications

The GE IC693MDL390 is purpose-built for use in a broad array of medium-to-high voltage AC control applications. Its isolated outputs make it uniquely suited to installations where cross-talk, electrical interference, or grounding differences between devices must be mitigated.

Typical application scenarios include:

• Industrial machinery control systems

• Electrical utility substations

• Motor starter activation in distributed systems

• Traffic control signal switching

• Oil and gas instrumentation

• Municipal water/wastewater systems

• HVAC system control in large facilities

• Power plant auxiliary systems

• Packaging line automation

• Food and beverage process lines

The isolated design ensures that a fault on one output does not affect the operation of others, thus increasing system robustness.

Frequently Asked Questions (FAQ)

1. What type of loads can the IC693MDL390 control?
   It can control resistive and inductive AC loads such as solenoids, relays, and motors rated at 240 VAC.

2. Are the output channels electrically isolated from each other?
   Yes, each of the 8 channels is fully isolated at 1500 VAC.

3. Can this module be used for DC output switching?
   No, the IC693MDL390 is designed strictly for AC voltage applications.

4. What is the maximum current each channel can handle?
   Each channel can handle a continuous output current of 0.25 A.

5. Is this module hot-swappable?
   No, you must power down the system before installing or removing the module.

6. Does the module have overload protection?
   No internal fuse exists per output; external protection (fuses/breakers) is recommended.

7. Can I mix inductive and resistive loads on the same module?
   Yes, but each channel should be independently protected and verified for compatibility.

8. Is there any inrush current limitation?
   Inrush current capacity is limited by the TRIAC; high-inrush loads should be externally suppressed.

9. How is the module connected to the system?
   It plugs into the GE Series 90-30 baseplate and uses a removable terminal block for field wiring.

10. Are there onboard diagnostics?
    Diagnostic feedback is available through CPU logic, and LED indicators show channel status.
