General Electric IC693MDL742 Positive Logic Output Module

The GE IC693MDL742 is a 24VDC Positive Logic Output Module developed for use in the GE Fanuc Series 90-30 PLC system. It provides 16 discrete digital outputs in a compact single-slot form factor and operates using sourcing (positive logic) output configuration, meaning the module provides current to the load.

Designed for interfacing with a wide range of industrial field devices, this module can switch relays, lamps, solenoids, and other discrete components in process control systems. With solid-state output circuitry, LED indicators, and robust electrical isolation, the IC693MDL742 is built for precision and durability in harsh industrial environments.

Frequently Asked Questions (FAQ)

1. Q: What is the primary function of the IC693MDL742?

   A: It is a digital output module that supplies positive logic signals to control external field devices.

2. Q: How many outputs are available on this module?

   A: There are 16 sourcing output channels on the IC693MDL742.

3. Q: Is the module output current limited?

   A: Yes, each output is limited to 0.5 A, with a total module limit of 4.0 A.

4. Q: What does positive logic mean in this context?

   A: Positive logic or sourcing output means the module delivers current to the load from the positive voltage supply.

5. Q: Can this module handle inductive loads such as solenoids or relays?

   A: Yes, but appropriate external suppression diodes or snubbers are recommended to prevent back-EMF.

6. Q: Are the output channels isolated from each other?

   A: The channels are not individually isolated, but the field side is isolated from the logic side.

7. Q: What type of power supply does the module require?

   A: An external 24 VDC power supply is needed for the outputs to function.

8. Q: Can I use this module with GE Series 90-70 systems?

   A: It is specifically designed for the Series 90-30, but compatibility depends on the rack and interface modules.

9. Q: Is there diagnostic information available via software?

   A: The module provides diagnostics through the PLC CPU and visual status via front panel LEDs.

10. Q: Can the module be replaced during system operation?

    A: No, power should be shut down before removing or installing the module to prevent damage or faults.
