IC200MDL744 | GE VersaMax Discrete Output Module

GE Fanuc IC200MDL744 VersaMax Discrete Output Module — 32-Point, 5/12/24VDC Negative Logic, 0.5A

The IC200MDL744 is a 32-point discrete output module from the GE Fanuc VersaMax series. It provides two groups of 16 negative-logic (sinking) outputs that switch loads to the negative side of the DC supply. The module supports 5VDC TTL mode and 12/24VDC mode, making it ideal for mixed-voltage control panels and compact distributed I/O architectures.

Thermal Derating

Maximum simultaneous ON points depend on ambient temperature, external voltage, and module/DIN rail orientation. Derating charts available in official manual GFK-1504.

Installation Guide

1. Mount on compatible VersaMax I/O carrier (IC200CHSxxx series).
2. Provide external DC power supply for field-side operation.
3. Wire outputs in two groups: Group 1 (Outputs 1–16) and Group 2 (Outputs 17–32), each with dedicated DC+ and DC- terminals.
4. Use external suppression circuits for inductive loads.
5. Verify FLD PWR and OK LEDs illuminate after power-up.

FAQ

Q: Is IC200MDL744 positive or negative logic?
A: Negative logic (sinking). Outputs switch loads to the negative/return side and receive current from the load.

Q: What voltage modes does it support?
A: 5VDC TTL mode (4.75–5.25V) and 12/24VDC mode (10.2–30V). Select mode via external power supply voltage.

Q: Does it have internal fuses?
A: No. Install external fuses or circuit breakers for output protection.

Q: What is the maximum inrush current?
A: 2.0 A per point for 100 ms maximum.

Q: Can I use shorting bars for additional bussed terminals?
A: Yes. Shorting bars can make B terminals available with a max current capacity of 2 A per point.

Selection Tips

• 32-point negative logic, 5/12/24VDC: IC200MDL744
• 16-point negative logic, 5/12/24VDC: IC200MDL743
• 32-point positive logic, 24VDC with ESCP: IC200MDL742
• 32-point positive logic, 12/24VDC: IC200MDL750
• Always verify: Logic type (positive vs. negative), voltage range, and ESCP requirements before ordering
