GE Fanuc IC200MDL243D VersaMax Discrete Input Module

The IC200MDL243D is a 16-point discrete input module manufactured by GE Fanuc for the VersaMax I/O platform. Operating at 24 VDC, this module reads discrete signals from field devices such as pushbuttons, limit switches, and proximity sensors, passing the field status across an optically isolated barrier to the VersaMax controller or network interface unit.

Input Configuration and Logic Flexibility

The module features 16 input channels that accommodate an input voltage range of 0 to 30 VDC, drawing a nominal input current of 7 mA per point at 24 VDC. Designed to support flexible field wiring schemes, the module accepts both sourcing and sinking input logic. Fast signal transitions are captured with an input delay time of 1 ms for both ON and OFF states.

System Integration and Status Monitoring

The module draws 120 mA at 5 VDC from the VersaMax backplane and connects to field wiring via a removable terminal block base. Electrical isolation of 1500 V RMS protects logic-side components from field transients. Status diagnosis is facilitated by individual green LED indicators for each input point alongside a dedicated module OK LED.

Frequently Asked Questions

Q: Does the IC200MDL243D require specific wiring configurations for sinking versus sourcing devices? A: The module supports both sinking and sourcing field configurations, allowing flexibility depending on how the common reference potential is connected across the input groups on the terminal block base.

Q: How are channel status and health monitored on the module front panel? A: Each of the 16 inputs features an individual green LED indicator that illuminates when field signal voltage is present, while a separate module OK LED displays overall system status.
