GE Fanuc IC693MDR390C Series 90-30 Mixed I/O Module
Configured for discrete signal acquisition and load switching in Series 90-30 PLC platforms, the GE Fanuc IC693MDR390C (IC693MDR390 Mixed I/O Module) provides direct physical/electrical execution. Operating on the local backplane, the unit processes 8 discrete 24 VDC input channels while driving 8 Normally Open (N.O.) relay contact outputs to interface external field devices directly with system logic memory.

Backplane Bus Communication Velocity & Firmware Flash Compatibility
The IC693MDR390C exchanges discrete status data with the CPU across the parallel backplane bus during each I/O scan sweep. Optocoupler circuits and electromechanical contact isolation prevent high-voltage switching transients on output channels from disrupting backplane bus communication velocity. Hardware firmware flash compatibility across Series 90-30 baseplate revisions guarantees stable scan timing and reliable state updates during continuous control execution.
Frequently Asked Questions
Q: Can the output contacts on the IC693MDR390C switch both AC and DC loads on adjacent channels?
A: Yes, each isolated Form A relay contact operates independently, allowing simultaneous control of AC loads up to 250 VAC and DC loads up to 30 VDC across separate output circuits.
Q: How does the IC693MDR390C indicate channel states for debugging and field validation?
A: The front panel houses individual status LEDs for both the 8 discrete input channels and the 8 relay output channels, providing real-time visual verification of logic states.
Field Installation Guidelines
- Disconnect backplane power and field voltage sources before inserting or removing the module from the Series 90-30 baseplate.
- Route high-voltage AC output wiring in separate conduit pathways away from low-voltage 24 VDC input and communication cables.
- Install external arc suppressors or RC networks across inductive loads (such as contactor coils and solenoids) to prevent contact pitting and severe electrical noise.
- Confirm that field wiring grounds attach securely to the cabinet earth bar to preserve field-to-logic galvanic isolation integrity.
