- The BIU sends one byte of output commands to the module.
- A protected FET stage sources current to each field load.
- A persistent overload switches the affected point off and returns a circuit fault.

Model Profile
GE Fanuc IC670MDL730 is an eight-point 24 VDC positive-logic output module with electronic short-circuit protection. It sources current to field loads and monitors each output for overcurrent or short-circuit conditions.
When a fault is detected, the affected point is switched off and a diagnostic is reported to the bus interface unit. Separate green state LEDs and yellow fault LEDs help distinguish a commanded output from a channel that has been disabled by protection.
The module is intended for 18–30 VDC field supplies and loads up to 2 A per point, subject to an 8 A module total. Compatibility with the installed BIU revision must be checked because the point-level diagnostics require supported interface firmware.

Selection detail
Protection Coordination
- Keep steady current below 2 A per point and 8 A for the module.
- Use the required BIU revision so channel diagnostics are handled correctly.
- Clear a latched circuit fault only after the field wiring or load problem has been removed.
Buyer decisions
Technical Questions
Why does an IC670MDL730 output stay off even after the command returns ON?
A channel fault can latch the point off; remove the overload or short circuit and then clear the fault.
Can IC670MDL730 deliver 2 A on all eight outputs simultaneously?
No. The module total is limited to 8 A even though each point is rated up to 2 A.
Which Genius BIU revision is required for IC670MDL730?
Use IC670GBI002 revision 2.10 or later for the specified compatibility.
What do the yellow LEDs on IC670MDL730 indicate?
They identify point-level overcurrent or short-circuit faults, separate from the green output-state LEDs.
Can IC670MDL730 drive a sinking-input field device?
It is a positive-logic sourcing output, so the connected load must be wired for sourced current.
What buyer data is needed for IC670MDL730?
Provide load current, inrush, supply voltage, BIU model/revision and module-total duty.
