GE Fanuc A03B-0807-C167 Digital Output Module

Configured for high-speed discrete switching in Fanuc I/O system platforms, the GE Fanuc A03B-0807-C167 (A03B-0807-C167 Digital Output Module) provides direct physical/electrical execution. It interfaces 32 DC output channels directly with the control rack backplane to execute high-density field actuator control loops.

Hardware Specifications

Backplane Bus Communication and Deterministic Logic Execution

The module operates using deterministic backplane bus communication velocity to manage real-time signal transmission for all 32 output channels simultaneously. High I/O density scaling optimizes cabinet space efficiency without causing thermal thermal buildup across adjacent I/O slots. Firmware flash compatibility ensures synchronized cyclic scan execution with the main PLC logic CPU, preventing output state propagation delays.

Frequently Asked Questions

Q: What is the physical channel capacity of the A03B-0807-C167 module?

A: The module contains 32 discrete DC output channels (designated as AOD32D2) configured to drive external relay coils, solenoids, and status indicators.

Q: Can the module be removed from the I/O base while field power is applied?

A: No. Field supply power and system control power must be completely de-energized prior to removing the module to prevent electrical arcing and logic corruption on the I/O bus.

Field Installation Guidelines

1. De-energize all primary power supplies feeding the I/O rack and external DC field circuit loops.
2. Verify that the I/O base unit is grounded to the main cabinet panel via low-impedance grounding straps.
3. Align the module housing guides with the corresponding slot on the I/O mounting rack or DIN rail base.
4. Firmly press the module until the backplane multi-pin connector seats completely and retaining latches snap shut.
5. Terminate field wiring harnesses to the front connector block, ensuring strain relief ties are secured to prevent mechanical tension on the terminals.
