GE A03B-0801-C117 PLC AC Output Module

The GE A03B-0801-C117, also cataloged as the A03B-0801-C117 Output Module OA16D, operates as a dedicated hardware component for discrete AC load control execution within PLC/Machine Control platforms.

Hardware Specifications

Backplane Communication and I/O Density Scaling

The module handles backplane bus communication velocity across the host rack chassis, accepting fast logic commands from the main CPU and transferring them to field-side triac/relay drive channels. Designed for balanced I/O density scaling, the unit provides galvanic isolation between internal backplane logic and external 120 VAC load circuits. Integrated firmware flash compatibility ensures synchronized output state transitions during deterministic machine control execution.

Frequently Asked Questions

Q: What precautions should be taken when driving inductive loads with the OA16D module?

A: External RC snubber networks or surge suppressors should be connected across inductive field loads (such as solenoids or contactor coils) to protect the module's 120 VAC output switching components from inductive voltage spikes.

Q: Can channels on the A03B-0801-C117 be hot-swapped while field voltage is applied?

A: No. Disconnect both the control rack power supply and the external 120 VAC field power source before removing or inserting the module to prevent electrical arcing and logic backplane damage.

Field Installation Guidelines

Align the module with the card guide tracks in the host chassis and press firmly until the backplane connector locks into place. Verify that field wiring for the 120 VAC outputs is routed in separate conduit or cable trays away from low-voltage analog and communication lines. Ensure the chassis terminal strip grounding conductor is bonded directly to the main system earth ground bar to maintain stable noise immunity.
