GE A03B-0807-C171 DC Output Module for GE Fanuc CNC Systems

The GE A03B-0807-C171 drives DC actuators directly from GE Fanuc CNC controls. You can install this module into the main CNC rack of Series 15 or 16 controllers. It provides sixteen transistor output channels for 24 V DC loads. This unit suits solenoid valves, contactors, and indicator lamps.

Technical Specifications and Hardware Layout

This DC output module measures 260 mm in height. Its width reaches 120 mm, and the depth equals 45 mm. The GE A03B-0807-C171 weighs approximately 0.50 kilograms. A single internal PCB holds all output driving and isolation circuits. The module provides sixteen sinking transistor outputs for DC loads. It stores no energy in capacitors or internal batteries. One 96-pin front connector handles all field wiring connections. Sixteen red LEDs display the real-time status of each channel.

Output Specifications and Electrical Ratings

The GE A03B-0807-C171 switches outputs at 24 V DC nominal. Each channel handles a continuous current of 0.5 A maximum. The total current per module reaches 8 A. Short-circuit protection limits each output to 1 A for fault conditions. Consequently, this module survives wiring errors without permanent damage. Output switching frequency reaches 100 Hz for rapid cycling tasks. Each channel includes an internal freewheeling diode for inductive loads. Optical isolation separates the field side from the CNC backplane logic.

Installation and Practical Application Tips

You must insert this module firmly into a dedicated CNC rack slot. Transitioning to wiring, use 0.5 mm² to 1.5 mm² stranded copper wire. The screw-type terminals require a 3 mm flathead screwdriver for tightening. For inductive loads, the internal diodes provide adequate suppression. Always power off the CNC before removing or inserting the module. The operating temperature range spans from 0°C to 55°C reliably.
