GE A03B-0807-C159 AC Output Module for GE Fanuc CNC Systems

The GE A03B-0807-C159 switches AC loads 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 triac output channels for 115 V AC or 230 V AC loads. This unit suits solenoid valves, motor starters, and indicator lamps.

Technical Specifications and Hardware Layout

This AC output module measures 260 mm in height. Its width reaches 120 mm, and the depth equals 45 mm. The GE A03B-0807-C159 weighs approximately 0.52 kilograms. A single internal PCB holds all output switching and isolation circuits. The module provides sixteen triac outputs for AC 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-C159 switches loads at 115 V AC or 230 V AC nominal. Each channel handles a continuous current of 1 A maximum. The total current per module reaches 8 A. Each output includes an internal snubber circuit for inductive loads. Consequently, this module reduces contact wear on external relays and contactors. The triac outputs switch at frequencies up to 10 Hz for cycling applications. Optical isolation separates the field side from the CNC backplane logic. The module requires no external fuses for short-circuit protection.

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 highly inductive AC loads, add external RC snubbers for extra protection. Always power off the CNC before removing or inserting the module. The operating temperature range spans from 0°C to 55°C reliably.
