MeloAuto-Trusted PLC & DCS Parts Supplier
The GE A03B-0807-C108 provides reliable emergency stop functionality for GE Fanuc CNC controls. You can install this module directly into the safety circuit of Series 15 or 16 controllers. It monitors the emergency stop string and disables servo drives instantly. This unit ensures operator safety in machining centers and robotic cells.
Technical Specifications and Hardware Layout
This emergency stop module measures 260 mm in height. Its width reaches 120 mm, and the depth equals 45 mm. The GE A03B-0807-C108 weighs approximately 0.45 kilograms. A single internal PCB holds all monitoring and switching circuits. The module contains no energy storage capacitors or batteries. Two 12-pin terminal blocks handle all emergency stop wiring connections. One 50-pin ribbon connector interfaces with the CNC backplane. Three status LEDs indicate safety circuit and module health.

Safety Circuit Specifications and Performance
The GE A03B-0807-C108 monitors four independent emergency stop input channels. Each input accepts 24 V DC signals from pushbuttons and safety gates. The module requires a dual-channel circuit for SIL 2 safety integrity. Consequently, this design meets international machinery safety standards. The safety relay outputs switch 2 A at 250 V AC or 30 V DC. Response time from input activation to output shutdown stays below 20 milliseconds. Internal diagnostics check for cross circuits and short circuits continuously.
Installation and Compliance Guidelines
You must insert this module into a dedicated CNC rack slot. Transitioning to wiring, use shielded cables for all safety input connections. The module includes a reset input for manual restart after emergency stops. Three LEDs show power, safety circuit status, and fault conditions clearly. Always test the emergency stop function weekly during operation. The operating temperature range spans from 0°C to 55°C reliably.
