System compatibility

501-02989-00 belongs to DANAHER MOTION Giddings & Lewis legacy CNC rack family. Compatible with older Giddings & Lewis CPU board, servo axis control boards and encoder feedback cards. Widely installed on heavy-duty boring mills, vertical and horizontal CNC machine tools.

Function

501-02989-00 is digital I/O interface PCB board manufactured by DANAHER MOTION Giddings & Lewis. It exchanges digital signals between CNC main processor and machine field peripherals such as limit switches, proximity sensors, relays and indicator lamps. Optical isolation separates machine field noise from sensitive CNC logic circuits. The onboard LEDs help maintenance personnel quickly locate signal faults during machine troubleshooting.

Installation

Follow lockout/tagout safety procedure before installation. Completely power off CNC rack. Insert 501-02989-00 gold finger card into empty rack slot and lock retention bracket. Wire field I/O cables to terminal block following Giddings & Lewis hardware manual. Power on and execute point-by-point I/O function test after wiring.

Interface

Gold-edge backplane connector, field signal terminal block, status LED indicator for DANAHER MOTION 501-02989-00.
