System compatibility

502-03427-00 belongs to DANAHER MOTION Giddings & Lewis legacy CNC rack family. Compatible with older Giddings & Lewis CPU board, analog servo control boards and encoder feedback cards. Widely used on heavy-duty boring mills, vertical turning centers and horizontal machining centers.

Function

502-03427-00 is DC digital output PCB board manufactured by DANAHER MOTION Giddings & Lewis. It receives digital commands from CNC main processor, then switches 24VDC field outputs to drive machine relays, solenoids and auxiliary actuators. Optical isolation isolates CNC logic from machine side electrical surge. Channel LEDs help maintenance technicians quickly identify faulty output channels during machine troubleshooting.

Installation

Follow lockout/tagout safety procedure before installation. Cut off all power of CNC rack. Insert 502-03427-00 gold finger card into empty rack slot and lock retention bracket. Connect field actuator wiring to terminal block according to Giddings & Lewis hardware manual. After wiring, power on and test each output channel one by one.

Interface

Gold-edge backplane connector, field output terminal block, on-board channel status LED indicator for DANAHER MOTION 502-03427-00.

Feature

Original DANAHER MOTION 502-03427-00 DC output interface PCB board,opto-isolated 24VDC output,per-channel short-circuit protection,LED diagnostic indicators,gold finger rack plug-in design,anti-interference circuit,UL & CE certified. This spare unit is used for legacy heavy CNC machine I/O control system maintenance and hardware replacement.

Diagnostic

No output action: Check rack backplane power, channel enable signal and field wiring. Channel burnout: Inspect overload or short circuit of solenoid/relay load. Intermittent output failure: Verify cable shielding, grounding and surrounding electromagnetic interference.
