Giddings & Lewis 502-03064-10 Digital I/O Board

Technical SpecificationsModel：502-03064-10 Brand：Giddings & Lewis Product Type: Rack mount dual-section digital I/O PCB assembly for legacy NumeriPath 8000 /8000B CNC platform

Module Feature:Function: Digital I/O board for G&L NumeriPath CNC system. It collects discrete digital input signals from machine limit switches, emergency stop, proximity sensors and safety interlocks; outputs digital control signals to relays, contactors and machine actuators for heavy horizontal boring mills and large machining centers. Board structure: Dual independent I/O sections, individual fuse protection for output circuits Signal: 24VDC discrete digital input and output channels LED indicators per channel for status visualization Bus: Parallel backplane gold finger connector to exchange I/O data with CNC main CPU LED indicators: POWER, ACT, FAULT diagnostic lights Hardware self-diagnosis: Backplane communication integrity test, channel short-circuit detection, I/O circuit fault alarm Programming software: G&L proprietary CNC software for I/O address mapping and channel diagnostic test

Electrical ParametersBackplane supply:+5VDC Field I/O supply:24VDC Power consumption:Max 10.5W

Mechanical & Structure:Mounting: Rack slot mount large PCB assembly Weight:1.3kg Protection class:IP20

Environmental:Operating temperature:0℃ ~ +55℃ Ambient humidity:5~85% non-condensing Certification:CE Status:Manufacturer discontinued legacy CNC digital I/O board

System compatibility502-03064-10 belongs to Giddings & Lewis NumeriPath 8000 CNC family. Compatible with matching rack backplane, executive CPU and operator station boards. Widely fitted on vintage heavy G&L horizontal boring mills.

Function502-03064-10 is digital I/O board manufactured by Giddings & Lewis. It acts as signal interface between CNC controller and machine field discrete devices. It reads safety interlock, jog, limit and sensor signals, then executes output control for spindle, coolant and auxiliary machine functions. Each output channel has independent fuse for overload protection. It is legacy digital I/O spare for old heavy G&L CNC boring mills.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack +5V backplane power and 24VDC field power. Insert 502-03064-10 board into rack slot and secure gold finger connector. Wire 24VDC field I/O signals with shielded cables. Configure I/O address mapping, run board self-test and verify all input and output channels.

InterfaceBackplane gold finger connector, multi-channel screw terminal blocks for field I/O,on-board POWER / ACT / FAULT LED indicators for Giddings & Lewis 502-03064-10.

DiagnosticI/O channel no response:Check 24VDC field supply, wiring or blown channel fuse. FAULT LED lit:Backplane communication failure or short circuit on field output channel. Random signal dropout:Ground loop interference or poor terminal contact.

Product Brief502-03064-10 is Giddings & Lewis legacy dual-section digital I/O board for NumeriPath CNC system,for heavy CNC boring mill discrete sensor input and auxiliary actuator output control,discontinued CNC I/O PCB spare.
