System compatibility502-03640-02 belongs to Giddings & Lewis PiC900 control family, also marked as M.1016.9070 R1. Compatible with PiC900 backplane, CPU processor boards and other I/O modules. Widely used on G&L 70A horizontal boring mills, PMC CNC boring machines and heavy machining centers for controlling solenoid valves, lubrication and coolant relays.

Function502-03640-02 is PiC900 32-point 24VDC sourcing digital output module made by Giddings & Lewis. It converts CNC logic commands into 24VDC field output signals. Each channel has overcurrent and short-circuit protection to prevent module damage when field wiring fault occurs. It controls machine auxiliary components including hydraulic solenoids, lubrication pumps, coolant valves and alarm lamps.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack backplane power and external 24VDC field power. Insert 502-03640-02 module into PiC900 backplane slot and lock retainer. Connect field 24VDC wiring to terminal block, separate power cable from signal cable to reduce interference. Assign I/O addresses in PiCPro software. Power on and test each output channel status.

InterfacePiC900 backplane gold-edge connector,field wiring terminal block,on-board OK / CHANNEL STATUS / FAULT LED indicators for Giddings & Lewis 502-03640-02.

DiagnosticOutput channel no power:Check external 24VDC field supply, wiring or channel address configuration. FAULT LED lit:Channel short circuit, overcurrent or backplane communication failure. Individual channel not switching:Output channel burnout or field load fault.
