System compatibilityM.1016.9338 belongs to Giddings & Lewis PiC900 control platform. Compatible with PiC900 CPU processor boards, backplane, analog I/O and SERCOS communication modules. Widely deployed on G&L 70A horizontal boring mills and PMC CNC boring machines.

FunctionM.1016.9338 is PiC900 digital I/O expansion module manufactured by Giddings & Lewis. It exchanges discrete logic signals between PiC900 CPU and machine field devices. It reads limit switches, safety interlock and pushbutton signals, and drives solenoid valves, relays and indicator lamps. Hardware filter suppresses signal jitter caused by mechanical switches and electrical interference. It is common spare I/O card for legacy heavy G&L CNC machine tools.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack backplane power and external 24VDC field supply. Insert M.1016.9338 module into PiC900 backplane slot and lock retainer. Separate high-power wiring and signal wiring to reduce EMI interference. Configure I/O address mapping via PiCPro software. Power on rack and verify each input and output channel function.

InterfacePiC900 backplane gold-edge connector,field wiring terminal block,on-board OK / CHANNEL STATUS / FAULT LED indicators for Giddings & Lewis M.1016.9338.

DiagnosticChannel no response:Check external 24VDC field supply, wiring polarity or I/O address configuration. FAULT LED lit:Channel short circuit, overcurrent or backplane communication failure. Unstable signal:Insufficient cable shielding or mechanical switch contact degradation.

Product BriefM.1016.9338 is Giddings & Lewis legacy PiC900 digital I/O expansion module,for interlock,switch signal collection and auxiliary actuator control on heavy CNC boring mills,discontinued CNC I/O spare card.
