Giddings & Lewis M.1016.9333 Digital Input Module

Technical SpecificationsModel：M.1016.9333 Brand：Giddings & Lewis Product Type: Single-slot plug-in PiC900 series 32-point 24VDC sinking digital input module for PiC900 rack backplane

Module Feature:Function: Digital signal acquisition board for PiC900 CNC control system, reads 24VDC discrete signals including limit switches, proximity sensors, safety interlock and push-button status on heavy-duty machine tools. Channel count:32 sinking digital input channels Nominal field voltage:24VDC, operating range 5~32VDC Input filter:Built-in hardware debounce filter to eliminate mechanical switch signal bounce Isolation:Opto-isolation between field side and rack backplane LED indicators: OK, CHANNEL STATUS, FAULT diagnostic lights Hardware self-diagnosis:Backplane bus communication monitoring, overvoltage protection, input channel status detection Programming software:PiCPro for I/O address assignment and channel diagnostic testing

Electrical ParametersBackplane supply:+5VDC from PiC900 rack backplane Field supply:External 24VDC for field sensors Power consumption:Max 3.0W External 24VDC field power required for sensor circuits

Mechanical & Structure:Mounting:Plug into PiC900 rack single slot Weight:0.21kg Protection class:IP20

Environmental:Operating temperature:0℃ ~ +60℃ Ambient humidity:5~85% non-condensing Certification:CE Status:Manufacturer discontinued legacy CNC I/O module

System compatibilityM.1016.9333 belongs to Giddings & Lewis PiC900 control platform. Compatible with PiC900 backplane, CPU processor boards, analog I/O and digital output modules. Widely installed on G&L 70A horizontal boring mills and PMC CNC boring machines.

FunctionM.1016.9333 is PiC900 32-channel 24VDC sinking digital input module made by Giddings & Lewis. It transfers discrete machine status signals to PiC900 controller via rack backplane. Opto-isolation protects the CNC rack from electrical noise and surge from machine field wiring. It collects axis travel limit, door safety interlock, hydraulic and lubrication status feedback signals for CNC logic control.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack backplane power and external 24VDC field supply. Insert M.1016.9333 module into PiC900 backplane slot and lock retainer. Route signal cables separately from high-power motor cables to reduce EMI. Configure I/O address mapping in PiCPro software. Power on rack and verify each input channel response.

InterfacePiC900 backplane gold-edge connector,field wiring terminal block,on-board OK / CHANNEL STATUS / FAULT LED indicators for Giddings & Lewis M.1016.9333.

DiagnosticNo signal reading:Check external 24VDC field power supply, wiring polarity or I/O address setup. FAULT LED lit:Field side overvoltage or backplane communication failure. Unstable signal:Missing cable shielding or worn mechanical switch contacts.

Product BriefM.1016.9333 is Giddings & Lewis legacy PiC900 32-point 24VDC sinking digital input module,for collecting safety interlock and limit switch signals on heavy CNC boring mills,discontinued CNC I/O spare card.
