System compatibility028-25574-03 belongs to Giddings & Lewis PiC900 control family. Compatible with PiC900 backplane,CPU processor board and other I/O modules. Widely applied on G&L horizontal boring mills and CNC machining centers for pressure, temperature and speed analog signal processing.

Function028-25574-03 is PiC900 analog I/O board manufactured by Giddings & Lewis. It converts field analog sensor signals into digital data for CNC system, and converts CNC digital commands to analog output to control spindle speed or proportional hydraulic valves. Galvanic isolation protects CNC rack from field noise interference. It is commonly used for hydraulic pressure, lubrication and spindle speed monitoring on heavy machine tools.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack backplane power. Insert 028-25574-03 module into PiC900 backplane slot and lock retainer. Connect shielded analog sensor and actuator cables. Configure channel scaling and signal range in PiCPro software. Power on and verify analog signal reading and output.

InterfacePiC900 backplane gold-edge connector,terminal block for analog field wiring,on-board OK / ACT / FAULT LED indicators for Giddings & Lewis 028-25574-03.

DiagnosticIncorrect analog reading:Check cable shielding, signal wiring or channel scaling parameter. FAULT LED lit:Backplane communication error or channel overrange alarm. No analog output:Channel configuration disabled or field device wiring fault.
