The FANUC A03B-0819-C101 (AID32A1) is a high-density digital input module designed for the FANUC I/O Unit-A distributed I/O system, commonly used in CNC machines, robots, and automation equipment. It provides 32 isolated DC inputs grouped in 4 banks of 8 points each (8 points/common), accepting 24 VDC signals (+10%/-20%) from sensors, switches, and field devices. Each input draws 7.5 mA average current with minimum ON voltage/current of 15 VDC/4.5 mA and maximum OFF leakage of 1 mA.

This module supports both sink and source wiring (positive/negative logic), 2 ms response time, and installs on I/O Unit-A base units via backplane connection to FANUC CNC/PMC masters. It features LED status indicators per point and operates reliably in industrial environments with optical isolation and surge protection. Compact design fits standard I/O racks for space-efficient panels.
