The A03B-0815-C003 is a Type-2 external digital I/O expansion module designed for FANUC connection panel installations in i-Series CNC controls (16i/18i/21i), 0i-D/0i-F, and 30i/31i/32i-class machines. This module provides 24 digital inputs and 16 digital outputs through robust connector interfaces, expanding the machine’s I/O capacity without requiring additional I/O racks. The module supports daisy-chain configuration with other C001, C002, and C003 modules for large-scale I/O requirements. Note: This variant does not include MPG interface.
