Overview
The Opto22 PB16A is a compact G1 16-channel I/O module mounting rack designed for industrial automation and control applications. This rack provides a direct-connect interface for up to 16 single-channel Opto 22 standard (Generation 1) digital I/O modules, making it an essential component in modular control systems where field I/O expansion is required without redesigning the entire control architecture.
Key Features
