5B9042F0 Digital I/O Module

Feature & Principle

It is a field I/O module for distributed control system. It collects on-site switch status or outputs switch commands to actuators. Each channel has independent overcurrent and short-circuit protection circuit, and the module feeds back channel fault information to the controller through the backplane bus. It supports hot swap, built-in status indicator light, and can be quickly replaced without stopping the control loop.
