This input-output (I/O) module from Rockwell Automation's Allen Bradley range secures to your programmable logic controller (PLC) to process commands for your machinery. As part of a PLC setup, it assists in sending control instructions to electrical devices so your system can run smoothly. The module communicates between the central processing unit (CPU) and the machine controls, converting commands to signals that are compatible with each particular machine. Units like this are commonly used in industrial automation setups.
