5501-381 wooDWARD1/ О Module: The external function of PLC is mainly to communicate with the outside world through various I/O interface modules. The module specifications and quantities are determined based on the number of I/O points. The number of I/O modules can be many or few, but their large number is limited by the ability to manage the basic configuration, that is, by the large number of chassis or rack slots. The I/O module integrates the I/O circuit of the PLC, with the input register reflecting the status of the input signal and the output point reflecting the status of the output latch. Power module: Some PLCs have power supplies that are integrated with the modules, while others are separate. Their main purpose is to provide working power for the integrated circuits of each PLC module.

The WOODWARD 5501-381 power module also provides 24V working power supply for the input circuit. The power supply has the following input types: AC power supply, with added AC 220V or 110VAC, DC power supply, with added DC voltage, and commonly used 24V. Bottom plate or rack: Most modular PLCs use a bottom plate or rack, which is used to electrically connect various modules and enable access to all modules on the bottom plate. Mechanically, it enables connections between modules and forms a whole. The external equipment of PLC is an integral part of the PLC system.
