Industrial COM-221 Programmable PLC Output Module

The Square D 8030 COM-221 programmable PLC output module is a 120 VAC output interface in the SY/MAX Class 8030 family, designed to provide programmable, pilot-duty control of external devices from a Square D SY/MAX 8030 controller. It mounts in the 8030 chassis and communicates with the PLC program to switch field loads such as relays, contactors, and other automation devices, enabling precise, repeatable control across multiple outputs. Key aspects include compatibility with 8030 systems and 120 VAC operation suitable for common industrial loads, with the COM-221 part number identifying this specific output module variant. Used in industrial automation and process control, it complements other 8030 I/O modules to implement complex control sequences while maintaining isolation between the controller logic and the controlled circuits.
