Overview
The Omron CQM1-PA203 is a compact AC power supply designed for the SYSMAC CQM1 series programmable controller platform. It accepts universal AC input (100–240 VAC) and provides stabilized 5 VDC and 24 VDC outputs to power controller units and I/O modules. This unit is essential for maintaining legacy automation systems and serves as a drop-in replacement for existing SYSMAC installations.
Key Features
