Omron CQM1-PA216 CQM1 Power Supply Unit

Description

Engineered to power CQM1-series programmable controllers, the Omron CQM1-PA216 delivers reliable, regulated power to the system backplane and associated modules. This modular power supply unit accepts selectable AC input voltages, generating both 5 VDC logic power for internal CPU circuitry and 24 VDC auxiliary power for external sensor or output interfaces. With a total integrated power capacity of 30 W, the CQM1-PA216 manages complex dynamic loads while maintaining system stability and protecting internal components from line-voltage fluctuations and transient electrical noise.

Features

• Flexible AC input configuration with selectable 100 VAC or 230 VAC operating modes.
• Dual DC output rails providing 5 VDC at 6.0 A and 24 VDC at 0.5 A.
• High-capacity noise immunity of 1500 Vp-p to isolate control logic from industrial grid interference.
• Robust inrush current protection limiting peak startup current to 30 A.
• Compact, screw-terminal interface designed for rapid field wiring and secure connection retention.

Applications

• Factory automation and legacy machine tool control panels.
• Material handling and packaging conveyor line synchronization.
• Pumping stations and local water treatment telemetry systems.
• Automotive subsystem assembly lines requiring local PLC deployment.

Installation Guidelines

• Voltage Selection: Always verify that the input voltage selection matches local supply levels before applying power to avoid unit damage.
• Thermal Considerations: Install the power supply in a standard vertical orientation on the PLC backplane to allow adequate heat dissipation. Maintain a minimum clear distance of 50 mm above and below the assembly.
• Grounding: Connect the GR terminal directly to a dedicated ground point using a thick-gauge wire to maximize noise suppression and guarantee electrical safety.
• Load Planning: Verify that the total dynamic current consumption of the CPU unit and all connected I/O modules on the rack does not exceed the combined 30 W limit.
