Information About CQM1-OC221
The CQM1-OC221 belongs to Omron’s CQM1 Series, a modular PLC system offering flexible configuration for machine and process control. This module provides 8 relay-type contact outputs capable of handling both AC and DC loads, making it suitable for actuators, solenoids, lamps, and relay-driven devices. With independent common terminals, it allows mixed-voltage or isolated circuit configurations. The unit’s ON and OFF delay times of 10 ms and 5 ms respectively ensure stable switching performance, while its 430 mA internal current consumption at 5 VDC maintains efficient power usage within the PLC rack. Designed for durability, the CQM1-OC221 employs Omron’s proven reliability and is compatible with existing CQM1 and CQM1H system configurations.
Key Features:
- 8-Point Relay Output: Provides flexible control for AC and DC loads up to 2A per point.
- Wide Voltage Range: Supports 250 VAC or 24 VDC switching for diverse applications.
- Independent Common Terminals: Enables separate circuits or mixed-voltage configurations.
- Fast Switching Performance: 10 ms ON delay and 5 ms OFF delay for reliable signal timing.
- DIN Rail Mounting: Simplifies installation in control panels and PLC racks.
- Low Internal Power Consumption: Draws only 430 mA at 5 VDC from the base unit.
- Terminal Block Connector Type: Facilitates secure and easy field wiring.
- Legacy Compatibility: Designed for integration with Omron CQM1 and CQM1H PLC systems.
The CQM1-OC221 delivers the reliability and precision required for output control in manufacturing automation, machinery operation, and process equipment.
