Weidmüller UR20-4RO-CO-255 / Lenze W560-C-2A-007 — relay output module, 4-channel, CO contact, 255 V UC switching voltage, 5 A switching current, 24 V DC, PUSH IN, IP20, u-remote system, order no. 1315550000. A 4-channel relay output module for the u-remote system, equipped with four CO (changeover) contacts and designed for power-intensive actuator applications. Each relay contact is optimised for a maximum switching voltage of 255 V UC (UL: 277 V AC/DC) and a maximum switching current of 6 A per channel, with a total module capacity of 24 A. The module electronics supply the connected actuators from the output current path (UOUT). Compatible with all u-remote fieldbus head stations.
Available in stock — ships within 3 days after payment.

Applications
- Power-intensive AC and DC actuator switching where semiconductor outputs are insufficient — each CO contact handles up to 6 A at up to 255 V UC, making the module suitable for directly switching motors, heating elements, contactors, solenoid valves, and other high-current or mains-voltage loads without additional interposing relays
- Changeover contact (CO) topology allows both normally-open and normally-closed load circuits per channel, enabling fail-safe wiring strategies and bidirectional switching in the same module position
- Mixed AC/DC load environments where a single module must switch loads at different voltages or current types — the relay contact is voltage- and polarity-agnostic up to the rated switching voltage, unlike solid-state output modules
- Applications requiring galvanic isolation between the u-remote control circuit and the switched load circuit, providing inherent noise immunity and protection in electrically demanding industrial environments
- Hazardous area installations (ATEX/IECEx) and marine applications requiring certified relay output modules with ABS, ClassNK, DNV, and KR approvals
