Why Choose the ABB CR-U110DC2LD Pluggable Relay?

The ABB CR-U110DC2LD is a robust and versatile pluggable universal interface relay designed for electrical isolation, signal amplification and signal matching in industrial control and automation systems. As part of the ABB CR-U pluggable relay range, it provides a reliable interface between electronic control equipment such as PLCs, industrial PCs and fieldbus systems and the sensor or actuator level.

This relay features 2 changeover (2 C/O) contacts and a 110 V DC rated control supply voltage, providing flexible switching for industrial control circuits. The CR-U range incorporates an integrated manual test button for convenient circuit checking, while its modular pluggable construction allows the relay to be combined with compatible ABB sockets and function modules.

With 2 C/O (DPDT) contacts and a contact current rating of 10 A, the CR-U110DC2LD is suitable for demanding interface and switching applications in industrial machinery and control panels. The relay also incorporates LED status indication and a free-wheeling diode, providing visual operating feedback and coil suppression for its 110 V DC control circuit.
