Product description

The Siemens 3RS1800-1BP00 is a coupling relay housed in an industrial enclosure, featuring two change-over (CO) contacts. It supports a combination voltage range of 24V and 220-240V AC/DC, with screw terminals for connection. Please note that this is a phased-out product, and its preferred successor is the 3RQ2000-1BW00.

This relay is used to interface control signals between different voltage levels or circuits, providing electrical isolation and amplifying control signals. It's commonly found in control panels for machinery, building automation, and general industrial control applications where signal conditioning or isolation is required.

Stanlo Automation, a veteran-owned supplier of surplus industrial automation parts, offers the Siemens 3RS1800-1BP00 coupling relay. While a phased-out item, we may have stock for your specific needs. Contact us for availability.
