Siemens 3RS1020-1DD20

This temperature monitoring relay is configured for PT100 sensors, facilitating over-temperature monitoring across a range of 0 to +200 degrees Celsius. It operates at a control voltage of 24V AC/DC and features a compact width of 22.5 mm, making it suitable for various applications where space is constrained.

Equipped with two sensor inputs, this device provides a single change-over contact and one normally open contact. The unit measures 91 mm in depth and 102 mm in height, with a screw terminal connection type ensuring secure and reliable wiring. Notably, it does not support external reset and does not allow for error registration.

With a total of one measuring circuit, the relay is designed for straightforward installation and robust performance in temperature monitoring tasks. This product, classified under the designation code, is a phased-out item, with the preferred successor being 3RS2600-1BA30.
