Monitoring Relays

3RS10, 3RS11 Temperature Monitoring Relays

Relays, analog adjustable

7/90

Siemens LV 1 T · 2006

■Overview

The 3RS10/3RS11 analog temperature monitoring relays can be

used for measuring temperatures in solid, liquid and gas media.

The temperature is sensed by the sensors in the medium,

evaluated by the device and monitored for overshoot or

undershoot. When the threshold values are reached, the output

relay switches on or off depending on the setting.

■Technical specifications

1) 2-wire connection of resistance sensors with wire jumper between T2 and T3.
