Monitoring Relays
3RS10, 3RS11 Temperature Monitoring Relays
Relays, digitally adjustable to DIN 3440
■ Overview
The 3RS10/3RS11 temperature monitoring relays can be used
for measuring temperatures in solid, liquid and gas media. The
temperature is sensed by the sensor in the medium, evaluated
by the device and monitored for overshoot or undershoot or for
staying within an operating range (window function).
■ Technical specifications
The 3RS10 40, 3RS20 40, 3RS11 40 and 3RS21 40 relays
comply with the requirements of DIN 3440 as temperature
monitors; the 3RS10 42 and 3RS11 42 relays comply with the
requirements of DIN 3440 as temperature limiters. The relays are
also an excellent alternative to temperature controls in the low-
end performance range (2 or 3-point closed-loop control).
