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). 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).
Benefits
• Very simple operation without complicated menu selections
• Certification to DIN 3440
• All devices are available alternatively with spring-loaded
• 2 or 3-point closed-loop control can be configured quickly
Application
The 3RS10 40, 3RS10 42, 3RS11 40, 3RS11 42, 3RS20 40 and
3RS21 40 temperature monitoring relays can be used in almost
any application in which temperature overshoot or undershoot is
not permitted, e.g. in the monitoring of set temperature limits and
the output of alarm messages for:
• Plant and environment protection
• Temperature limits for process variables e.g. in the packaging
• Temperature limits for district heating plants
• Exhaust temperature monitoring
• Controlling equipment and machines such as heating, climate
• Motor, bearing and gear oil monitoring
• Monitoring of coolants

The short-circuit and open-circuit detection as well as the
measuring range is limited, depending on the sensor type.
