Overview
The 3RS10 41 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 signal
evaluator can evaluate up to 3 resistance sensors at the same
time and is specially designed for monitoring motor windings
and bearings.
Benefits
• Very simple operation without complicated menu selections
• Space-saving with 45 mm width
• All devices are available alternatively with spring-loaded
• 2 or 3-point closed-loop control can be configured quickly

Application
The 3RS10 41 temperature monitoring relays can be used in
almost any application in which several temperatures have to be
monitored simultaneously for overshoot or undershoot or within
a range.
Monitoring of set temperature limits and output of alarm
messages for:
• Plant and environment protection
• Temperature limits for process variables e.g. in the packaging
• 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.
