The 3RS10, 3RS20 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 industry or electroplating
• Controlling equipment and machines such as heating, climate and ventilation systems, solar collectors, heat pumps or warm water supplies
• Motor, bearing and gear oil monitoring
• Monitoring of coolants
