Product description
Temperature-Relays TR111V can be used as limit-switches or 2-point controllers with high repeat accuracy. 3 measuring-ranges, adjustable hysteresis and switching delay and the choice between operating- and closed-current principle of the relay make it a very universal device.
Application: Protection from over-temperature in processes, plants and machines. Monitoring of temperatures in bearings. Controlling of temperatures in processes and plants.
