Aplication and short description
Temperature-Relays TR 111 V 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.
Protection from over-temperature in processes, plants and machines.
Monitoring of temperatures in bearings.
Controlling of temperatures in processes and plants.
