Pt 100-Temperature relays Type TR111V

Pt 100 Temperature-Relay, 1 sensor Pt 100, 3-wire, 1 Limit, 3 measuring ranges

Pt 100-Temperature relays Type TR111V

Part number

-10...+200 °C
0...400 °C

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.
