- 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.
- Measuring input 1x Pt 100 (RTD)/ 3-wire
- Measuring ranges selectable:
+ -10...+40/ 0...100/ 0...200 °C
