Ziehl TR640IP - T224390 Temperature Relay For Pt100/1000, Ptc

The TR640IP temperature relay monitors up to six sensors simultaneously for up to four limit values. Different sensor types, such as PTC thermistors and Pt100 sensors, can be connected and evaluated. Applications include monitoring motors, generators, and transformers. The device is also suitable for use as a 2- or 3-point controller with additional alarms for over/under temperature, as a differential temperature monitor, and as a temperature controller.
