Relé térmico TR640IP

Temperature Relays TR640IP monitor up to 6 sensors for up to 4 limits. Different sensors can be connected at the same time, e.g. Pt 100 (RTD) and PTC-thermistors. Typical applications are monitoring of motors, generators or transformers. An other application is the use as a 2- or more step-controller with additional monitoring of over- or undertemperature or monitoring of differences in temperatures of 2 sensors.

Preset programs allow easy setting e.g. monitoring of transformers with/without monitoring of temperature of core or with/ without controlling a ventilator.

Operation can be made at the device or with a standard browser via ethernet.
