Temperature Relay Type TR640IP
Sensors 4 x Pt 100, Pt 1000 or PTC thermisors, 4 limits, analog outputs or interface RS485, IP interface, operation with browser via TCP/IP.

Temperature Relays TR640IP monitor up to 4 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 two 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.
