Thermisches Relais TR660IP.

Temperature Relays TR660IP monitor up to 6 sensors for up to 7 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.

• 6 inputs for sensors Pt 100, Pt 1000 and PTC, mixed sensors possible
• 7 alarms / relay outputs
• alarm 2 of x = alarm only when limit is exceeded in min. 2 sensors
• monitoring of difference of temperatures
• monitoring of rate of change of temperature
• logging of temperatures and history
• preset programs for protection of motors, transformers and more
• interface ethernet TCP/IP, vlues available via modbus TCP
• programming with browser via TCP/IP or with joystick at device
• coloured LED display for clear display of temperatures and states of alarms
• universal power supply AC/DC 24-270 V
