Description TR400:

The Pt 100 thermostat TR400 is a temperature controller and monitors up to 4 Pt 100 sensors at the same time. 4 switching points and 4 relays permit almost any combination of switching action. It also can select the highest temperature of a group of2,  3 or 4 sensors. The temperatures of two sensors or groups of sensors can be issued to 2 analog outputs i.e. for remote displays or further evaluation. Programming is very variable and simple.
Due to the fact that 4 type Pt 100 sensors can be connected, the unit is especially suitable for temperature monitoring wherever up to 4 different measuring points must be monitored simultaneously:

  • motors and generators with simultaneous monitoring of bearings and coolant.
  • transformers with additional monitoring of the core temperature also.
  • power machines and plants

Overview of functions

  • Measuring and monitoring range -199 ... +800 °C
  • 4 sensor inputs with 2- or 3-wire connection
  • 4 relay outputs K1 to K4 with change-over contact
  • Sensor Error Relay K7 monitors sensor break or sensor short circuit as well as an
  • interruption of the power-supply.
  • 2 analog outputs, 0/4...20 mA und 0/2...10 V, with individual scaling.
  • Universal power supply AC/DC 24-240 V
  • Terminal for USB-Stick for up- and downloads of sets of parameters and for firmware- updates
  • Accessory: Installation frame ER8 for panel mount
  • Alternative: Temperature Relay Type TR660IP

Temperature Relay Type TR660IP
Version: with analog output

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.If the evaluation "2 out of x" is activated with several connected sensors, an alarm is only triggered when the limit value is exceeded in 2 sensors. This prevents false alarms due to a fault in one sensor. 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 possible7 alarms / relay outputsalarm 2 of x = alarm only when limit is exceeded in min. 2 sensorsmonitoring of difference of temperaturesmonitoring of rate of change of temperaturelogging of temperatures and historypreset programs for protection of motors, transformers and moreinterface ethernet TCP/IP, values available via modbus TCPprogramming with browser via TCP/IP or with joystick at devicecoloured LED display for clear display of temperatures and states of alarmsuniversal power supply AC/DC 24-270 VAccessory: Installation frame ER8 for panel mountTR660IP RS485:  interface RS485 (modbus RTU)TR660IP analog:  4 analog outputs 2x 0/4 - 20 mA and 2x 0/2 - 10 V, isolated from sensor inputs, individually programmable.
