Product description

 

Site for Programming 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 of 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
