The Pt100 thermostat TR250 monitors up to 3 sensors Pt100 (RTD), Pt1000, KTY83 KTY84 or thermistors (PTC) at the same time. Different types of sensors, e.g. Pt 100 and PTC can be monitored simultaneously. The unit is especially suitable for monitoring motors, generators and transformers. An other application is the use as a 2- or 3-step-controller with additional monitoring of over- or under-temperature. monitoring of differences in temperatures of 2 sensors or temperature controller for heat pumps.

Function

*Measuring an dmonitoring range -199...+850 °C

*Resolution 0.1 °C for measuring range –19.9...99.9 selectable

*3 relay-outputs K1 to K3 with change-over-contacts

*Universal power-supply AC/DC 24-240 V

*Easy setting *Storing of values of MIN- and MAX temperature

*Alarm counter for 3x99 alarms with display of sensor and elapsed time

*Code-lock against manipulation of settings

3 Sensor inputs:

*Pt 100 (RTD) or Pt 1000, 2- or 3-wire-connection, KTY83, KTY84

*Thermistors (PTC) each 1...6 in series

*Monitoring of short-circuit and break

Displays:

* 3 digit 7 segment display for temperature and programming

* 3 LEDs for sensors, for alarms/relays

* display °C or °F selectable, resolution 0.1 °C

Switching functions:

*3 relays

* warmest/coldest sensor switches relay

*3 LEDs for alarm/relay

*programmable for every relay:

  -hysteresis -autoreset or electronic reclosing lock

  -delay time for switching and switching back

  -operating- or closed current-mode

  -cyclic check of function

*monitoring of difference in temperature

6 preset programs:

*Motor /generator 3x Pt 100

* transformer with 3x Pt 100

* transformer with 2x PTC and 1x Pt 100

* transformer with 2x PTC / 3x PTC
