PT100 thermostat with relay, adjustable switching point and hysteresis, with OLED display
Article number PR515x505
The PR515x505 measures the temperature with a PT100 sensor in a 2-, 3- or 4-wire connection and switches a relay contact at a set switching point. The hysteresis determines how many degrees the temperature must drop back before the relay switches again, so a heater, cooler or fan does not keep switching on and off. You choose whether the relay switches on above or below the switching point. The OLED display shows the current temperature and the state of the relay.
- Supply 12 and 24 V DC, operating range 11 to 30 V DC
- Input PT100, 2-, 3- or 4-wire
- Output relay contact (normally open)

Setup
- Connect the supply, the PT100 and the relay contact according to the wiring diagram supplied with the module.
- On the display, set the switching point and the hysteresis, and choose whether the relay switches on above or below the switching point.
- Check the temperature and the relay state on the display and store with SAVE.
Application
- Switching on a heater or frost protection below a set temperature
- Switching on a fan or cooling above a set temperature
- Raising an alarm at too high an oil or coolant temperature
PR515 series: controllers and converters with OLED display
The modules in the PR515 series have an OLED display and push buttons, so they can be set up without a computer and show the current values of inputs and outputs. They run on 12 and 24 V DC systems. Most versions can be extended on request, for example with an extra relay output, a PWM output, a bus connection (CAN bus or Modbus) or a different sensor input.
