Programmable temperature monitoring with RS485 interface

The temperature switches of the WTR 600 series combine robust design with digital communication and flexible parameterization. Thanks to their compact design, the devices are particularly suitable for confined installation situations and environments subject to vibration. The integrated RS485 interface with Modbus protocol allows switching points, hysteresis, and other parameters to be freely configured. In addition to the switching function, continuous temperature measurement is also possible.

For process monitoring, the devices can be integrated into higher-level systems or connected to our data loggers . For classic control tasks, our PID controllers offer a complementary solution for temperature management.

  • Compact temperature switch with screw-in thread or smooth protective fitting
  • Digital communication via RS485 (Modbus)
  • Freely adjustable switching point
  • 2-point control with definable hysteresis
  • Simultaneous temperature measurement
  • Variably adjustable immersion depth (depending on model)
