Connection

The thermologist on the right has a set of sockets for power and sensor connections. Below is a description of the sockets.

  • RS485 is used to connect to a Modbus master, i.e. to an IoT gateway, computer or PLC. 
  • Push buttons are used to configure Thermolog and change the way the danyuch is displayed
  • In place of the digital sensor, depending on the Thermolog version, either a temperature sensor or a temperature and humidity sensor is connected.
  • The Alert output is connected to either an optional sound or a sound/visual signaling device. The circuit is in NO/NC form and can control 230V mains voltage up to a maximum of 3A.
  • Thermokuple input is adapted to 2-wire PT100 only in the version of Thermolog that supports this sensor.
