Temperature switches TSZ4H

These temperature switches KTSZ4H with display are designed for using as two--state controllers (on/off type control). They compare the temperature set-point with the actual temperature value and enable switching the galvanically separated (electrically insulated) contacts of a connected relay when the set temperature is reached. Supply voltage of the switches is 10 to 33 V DC or 9 to 24 V AC (by the type). Two temperature sensing elements can be connected to the switches. The display indicates the present value of the measuring temperature during measure process. Setting of individual parameters is executed by two control buttons.
