TSZ2 and TSZ2H temperature switches

Pt 100, Ni 1000

These temperature switches 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. the switches consist of a plastic box carrying control buttons, display, signalling diodes, terminals for connection the temperature sensing element and power supply and terminal board for connection the output relay contacts. The plastic box is made of ABS material, terminal board ingress protection meets the requirements of IP 20 according to EN 60 529 standard.

Supply voltage of the switches is 7 to 36 V DC or 230 V AC (by the type). Two temperature sensing elements on the base of Pt (Pt 1000/3850) or on the base of Ni (Ni 1000/6180) 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. The switch can be used in 5 different modes:

Mode no. 1: the switch operates as a single controller which switches the first relay by the set temperature interval and the second relay is switched at the exceeding set emergency temperature (only one sensing element is used)

Mode no. 2: the switch operates as a single controller which switches each relay by the set temperature interval (only one sensing element is used)

Mode no. 3: the switch operates as a double controller, it means that each relay is controlled by the temperature of one sensing element

Mode no. 4: the switch operates as a diff erential controller which switches on the base of temperature difference of two sensing elements (analogous to mode no. 1)

Mode no. 5: the switch operates as a diff erential controller which switches on the base of temperature difference of two sensing elements (analogous to mode no. 2)

The switches are intended for assembly to the DIN slat. The temperature range of the switch apllications depends on used temperature sensing element type (for example for the sensor in the TG8 case the range is -30 to 200 °C). Maximum operating temperature range of the switch is -50 to 250 °C. The switches are intended for operating in a chemically non-aggressive environment.
