Top hat rail temperature switch HTS 1000 The top-hat rail temperature switch HTS 1000 can measure the current temperature in the range from -99 degrees Celsius to +850 degrees Celsius (depending on the sensor used) in various media (air, water, oil, etc.) with the aid of a PT1000 temperature sensor. Based on this measured value, a variety of temperature controls can be realized using 3 different functions (thermometer, cooling and heating). Various consumers (e.g. fan heaters, air conditioning systems, alarm systems, etc.) can be controlled automatically and manually via two integrated, potential-free relays. A clear OLED display provides constant (or time-limited) information about the current temperature, selected function and current switching status of the integrated relays.
