H-TRONIC HTS 1000 DIN Rail Temperature Switch -99°C to +850°C 1114690

Monitoring and controlling temperature in industrial and building automation often requires a reliable, DIN-rail mounted device that can handle a wide range of sensor inputs and switching loads. The H-TRONIC HTS 1000 addresses this need with a precise two-point controller for Pt100/Pt1000 sensors, offering a measuring range from -99°C to +850°C and a 10A relay output.

Who is it for

This temperature switch is intended for electricians, panel builders, and maintenance technicians who need to integrate temperature-based switching into control cabinets. It suits heating, cooling, and alarm applications where a robust DIN-rail module is required.

Tips

For accurate measurements, use a 3-wire Pt100 sensor to compensate for lead resistance. Set the hysteresis according to the process tolerance to avoid frequent relay cycling. Ensure the supply voltage matches 230V AC before wiring.
