VL-MR-03 — Digital Temperature Control Relay
The temperature control relay is a precision instrument for measuring and controlling temperature. It allows users to set the desired temperature range and control mode, making it ideal for maintaining constant temperatures in various applications.
It is suitable for industrial control, exhaust systems, electric heating equipment, warehouses, and other environments requiring reliable temperature management.
Key features include a wide working voltage range (AC/DC 24–240V), PTC platinum resistance sensing with delay and open/short circuit detection, real-time LED status indication, and temperature monitoring from -20°C to 80°C. Its compact 18mm width supports standard 35mm DIN rail installation, ensuring easy integration into control panels and cabinets.
