Functions Built-in sensor for temperature measurement and real-time display RS485 Modbus RTU communication Displays current loop temperature and control hysteresis; activates the heating cable when the temperature is below the set value and deactivates it when the temperature is above the set value. Features include a viewing window and external operation buttons. Parameters can be set and modified in real time. Displays current loop voltage and current values. Can control self-limiting temperature heating cables, constant power heating cables, and armored MILC heating cables on-site. Detects sensor faults. Closes the loop when the temperature is above the set value and operates the loop when the temperature is below the set value. Relay Output Pulse start, reducing starting current.
