PID Digital Temperature Controller – TC/RTD Input, SSR / Relay / 0–10V / 4–20mA
Industrial PID temperature controller with universal sensor input, multiple control outputs, alarms, and optional RS-485 communication for precise process control.
The LC708 Series PID Digital Temperature Controller is a compact, high-accuracy controller designed for industrial temperature measurement and closed-loop control.
Supporting thermocouple (TC) and RTD inputs, the controller integrates advanced PID regulation with flexible output options including relay, SSR drive, 0–10V, and 4–20mA. This makes it suitable for direct control of heaters, solid state relays, power regulators, and analog control devices.
The controller features a high-brightness LCD display, intuitive menu configuration, and manual / automatic control switching, allowing both commissioning and operation flexibility. Optional alarm outputs, analog retransmission, and RS-485 communication enable seamless integration into PLC, SCADA, and industrial automation systems.
