PID Temperature Controller – 4–20 mA Input, Relay / SSR / Analog Output
Industrial PID temperature controller with 4–20 mA input, multiple control outputs, and high-accuracy regulation for process automation and thermal control systems.
This industrial PID temperature controller is designed for accurate and stable control of temperature and process variables using a 4–20 mA analog input. It supports multiple output options including relay, SSR drive, 0–10 V, and 4–20 mA, making it suitable for a wide range of industrial control applications.
The controller features a high-brightness LCD display, intuitive front-panel operation, and both manual and automatic control modes. With optional RS-485 communication, alarm outputs, and analog retransmission, it integrates easily into PLC, SCADA, and distributed control systems.
