Dual Independent Control Loops
Separate PID regulation for Channel A and Channel B, supporting simultaneous monitoring and control of two distinct thermal zones without signal interference, ideal for dual-temperature processes like extrusion lines and industrial furnaces.
High-Accuracy Self-Tuning PID Control
The auto-tune function eliminates complex manual parameter calibration; control accuracy reaches ±0.3% full scale, minimizing temperature fluctuation to stabilize product quality and cut energy consumption.
Universal Multi-Type Input Support
Compatible with thermocouple (K, J, T, S, R, B), RTD PT100, 0–10V voltage, and 4–20mA current signals, adaptable to nearly all industrial temperature measurement sensors.
Dual Relay Output (CC Configuration)
Dual relay drive outputs for heating/cooling actuators, supporting direct control of contactors, heaters, and cooling valves; flexible matching for single-stage or dual-stage thermal systems.
RS485 Modbus RTU Communication (JURG Option)
The standard Modbus protocol enables remote data reading, parameter modification, and centralized monitoring with PLC, HMI, and SCADA systems, simplifying factory automation networking.
Clear Dual Digital Display & Intuitive Keypad
Large segmented LED screen separately shows real-time process value (PV) and setpoint value (SV) for both channels; four-button human-machine interface allows quick parameter setup without complicated manuals.
Industrial-Grade Durability & Compliance
Wide operating temperature range (-20℃ ~ 70℃), storage temperature -40℃ ~ 85℃; CE, RoHS, and UL certified, front panel IP65 dustproof and waterproof design for production floor use.
Industrial heating furnaces, batch ovens, and thermal treatment equipment
Plastic extrusion, injection molding, and blow molding machinery
Laboratory constant-temperature test chambers
Food processing, baking, and drying production lines
Semiconductor thermal processing equipment
Packaging machinery and environmental test cabinets
Dual-channel design reduces cabinet space and cuts procurement cost vs two single-loop controllers.
Plug-and-play Modbus communication lowers system integration workload.
Universal sensor input removes extra signal converter costs.
Rugged hardware and long service life reduce equipment downtime and maintenance expenses.
