LU-960M Intelligent Program PID Controller
The LU-960M intelligent program controller is widely used in automatic temperature, flow, pressure and level control systems in the chemical, ceramics, light industry, metallurgy, petrochemical and heat treatment industries.
I. Overview
Built on the LU-660M smart program controller, the LU-960M smart program controller further improves noise immunity and overall performance through a modular structure, EMI suppression, and other technologies; combined with the advanced fuzzy PID control method, its functions and performance are increasingly complete.
The LU-960M is compatible with various thermocouples, RTDs, and standard input signals. It offers multiple output modes and control modes and can set program control curves of 20 to 200 segments, making it suitable for systems requiring high-accuracy multi-segment ramp/soak program heating/cooling control.
The LU-960M combines fuzzy theory with conventional PID control, giving the control process fast response, small overshoot, and high accuracy. It provides on/off control, bumpless manual/automatic switching, and auto-tuning. It adopts a dual 4-digit LED display that can show the measured value, setpoint, and running time simultaneously. The hardware adopts a WATCHDOG circuit, and the software adopts redundancy, trap, and other noise-immunity techniques. It has two programmable control event outputs. The LU-960M smart program controller is widely used in automatic control systems for temperature, flow, pressure, and level in chemical, ceramic, light industry, metallurgy, petrochemical, heat treatment, and other industries.
