The LU-926M02(04)Y two-channel (four-channel) PID control module is a high-performance, high-reliability intelligent industrial controller built on an entirely new design concept. It is designed for the regulation and control of temperature, flow, pressure and level in semiconductor, photovoltaic, light industrial machinery, ovens, test equipment, refrigeration/heating equipment and similar applications. It is widely used in the semiconductor, photovoltaic, chemical, ceramics, metallurgy, petrochemical and heat treatment industries.

Main features:

Equipped with an advanced ARM processor, it offers fast processing speed, simple interface circuitry, and high reliability and stability.

It covers signals from thermocouples and RTDs of all common graduation types as well as standard voltage and standard current signals; the fast and accurate nonlinear correction algorithm ensures the accuracy of digital sampling.

Multiple control modes are available for free selection. The smart control mode combines fuzzy theory with conventional PID control, giving the control process fast response, small overshoot and high steady-state accuracy. It is particularly effective for objects with large pure lag that are difficult to control with conventional PID. The control algorithm includes a one-key auto-tuning function.

Comprehensive alarm outputs with 4 alarm registers that can be freely combined.

Dual-row 4-digit LED display for simple and easy human-machine interaction.

Plug-and-play modular structure with a wide range of output specifications to meet various application requirements.

Standard RS485 communication with the standard MODBUS communication protocol for high versatility and reliability.

Excellent immunity to interference; complies with industrial level-3 and above EMC test requirements.
