Memory-type Temperature Controllers

I. Overview
  LU-927M smart position proportion controller (valve position control) is a high-performance, high-reliability intelligent industrial controller adopting a brand-new design concept. It is mainly used for temperature control of kilns, can eliminate the need for a servo amplifier to directly drive the actuator, and is widely used in chemical, ceramics, glass and other industries.
Main features:
  It adopts an advanced ARM processor, featuring fast processing speed, simple interface components, and high reliability and stability. It covers signals such as thermocouples of various commonly used graduation numbers, RTDs, standard voltage and standard current, and its fast and accurate nonlinear correction algorithm ensures the accuracy of digital sampling. It is compatible with various valve position feedback signals, including standard voltage, standard current and three-wire potentiometer. It also has a virtual valve position feedback function, eliminating the need to connect a valve position feedback signal and automatically tracking the valve position status through relevant valve position parameter settings.
  Multiple control modes are freely selectable; among them, the intelligent regulation control adopts a control mode combining fuzzy theory and traditional PID control, so that the control process has the advantages of fast response, small overshoot and high steady-state accuracy, and has an obvious control effect especially on objects with large pure lag that are difficult to control by conventional PID. The control algorithm has an auto-tuning function. There are abundant setpoint modes, with two setpoint registers and functions such as external setpoint and event-triggered setpoint switching. It has valve position dead band and control dead band functions, and the dead band range can be set via register. The unique control process memory function can store 1024 points of control process memory data, and the memory modes include PV and PV+MV memory. The memory interval is adjustable from 1 to 60 seconds. Users can quickly browse by one-key operation, and the memory data is automatically refreshed according to the browsing time requirement. This function can quickly analyze the control effect and facilitate control maintenance. Rich alarm outputs: 4 groups of alarm registers can be freely combined and freely defined to any physical output interface. Through the alarm source and transmitter source parameter settings, the difference calculation alarm or difference calculation transmitter function can be realized. Dual-row 4-digit digital tube plus 20-line light column display, human-machine interaction operation, simple and easy to use. Plug-and-play modular structure and rich output specifications meet various application requirements. It adopts the standard MODBUS communication protocol, with strong versatility and high reliability. Strong anti-interference performance, passing the industrial level-3 electromagnetic compatibility test requirements
