Memory-type Temperature Controllers

   The LU-921M two-loop on/off controller is a high-performance, high-reliability intelligent industrial controller adopting a completely new design concept. It is widely used in automatic control systems for temperature, flow, pressure, level and other parameters in chemical, ceramic, metallurgy, petrochemical, heat treatment and other industries.
Main features:
It adopts an advanced ARM processor, providing fast processing speed, simple interface components, and high reliability and stability. Two independent loop inputs cover thermocouples, RTDs, standard voltage, standard current and other signals of various common graduations, and the fast and accurate non-linear correction algorithm ensures the accuracy of digital sampling. The unique control-process memory function allows 1024 points of control-process memory data to be set, with two memory modes: PV1 and PV1+PV2. The memory interval is adjustable from 1 to 60 seconds. Users can browse quickly with one-key operation, and the memory data is refreshed automatically according to the browsing time requirement. Abundant alarm outputs: 4 groups of alarm registers can be freely combined and freely assigned to any physical output interface. Through the alarm source and transmitter source parameter settings, difference-value calculation alarm or difference-value calculation transmitter output can be realized. Dual-row 4-digit digital tube display and human-machine interaction make operation simple and easy. The plug-and-play modular structure and abundant output specifications meet various application requirements. It adopts the standard MODBUS communication protocol, featuring high universality and high reliability. Strong anti-interference performance; it meets the requirements of industrial level-3 EMC testing.
