Hongrun NHR-1300A Intelligent Fuzzy Self tuning PID Regulator: The Omnipotent Center for Industrial Control

1Variable frequency PID controllerProduct positioning and core values:

Hongrun NHR-1300A is a high-precision, adaptive, and multi scenario compatible industrial grade intelligent PID controller designed for precise control of complex parameters such as temperature, pressure, and flow rate. Through the fuzzy PID self-tuning algorithm, 33 types of full signal compatibility, multi-mode output, and intelligent communication functions, this regulator can achieve closed-loop control and optimization of industrial equipment, and is widely used in fields such as plastic machinery, food processing, pharmaceutical sterilization, and constant pressure water supply. It is the core control unit of industrial automation systems.

2、 Core functions and technological highlights:

Fuzzy PID self-tuning and intelligent control

Adaptive algorithm: Built in fuzzy PID control module, which can automatically optimize PID parameters (proportional, integral, derivative) based on the characteristics of the controlled object, achieving precise control without manual intervention. For different types of controlled objects such as temperature and pressure, the algorithm can automatically match parameters, with a control accuracy of ± 0.5 ℃ and a response speed improvement of over 30%.

Dual mode control: supports two control modes: "lagging large system" (such as industrial furnace heating) and "fast response system" (such as pressure/flow regulation), adapting to different scene requirements through parameter switching, and avoiding overshoot or overshoot problems caused by fixed parameters in traditional PID.

Self tuning function: After starting self tuning, the system automatically runs for two cycles (temperature fluctuates twice above and below the set value), calculates PID parameters automatically, and stabilizes the control effect after tuning. Modifying the set value does not require re tuning.

Full signal compatibility and high-precision measurement

33 input types: Supports thermocouple (12 types including K/E/S), thermistor (8 types including Pt100/Cu50), voltage (0-10V), current (4-20mA), and linear resistor input, covering more than 95% of sensor types in industrial sites, with a measurement accuracy of 0.3% FS

Resolution adjustable: The resolution of the thermistor/thermocouple signal can be switched (1 ℃ or 0.1 ℃), and the cold end compensation error under high temperature environment is ≤± 0.5 ℃, meeting the full scene requirements from basic monitoring to precision control.

Multi mode output and flexible configuration

Control output type: Supports 4-20mA/0-10V analog output, relay contact output, single-phase thyristor zero crossing trigger pulse output, and solid-state relay drive voltage output, suitable for various actuators such as heating rods, regulating valves, and frequency converters.

Alarm function: Supports upper and lower limit alarms, deviation alarms, and disconnection alarms, with LED light indicators, and can be linked to external devices for emergency response.

Modular design: 35mm rail card installation, compact size (160 × 80 × 110mm), supports live terminal insertion and removal, and is easy to maintain.

Industrial grade reliability and anti-interference capability

Full isolation protection: Input/output/power tripartite optoelectronic isolation, anti-interference level up to industrial level three (EMC standard), can operate stably in environments with -10 ℃~50 ℃ and humidity ≤ 85% RH.

Wide voltage power supply: Supports dual power input of AC100-240V or DC20-29V, with built-in DC24V feed output, simplifying on-site wiring design.

Intelligent Communication and Data Management

Remote monitoring: RS485 communication supports Modbus RTU protocol and can seamlessly integrate with PLC and DCS systems to achieve remote parameter adjustment and data acquisition. The communication rate is ≤ 9.6kbps and the transmission distance is ≤ 1000 meters.

Data traceability: An optional RS232C printing interface is available, which supports manual printing, timed printing, and alarm printing, meeting the data traceability requirements of Industry 4.0.
