Supply KN-2250W with RS485 communication and 4-20mA analog output function

KN-2250W is a versatile indicator designed for the industrial automation field, integrating signal reception, processing, display, and data transmission. It a compact design and stable performance, suitable for real-time monitoring and status indication of parameters in various industrial control scenarios. The following details are described from multiple perspectives, including core functions technical parameters, applicable scenarios, and design details:

I. Core Functions and Performance 1. Multi-type Signal Adaptation Capability Supporting various input types such as “MULTI”, it is compatible with multiple signal sources including voltage (e.g. DC 0-10V), (e.g. 4-20mA), resistance (e.g. Pt100 thermistor), etc. It can directly connect to different of sensors or transmitters, such as temperature, pressure, flow, level, etc., without the need for additional conversion equipment, significantly enhancing its versatility in complex industrial environments. 2. Accurate Signal Output and Feedback Equipped with a 4-20mA analog output interface, it can output processed measurement values or control signals in form of continuous analog quantities to PLC, DCS, and other control systems, achieving closed-loop regulation of industrial processes. At the same time, it supports RS48 communication interfaces, adopting Modbus RTU protocol, which can be networked with multiple devices to achieve remote data collection, parameter setting, and status monitoring, meeting the centralized management needs automated production lines. 3. Intuitive Indication and Display Function As an indicator, its core function is to present monitoring parameters (e.g. temperature value pressure value) or device status (e.g. normal operation, alarm) in real-time through a clear display interface (such as LED digital tubes or indicator lights), allows operators to quickly read key information, timely judge the system operation, and reduce errors and delays in manual patrol inspection. II. Technical Parameters and Certifications - Parameters - Working Voltage: Typically DC 12-24V (refer to the product manual for specific values), compatible with commonly used industrial direct current supplies, with strong anti-voltage fluctuation capability; - Input Impedance: Varies according to the input signal type, for example, the voltage input impedance ≥0kΩ, current input impedance ≤250Ω, ensuring stability during signal transmission; - Output Accuracy: The 4-20mA analog output accuracy reach ±0.1% FS (full scale), ensuring the accuracy of signal feedback; - Communication Rate: The RS485 interface supports multiple baud rates as 9600/19200/38400/57600/115200 bps, which can flexibly set according to system requirements. - Certifications and Reliability Having passed multiple international authoritative certifications such as UKCA (UK market access certification), (EU safety certification), RoHS (environmental certification), and EAC (Eurasian Economic Union certification), it indicates that it complies with international standards in of electromagnetic compatibility (anti-interference capability), safety (anti-electric shock, fire prevention), and environmental protection (restriction of harmful substances), and can be used in multiple regions such as the EU, the UK, and Russia, and can also adapt to industrial workshop environments with multiple dust and strong electromagnetic interference. III. Stural Design and Installation - Compact Appearance: Adopting a miniaturized design, the size is usually within the standard instrument panel mounting specifications (e.g. ≤48mm), saving space in control cabinets or instrument panels, and suitable for deployment in densely installed automated systems; - Installation Method: Supporting panel installation, fixed by clips or screws, the installation process is simple, and it can ensure the sealing with the device panel, reducing the invasion of dust and moisture; - Interface: Using terminal-type wiring, clearly marked, convenient for on-site wiring and later maintenance, and reducing the probability of wiring errors

IV. Applicable Scenarios Due to its multi-signal adaptability, precise output, and stable operation, the K-2250W is widely used in: - Temperature and pressure monitoring of reactors in the chemical and pharmaceutical industries; - Level and flow indication of food production lines; - Motor speed and torque status feedback of mechanical manufacturing equipment; - Material position and conveyor speed monitoring of intelligent warehousing systems, etc Hefei Madeley Electrical Technology Co., Ltd. is an engineering service company that specializes in the sales, technical services, and training of industrial automation products and C systems.
