FKR-21 Switch Signal Acquisition Module

Design and Structure

• Three-terminal isolation design: Utilizes input, communication, and power three-terminal isolation conversion technology to effectively enhance system safety and stability while avoiding interference.
• Modular design: Each module provides 16 or 32 channels of switch input, facilitating convenient and quick system integration and flexible expansion based on actual needs.
• Convenient plug-and-play structure: Unique plug-and-play structural design allows for free online insertion, removal, and replacement without disassembling terminal wiring, making maintenance and replacement easy and efficient.

Performance and Functionality

• Intelligent processing capability: Equipped with a built-in microprocessor and intelligent design, offering flexible and diverse system settings.
• Anti-interference and reliability: Switch inputs and communication interfaces use optoelectronic isolation, with RS485 serial communication providing strong anti-interference capabilities and self-diagnostic functions. A single fault does not affect the monitoring of other switch acquisition modules.
• Signal processing technology: Employs software filtering technology to debounce switch inputs, with adjustable debounce time to ensure the accuracy of acquired signals.

Compatibility and Application

• Communication compatibility: Adopts the MODBUS RTU protocol, communicating with the host computer via the RS485 interface at a communication rate of 9600bps, offering good compatibility.
• Wide applicability: Can be used in conjunction with devices such as the WZCK-21 microcomputer DC monitoring system, suitable for automation systems in substations, power plants, and other applications.

The role of the switch acquisition module is to collect and upload the status and alarm signals of various distribution parts in the power system. The FKR-21 switch acquisition module uses input, communication, and power three-terminal isolation conversion methods to pick up the status and alarm signals of various distribution components in the power system. It also features RS485 serial communication functionality, enabling convenient uploading of monitoring data for various switch signals in the power system.
