SK200PRO-U: Industrial-grade Remote Wireless Switch Control, Easily Achieve One-to-Many MESH Networking

The SK200PRO-U, an industrial-grade remote wireless single-channel switch control module, integrates LoRa spread spectrum modulation technology and MESH self-organizing network functionality. It features strong driving power, excellent anti-interference capability, and multiple safety protection designs, offering efficient, stable, and flexible performance.

1. SK200PRO-U Overview

The SK200PRO-U wireless single-channel switch control module consists of a transmitter module (SK200PRO-U-TX) and a receiver module (SK200PRO-U-RX). The transmitter can select a power output of 100mW, 1W, or 5W, depending on the communication distance and environmental requirements. This module adopts LoRa spread spectrum modulation technology, providing higher receiver sensitivity (up to -132dBm) and stronger anti-interference capability, which enhances the reliability of wireless communication.

2. One-to-One and One-to-Many MESH Networking Communication Modes

One-to-One Mode: A single transmitter module (SK200PRO-U-TX) communicates with a single receiver module (SK200PRO-U-RX) in a simple and easy-to-use configuration. This mode is suitable for remote control of individual devices, such as remote switch control or access control systems.

One-to-Many Mode: A single transmitter module (SK200PRO-U-TX) communicates with multiple receiver modules (SK200PRO-RX), supporting MESH self-organizing network functionality. The receiver modules also have MESH capability, allowing wireless network communication without blind spots or distance limitations. Multiple devices can communicate simultaneously without interference, making it flexible and convenient to use. This mode is particularly suitable for industrial automation, remote control, and wireless pump control systems.

3. Strong Driving Power to Ensure Stable Long-Distance Communication

The transmitter power of the SK200PRO-U is selectable (100mW to 5W), providing sufficient signal coverage across various operating environments.

Long-Distance Transmission:
In open environments, the communication distance can reach several kilometers.

High Sensitivity Reception (-132 dBm):
Even in weak signal conditions, the module ensures reliable communication quality.

Strong Anti-Interference Capability:
The module is designed to withstand interference, maintaining stable communication in challenging environments.

4. Multiple Safety Protection Mechanisms to Ensure Long-Term Stable Operation

The SK200PRO-U integrates both hardware and software protection mechanisms to ensure the system operates reliably over long periods without failure.

Hardware and Software Anti-Freezing Protection Circuit:
The module is equipped with an internal software watchdog algorithm and hardware anti-freezing protection circuit, which can automatically recover the system in case of malfunction or freeze, preventing control failures due to prolonged operation.

2. Overcurrent, Overvoltage, and Reverse Connection Protection Circuit

The overcurrent, overvoltage, and reverse connection protection circuits automatically cut off abnormal currents, stabilize voltage fluctuations, and prevent incorrect wiring, ensuring the safe operation of the device and enhancing system reliability.

3. Electrostatic Protection and Hardware Reset Mechanism

The electrostatic protection circuit of the SK200PRO-U effectively reduces electrostatic interference in industrial environments. The hardware reset mechanism ensures the system quickly recovers to a stable state in the event of a malfunction, collectively enhancing the module's reliability and anti-interference capabilities.

5. Adjustable Parameters and Convenient Operation

Users can configure and modify the module’s internal parameters using Siwei Wireless’s PC interface. The receiver also supports wireless configuration through the transmitter, making it easier to make changes online. Multiple devices can communicate simultaneously without interference, providing flexibility and ease of use.
