The EWM151-2G4T10S/SX series wireless synchronous transmission module is designed to solve the challenges of upgrading traditional wired switches. Based on the 2.4GHz band, it supports 4-channel input/4-channel output bidirectional synchronization, with a fastest response time of 30 milliseconds and a transmission distance of up to 300 meters in open environments. It offers both automatic and manual pairing modes for immediate use. The module features an industrial-grade design and supports a wide operating temperature range of -40℃ to +85°C, making it an ideal choice for wireless upgrades in smart homes, industrial control, and other fields.
In smart home renovations and industrial automation upgrades, traditional wired switch solutions suffer from inherent pain points such as cumbersome wiring, difficult retrofitting, and poor flexibility. Meanwhile, many wireless solutions on the market suffer from high latency, complex pairing, short transmission distances, and insufficient stability, resulting in a poor user experience. The EWM151-2G4T10S/SX series wireless synchronous transmission module, with its core features of “ultra-low latency, long range, plug-and-play functionality, and industrial reliability,” provides a mature and stable wireless switch solution, facilitating rapid project implementation.

Six core advantages to solve the challenges of wireless control
- Ultra-fast response, latency as low as 30 milliseconds
From input at one end to output at the other, the fastest response time is only 30 milliseconds.
Suitable for control scenarios with high real-time requirements, such as lighting, motor start/stop, etc.
- Powerful radio frequency, 300-meter transmission range in open environments
Operating frequency band: 2.4GHz ISM band (2400~2480MHz)
Transmit power: 10dBm (maximum, software adjustable)
Receiver sensitivity: -99dBm
Communication distance up to 300 meters in open environments
- Bidirectional Synchronization, Flexible Control of 4 Inputs and Outputs
The status of the 4 DI (input) channels of module A can be synchronized in real time to the 4 DO (output) channels of module B. Conversely, the status of the inputs and outputs can be synchronized, achieving bidirectional, equal synchronous control. Simultaneous operation from both sides is supported, with all channels responding independently and synchronously.
- Two Pairing Methods: Convenience and Flexibility Combined
Automatic Pairing (Recommended)
Operation: Press the KEY button on both modules for 2 seconds.
Features: Completes automatically within 30 seconds, no additional tools required, minimalist experience.
Manual Pairing
Operation: Write the address of the other module via serial port AT commands.
Features: Suitable for scenarios requiring fixed pairing relationships and mass production.
- AT Command Support, Effortless Control of Function Parameters
Provides a rich set of AT commands, configurable via UART serial port.
Can query/set: transmit power, local address, target address, operating mode, etc.
Can perform: reboot, factory reset, firmware upgrade, and other operations.
- Typical Application Scenarios
Smart Home: Wireless light switches, curtain controllers, smart sockets.
Industrial Control: Remote equipment start/stop, status indication, safety interlocks.
Smart Agriculture: Irrigation valve control, greenhouse curtain machine control.
Smart Buildings: Corridor lighting control, conference room equipment power management.
Security Alarms: Wireless emergency buttons, door and window magnetic linkage.
- Summary
The EWM151-2G4T10S/SX is more than just a wireless module; it’s a ready-to-use, stable, and reliable wireless switch solution. It greatly simplifies the “wired to wireless” conversion process, lowering the development threshold and deployment costs. Whether you’re looking for a wireless solution for your smart home or need to add remote control functionality to industrial equipment, it’s worth considering.
