4-Channel Computer Serial Port Relay Module with Indicator USB Relay Electronic Converter Module 5V for Smart Home Control

4 Channel USB Relay Electronic Converter Module with Indicator Computer USB Control Switch Relay Module 5V for Smart Home Control Features: 1.Versatile and Convenient: Easy control of 4 independent relays through a PC or microcontroller, providing flexibility for various applications. This USB control relay module features MICRO USB socket and serial communication for seamless connection with PCs and microcontrollers. Normal operating voltage of 5V ensures compatibility with standard power sources. 2.Independent or Simultaneous Control: Enjoy the freedom to activate each intelligent control switch module independently or combine them for simultaneous operation, providing versatility in controlling multiple devices. 3.Seamless Communication: Effortlessly communicate with other devices using the computer serial port relay module s serial port, allowing for efficient integration into existing systems or setups. 4.Efficient Data Control: Each byte received through the serial port directly controls the on/off state of each smart control switch module, simplifying the control process with a clear representation of relay status (0 for on, 1 for off). For I1CSE012A (4-channel), only the lower 4 bits of data are effective, disregarding other bits for control purposes. 5.Comprehensive Functionality: This USB serial port control relay module offers a comprehensive range of functions suitable for various scenarios, ensuring it meets different demands effortlessly. With its powerful performance, reliability with circuit protection, and cost-effectiveness, it is the preferred choice for electronics enthusiasts looking for quality and affordability. Specification: Origin: Mainland China Type: Module Condition: New Product Description: This module is a 4-channel relay (ICSE012A). 1. The module is a 4-channel relay (ICSE012A), which is controlled by the upper computer. 2. Adopting MICRO USB female connector and serial port to communicate with the outside world. 3. It is convenient to connect the module with PC and microcontroller, and the normal working voltage is 5V. 4. Each relay can be turned on independently or at the same time. 5. Through the serial port can directly communicate with other devices. 6. Each byte of data received by the module will directly control the start and stop of each relay. 7. Each bit of data controls a relay ( 0 means start, 1 means stop). 8. For I1CSE012A (4-way), only the lower 4 bits of data are valid, other bits of data do not control. Note: Please pay attention to the wiring, do not connect the wrong. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement.
