RS232 Relay Module Opto 4 Channel Serial Port Control Relay Module with 8 Bit MCU SP3232

<div>Welcome to our store! We hope you have a wonderful shopping experience!</div>

<ul><li>Feature: 
1. Functionality: A relay is an electrical control device, which causes the controlled quantity in the electrical output circuit to have a predetermined step change when the change in the input quantity (excitation amount) meets the specified requirement. 
2. Interactive System: It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). 
3. Automation Ready: Usually used in automated control circuits, it is essentially an automatic switch that uses a small current to control the operating of a large current. Therefore, it plays roles such as automatic adjustment, safety guard, and circuit conversion in the circuit. 
4. 8 Bit MCU: The RS232 relay module is designed with a stable 8 bit MCU, complemented by an RS232 level communicating chip, optimizing the performance and reliability of communicating and control systems. 
5. 4 Channel Relay Module: Using the standard RTU format of RS232 communicating protocol, it can realize 4 channel input signal detection and 4 channel relay output, which can be used in digital quantity detection or power control occasions. 
Specification: 
Item Type: Relay Module 
Material: PCB 
Power Supply Voltage: 5-32V 
Communicating Protocol: Supports Standard for Modbus RTU Protocol 
Communicating Interface: RS232 Interface 
Communicating Baud Rate: 4800 9600 19200, Default 9600bps, Supports Power Off Memory 
Output Signal: Relay Switch Signal 
Device Address: Range 1-255, Default 255, Supports Power Off Memory 
Product Size: Approx. 77x64mm / 3.0x2.5in. 
Package List: 
1 x Relay Module</li></ul>
