DC7-24V 4 Channel Modbus Relay Module RS232/TTL UART Interface Diode Effusion Protection Modbus RTU Format Relay Module

Features

1: Widely used

2: Communication interface: support RS232/TTL UART interface;

3: It can realize 4 input signal detection and 4 relay output, which can be used for digital quantity detection or power control occasions.

4: Easy to use

5: Communication protocol: support standard Modbus RTU protocol;

The four-way Modbus relay module is equipped with a mature and stable 8-bit MCU and RS232 level communication chip. Using standard MODBUS RTU format RS232 communication protocol, it can realize 4 input signal detection and 4 relay output, which can be used for digital quantity detection or power control occasions.

Features

1. Onboard mature and stable 8bit MCU and MAX3232 level conversion chip;

2. Communication protocol: support standard Modbus RTU protocol;

3. Communication interface: support RS232/TTL UART interface;

4. Communication baud rate: 4800/9600/19200, the default is 9600bps, and it supports power-off save;

5. Optocoupler input signal range: DC3.3-24V (this input cannot be used for relay control);

6. Output signal: relay switch signal, support manual, flash off, flash off mode, flash off/flash off delay base is 0.1S, the maximum flash off/flash off time can be set to OxFFFF*0.1S=6553.5S;

7. Device address: range 1-255, default 255, support power-off save;

8. The baud rate, input signal, relay status, and device address can be read using software/commands;

9. There are 4 5V, 10A/250V AC 10A30V DC relays onboard, which can be activated continuously for 100,000 times, with diode effusion protection, and short response time;
