Beschrijving

Informatie (ENG)

Single Modbus relay module is equipped with mature and stable 8-bit MCU and

RS485 level communication chip. RS485 communication using standard MODBUS RTU format

Communication protocol, which can realize 1 optical coupler input signal detection and 1 relay output, which can be used for digital

Word quantity detection or power control occasions.

Specs:

1. Onboard mature and stable 8bit MCU and MAX485 level conversion chip

2. Communication protocol: support standard Modbus RTU protocol

3. Communication interface: support RS485/TTL UART interface

4. Communication baud rate: 4800/9600/19200, default 9600bps, support power-off save

6. Optocoupler input signal range: DC3.3-30V (this input cannot be used for relay control)

7. Output signal: relay switch signal, support manual, flash off, flash off mode, flash off/flash

The base number of the time delay is 0.1S, and the maximum flash-off/flash-off time can be set as

0xFFFF*0.1S=65535*0.1S=6553.5S

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

9. Onboard 1 way 5V, 10A/250V AC 10A/30V DC relay, can suck continuously

100,000 times, with diode effusion protection, short response time

10. On-board relay switch indicator

11.Supply voltage: DC7-24V, with input anti-reverse connection protection
