Features:

Support setting device address (1~255) to cascade multiple devices via RS485 bus

With flash on and flash off function, you can bring parameters in the command, the operation relay will turn off automatically after a period of time

Onboard integrated power supply isolation can provide stable isolation voltage without additional power supply at the isolation end

Onboard integrated ADI magnetic coupling isolation, signal isolation, high reliability, strong anti-interference, low power consumption

Onboard TVS (transient voltage suppression tube), which can effectively suppress surge voltage and transient spike voltage in the circuit, lightning protection and static electricity protection

Onboard optocoupler isolation to avoid interference from relay high voltage circuits

Onboard anti-reverse connection circuit to avoid reverse connection of the positive and negative electrodes

Adopt high-quality relays, allowing access to load: ≤10A 250V AC or ≤10A 30V DC

Guide rail type ABS plastic shell, easy to install and use, more secure with shell

Three external LED indicators for easy viewing of MCU status and signal sending and receiving status

Parameter:

Power supply voltage: 5V

Communication interface: RS485

Communication baud rate: 4800, 9600, 19200, 38400, 57600, 115200, 128000, 256000

Default communication format: 9600, N, 8, 1

Number of relays: 8

Contact type: one normally open and one normally closed

Communication protocol: Standard Modbus RTU protocol

RS485 address setting: 1~255

RS485 interface protection: provide 600W lightning protection, surge and 15KV static protection (reserved 120R balanced resistance pad)

Indicator light:

STA: MCU indicator, flashes when the MCU is working normally

TXD: send indicator light, light on when sending data

RXD: Receive indicator, the light is on when receiving data

Package includes:

1 x 8-way relay module

RS485 communication:

Support setting device address (1~255), multiple devices can be cascaded through RS485 bus

When there are many cascade devices and the communication distance is long, RS485 repeater must be added according to the actual application
