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

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
Relay wiring
The device has a relay with a contact capacity of 10A 250V AC or 10A 30V DC
Can directly control household 220V AC equipment, can also control DC equipment below 30V
