Product Features

This product is an 8-way high-current relay module controlled by an industrial RS485 interface, using the Modbus RTU protocol, with built-in power isolation, ADI magnetic coupling isolation, self-recovery fuse and TVS protection circuits, and ABS rail housing design. This product is easy to operate, with fast, stable, reliable and safe communication speed, and can be applied to various industrial control equipment or applications with high communication requirements.

• Supports setting device address (1~255) to cascade multiple devices via RS485 bus
  
• With flash-on and flash-off functions, the relay can be controlled by command to automatically close after being opened for a period of time
  
• Onboard voltage regulator chip, direct plug-in 7V~36V wide voltage power supply
  
• Onboard integrated power isolation can provide stable isolation voltage, and no additional power supply is required at the isolation end
  
• Onboard integrated ADI magnetic coupling isolation for signal isolation, high reliability, strong anti-interference and low power consumption
  
• Onboard resettable fuse and TVS (transient voltage suppressor) can effectively suppress surge voltage and transient spike voltage in the circuit, prevent overcurrent and overvoltage, lightning protection and anti-static
  
• Onboard optocoupler isolation to avoid interference from relay high voltage circuits
  
• Adopting special relay driver chip, with built-in freewheeling diode protection, the driving ability is stronger and more stable
  
• Onboard anti-reverse connection circuit to prevent the positive and negative poles from being reversed and burning the circuit
  
• Adopt high-quality high-current relays, allowing access to loads: ≤30A 250V AC or ≤30A 28V DC
  
• Rail-type ABS protective housing, easy to install and use, safer with housing
  
• Three external LED indicators are provided to facilitate viewing of the MCU status and signal receiving and sending status

Product Parameters

High current terminal blocks

30A high current relay, high quality terminal block with cover, high current wiring is more convenient

Onboard multiple isolation protection circuits

Multiple protections, safer and more reliable to use

Ports and indicators

With a variety of indicator lights, it is convenient to check the working status of the module

Guide rail housing design

Rail-type ABS protective housing, easy to install and use, safer with housing

RS485 communication

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

When there are many cascaded devices and the communication distance is far, it is necessary to add RS485 repeater according to the actual application environment

The picture is for display only, this product does not include USB to RS485

Relay Wiring

The device has a relay with a contact rating of 30A 250V AC or 30A 28V DC
