Industrial-grade 8-channel RS485 magnetic latching relay module Modbus RTU protocol Guide rail housing

Product features

This product is an industrial-grade 8-channel magnetic latching relay module controlled by an RS485 interface. The state of the relay remains unchanged after power loss. It adopts the Modbus RTU protocol, incorporates built-in power isolation, magnetic coupling isolation, and TVS protection circuits, and features an ABS housing design. This product is easy to operate and characterized by fast, stable, reliable, and secure communication. It is suitable for various industrial control devices or applications with high communication requirements.

- Using magnetic latching relays, the state of the relay will remain unchanged after power is turned off

- Supports setting device addresses (1~255) to facilitate cascading multiple devices via the RS485 bus

- It features a flashing-on and flashing-off function, allowing the relay to be controlled by a command to open for a certain period of time and then automatically close

- Integrated on-board power isolation provides stable isolated voltage, eliminating the need for additional power supply to the isolation terminal

- Integrated on-board magnetic coupling isolation for signal isolation, high reliability, strong anti-interference, and low power consumption

- Equipped with on-board self-resetting fuses and TVS (Transient Voltage Suppressors), it can effectively suppress surge voltage and transient spike voltage in the circuit, protect against overcurrent and overvoltage, as well as lightning and static electricity

- Utilizing a dedicated magnetic latching relay drive chip, providing stronger and more stable driving capability

- On-board anti-reverse connection circuit to prevent damage to the circuit due to reversed positive and negative connections

- Utilizing high-quality relays, it allows for the connection of loads up to: ≤10A 250V AC or ≤10A 30V DC

- Guide-rail type ABS protective shell, convenient for installation and use, and safer with the shell

- Equipped with 3 external LED indicators, facilitating easy observation of MCU status and signal transmission/reception status
