Modbus RTU 8/16/32-channel RS485 Relay Module Isolation Protection Circuits

  Features：This series of products is a relay module controlled by an industrial RS485 interface. The number of relays can be 8/16/32, using Modbus RTU protocol, with built-in power isolation, ADI magnetic coupling isolation, self-recovery fuse and TVS protection circuits, ABS DIN rail shell design. This product is easy to operate, has the characteristics of fast communication speed, stability, reliability, safety, etc., and can be applied to various industrial control equipment or applications with high communication requirements.Support setting the device address (1~255), in order to cascade multiple devices through the RS485 bus, with flash open and flash off functions, and the onboard integrated power isolation can be automatically closed by commanding the relay to open for a period of time, which can provide stable Isolation voltage, no additional power supply is required for the isolation end. Onboard integrated ADI magnetic coupling isolation can perform signal isolation, with h
