32-channel RS485 Interface Relay Module Multiple Isolation Protection Circuits

Modbus RTU 32-channel RS485 interface relay module with multiple 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.
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.
