waveshare Industrial Modbus RTU 8-ch Relay Module with RS485 Interface Multi Isolation Protection Circuits, 7~36V Power Supply, Support Win7/8/8.1/10/11,Linux, Android,etc.

About this item RS485 Communication: Configurable device address (1~255), multi devices can be cascaded on RS485 bus. Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit. Adopts dedicated relay driver chip, with built-in flyback diode protection, for stronger and more stable driving ability. Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection.
