Waveshare Industrial Modbus RTU 8-ch Relay Module Features
-
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 TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, llgthningproof & anti-electrostatic. Onboard Optocoupler isolation, prevent interference from external high-voltage circuit connected to the relay
-
Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection. High quality relay, contact rating: ≤10A 250VAC/30VDC
-
Rail-mounted ABS plastic enclosure, easy to install, safe to use. 3 LEDs for indicating the MCU status and signal transceiving status
