Waveshare Industrial Modbus RTU 8-ch Relay Module with RS485 Interface Multi Isolation Protection Circuits Comes with an ABS Enclosure

Materiale di contatto: abs
Tipo di contatto: Normalmente aperto
Corrente nominale: 10 Ampere
Marchio: Waveshare
Modalità operativa: Automatico

- 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 ADI 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 the relay from being interfered by high-voltage circuit.
- 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.
