Waveshare Industrial Modbus RTU 8-Ch Relay Module (B) with RS485 Interface, Multi Isolation Protection Circuits, 7~36V Power Supply

Materiale di contatto: Rame
Corrente nominale: 1E+1 Ampere
Marchio: Waveshare
Modalità operativa: Automatico
Tensione bobina: 7 Volt (CC)

- 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. 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
