Waveshare Industrial 6-Channel Relay Module for Raspberry Pi Zero WH RS485/CAN Bus Power Supply Isolation Photocoupler Isolation

Produktbeschreibung

RS485 half-duplex communication: using SP3485, UART control, auto RX/TX switch. CAN half-duplex communication: using MCP2515 + SN65HVD230 solution, SPI control Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard photocoupler isolation, prevent interference from external high-voltage circuit connected to the relay Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic Onboard resettable fuses and protection diodes, ensuring current/voltage stable output, preventing over current/voltage, better shock-resistance performance High quality relay, contact rating: ≤10A 250V AC or ≤10A 30V DC. ABS protection enclosure with rail-mount support, easy to install, safe to use. Comes with development resources and manual (wiringPi and python examples)
