Raspberry Pi Zero WH RS485/CAN Industrial 6-ch Relay Module with Isolated Protections(US Plug)
Features：
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)
Specifications：
OPERATING VOLTAGE: 7V~36V (industrial input voltage compatible)
COMMUNICATION PROTOCOL: RS485, CAN
RELAY CHANNEL: 6CH
CONTACT FORM: 1NO 1NC
