RS485/CAN Bus, Power Supply Isolation & Photocoupler Isolation.

Raspberry Pi Zero is NOT included.

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, lightning proof & 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)

OPERATING VOLTAGE	7V~36V (industrial input voltage compatible)	RELAY CHANNEL	6 ch
COMMUNICATION PROTOCOL	RS485, CAN	CONTACT FORM	1NO 1NC
