Industrial 6-Channel Relay Module

Designed for Raspberry Pi Zero WH

RS485/CAN bus, power supply isolation & photocoupler isolation

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 proof 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)
