Industrial 6-Channel Relay Module For Raspberry Pi Zero, RS485/CAN Bus, Power Supply Isolation, Photocoupler Isolation Industrial 6-Channel Relay Module

Designed for Raspberry Pi Zero WH

RS485/CAN Bus, Power Supply Isolation & Photocoupler Isolation

Features At A Glance

• 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)
