Description
Industrial 6-ch Relay Module for Raspberry Pi Zero, RS485/CAN, Isolated
RS485/CAN Bus, Power Supply Isolation & Photocoupler Isolation.
Raspberry Pi Zero is NOT included.
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, 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)
