Overview
Industrial 6-Channel Relay Module For Raspberry Pi Zero, 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, and needs no extra power supply for the isolated terminal.
- Onboard photocoupler isolation, prevents interference from external high-voltage circuit connected to the relay.
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses 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, and 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.
