Industrial 6-Channel Relay Module for Raspberry Pi Zero SPI CAN RS485

Download RPi Zero Relay Module User Guide

This 6-Channel Industrial Relay Module has been designed to work with Raspberry Pi Zero WH. The module supports RS485 half-duplex communication through auto RX / TX Switch, SP3485, and UART control. This industrial relay module also supports CAN (half-duplex) communication through SPI control and MCP2515 + SN65HVD230 solution. The module has power supply isolation and photocoupler features.

Features of Industrial Relay Module for Raspberry Pi Zero

• RS485 Communication (Half-Duplex): Uses auto RX / TX Switch, UART control, and SP3485
• CAN Communication (Half-Duplex): Uses SPI control and MCP2515 + SN65HVD230 solution
• Photocoupler Isolation Onboard: Resists high voltage interference from the externally connected circuit
• Power Isolation for Stable Isolated Voltage: Unibody power supply isolation onboard | Isolated terminals do not need an extra power supply
• Transient Voltage Suppressor (TVS) Onboard: Suppresses transient spike voltage and surge voltage in the circuit | Anti-electrostatic and lightning proof
• ABS Box: Easy to install ABS protection box | Rail Mount support | Safe to use
• Contact Rating: ≤10A 30V DC or ≤10A 250V AC
• Protection Diodes and Resettable Fuses Onboard: Ensure stable voltage / currency output | prevent over voltage / current | shock resistance
