Industrial 6-Channel Relay Module for Raspberry Pi Zero
Download RPi Zero Relay Module User Guide
This is a 6-Channel Industrial Relay Module compatible with Raspberry Pi Zero WH. The module features half-duplex RS485 communication via auto RX / TX Switch, UART control, and SP3485. In addition, it also supports half-duplex CAN communication via SPI control and MCP2515 + SN65HVD230 solution. This relay module comes with Photocoupler and Power Supply Isolation features.
Features of Industrial Relay Module for Raspberry Pi Zero
- CAN Communication (Half-Duplex): Uses SPI control and MCP2515 + SN65HVD230 solution
- RS485 Communication (Half-Duplex): Uses auto RX / TX Switch, UART control, and SP3485
- Power Isolation for Stable Isolated Voltage: Unibody power supply isolation onboard | Isolated terminals do not need an extra power supply
- Photocoupler Isolation Onboard: Resists high voltage interference from the externally connected circuit
- Transient Voltage Suppressor (TVS) Onboard: Suppresses transient spike voltage and surge voltage in the circuit | Anti-electrostatic and lightning proof
- Protection Diodes and Resettable Fuses Onboard: Ensure stable voltage / currency output | prevent over voltage / current | shock resistance
- Contact Rating: ≤10A 30V DC or ≤10A 250V AC
- ABS Box: Easy to install ABS protection box | Rail Mount support | Safe to use
