Raspberry Pi Zero WH RS485/CAN Industrial 6-ch Relay Module with Isolated Protections(US Plug)
Features：RS485 half-duplex communication: using SP3485, UART control, auto RX/TX switchCAN half-duplex communication: using MCP2515 + SN65HVD230 solution, SPI controlOnboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminalOnboard photocoupler isolation, prevent interference from external high-voltage circuit connected to the relayOnboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostaticOnboard resettable fuses and protection diodes, ensuring current/voltage stable output, preventing over current/voltage, better shock-resistance performanceHigh quality relay, contact rating: ≤10A 250V AC or ≤10A 30V DCABS protection enclosure with rail-mount support, easy to install, safe to useComes with development resources and manual (wiringPi and python examples) Specifications：OPERATING VOLTAGE: 7V~36V (industrial input voltage compatible)COMMUNICATION PROTOCOL: RS485, CANRELAY CHANNEL: 6CHCONTACT FORM: 1NO 1NC Enclosure DesignABS Protection Enclosure With Rail-Mount Support, Easy To Install, Safe To Use What's On Board： MCP2515CAN controller SI8642ED-B-ISdigital isolator SN65HVD230CAN transceiver SP3485ENRS485 transceiver LM2596 voltage regulatorproviding stable 5V voltage Photocoupler isolationprevent interference from external high-voltage circuit connected to the relay 6-channel quality relayscontact rating per channel: ≤10A 250V AC or ≤10A 30V DC Power supply isolationprovides stable isolated voltage, needs no extra power supply for the isolated terminal Resettable fuses TVS diodes Relay and power indicators 40PIN GPIO headersuitable for Raspberry Pi Zero with pre-soldered pinheader Relay screw terminalsfor connecting with user devices Power supply screw terminals RS485 bus interface CAN bus interface RS485 120Ω terminal resistor switch CAN 120Ω terminal resistor switch Relay control pins External power supply jack Thickened tracksallows large current devices Pinout Definition Outline Dimensions： Package Included:1x ABS protective case 1x RPI ZERO Relay 1x Screwdriver1x Screw1x 12V 1A power supply
