Waveshare 24964 Industrial 8-ch Ethernet Relay Module, PoE Port Communication(Modbus POE ETH Relay)

Features: 1. With flash-on and flash-off functions, you can add parameters in the command to operate the relay to automatically close after a period of time 2. Support DC 7-36V wide voltage power supply, support PoE Ethernet power supply 3. Support control of relays through MQTT protocol, and provide Alibaba Cloud MQTT application routines 4. Onboard optocoupler isolation to avoid interference from relay high-voltage circuits 5. Adopt dedicated relay driver chip, built-in freewheeling diode protection, stronger and more stable driving ability 6. Switch input with bidirectional optocoupler isolation, support passive and active switch input, built-in de-jitter algorithm, relay supports switch input linkage mode or flip mode control 7. Onboard anti-reverse connection circuit to avoid reverse connection of positive and negative poles and burn out the circuit (only 8-way B version) 8. Adopt high-quality relays, allow access to loads: less than or equal to 10A 250V AC or less than or equal to 10A 30V DC 9. Guide rail type ABS protective shell, easy to install and use, safer with shell 10. Four external LED indicators and a network port indicator light make it easy to check the MCU status and signal receiving and sending status Product parameters: 1. Communication interface (DO): Ethernet (supports PoE) 2. Communication protocol: TCP/UDP/MQTT 3. Modbus protocol: Modbus RTU protocol or Modbus TCP protocol 4. Device address: cannot be set, identify the device by IP address 5. Output control: 8 relays 6. Relay type: one normally open, one long closed 7. Relay access load: less than or equal to 10A 250V AC or less than or equal to 10A 30V DC 8. Input control (DI): 8 inputs 9. Power supply: PoE network port, DC 5.5 x 2.1 power interface or terminal block 10. Power supply range: 7-36V wide voltage 11. Installation method: standard DIN 35mm rail installation or screw hole wall installation 12. Dimensions: 145 x 90 x 40mm
