Waveshare 33917 Industrial 8-Ch Ethernet Digital Input / Output Module Modbus RTU / TCP Protocol, Supports PoE Power Supply

1. Onboard voltage regulation chip, supporting a wide voltage range from 7V to 36V, and supporting PoE Ethernet power supply
2. Supports control via MQTT protocol, providing Alibaba Cloud MQTT application routines
3. Onboard integrated power isolation, capable of providing stable isolated voltage, and the isolated end does not require additional power supply
4. Input features bidirectional optocoupler isolation, supporting passive and active switch input, built-in anti-jitter algorithm, relays support switch input linkage mode or inversion mode control
5. Output uses Darlington, with optocoupler isolation, stronger driving capability, with a driving current of up to 500mA, and built-in reverse current diode protection
6. Output has flash-on and flash-off functions, can be set with parameters in the instruction, automatically turns off after a certain period of time after the output is turned on
7. Rail-mounted enclosure design, convenient installation, safer to use
8. External indicator light, convenient for checking input/output status, MCU status and signal transmission/reception status
9. Size: about 14.5 x 9 x 4 cm
