Waveshare 30544 Industrial Dual Ethernet Ports 8-ch Relay Module: Dual Ethernet port design
Available Options
Waveshare's Industrial Dual Ethernet Ports 8-ch Relay Module isn't just another piece of hardware—it's the muscle behind your industrial operations, built tough for the real world. Imagine this: a dual Ethernet setup that not only talks the talk with seamless communication but also walks the walk with PoE power supply cascade. And here's a neat trick—flash-on and flash-off functions let you command the relay to shut down automatically after it's done its job, like a reliable worker clocking out after a hard day's work.
Now, let's dive into what makes this module stand out from the crowd (because, let's face it, nobody likes a boring tech spec list):
- It's not picky about power, happily gulping down anything from DC7V to 36V, and yes, it plays nice with PoE Ethernet power too.
- Control freaks, rejoice! You can boss around the relays using the MQTT protocol, with Alibaba Cloud MQTT application routines ready to roll.
- Ever been annoyed by interference? The onboard optocoupler isolation says 'not today' to relay high-voltage circuit meddling.
- A special relay driver chip, complete with a built-in freewheeling diode, is like having a bodyguard for your circuits.
- Switch input comes with bidirectional optocoupler isolation, supporting both passive and active switch input—because options are good.
- Messed up the wiring? The onboard anti-reverse connection circuit has your back, preventing those 'oops' moments with reverse polarity.
- High-quality relays mean you can hook up loads ≤10A250VAC or ≤10A30VDC without breaking a sweat.
- Slap on the guide rail ABS protective shell for a setup that's as easy as pie and safer than a padded room.
- And because we know you like to keep an eye on things, there are external 4 LED indicators and network port indicators for a quick health check.
