The Modbus RTU Relay is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment and/or applications with high communication requirement.
Features
- Configurable device address (1~255), multi devices can be cascaded on RS485 bus
- Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
- Onboard unibody ADI magnetic isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic
- Onboard Optocoupler isolation, prevent interference from external high-voltage circuit connected to the relay
- Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
- High quality relay, contact rating: ≤10A 250VAC/30VDC
- Rail-mounted ABS plastic enclosure, easy to install, safe to use
- 3 LEDs for indicating the MCU status and signal transceiving status

Ladies, don't be afraid. Buy 'em. Trust me
Size: 9.5, Color: A Black
My elderly mother adores these. She had to have breathable awesome shoes for post-surgery and these fit the bill (and her feet!)
So i got some for me. Whoa. Comfort! And I love the slip-on ease, b/c sometimes I just need to go, go, and go some more. Love them in black, haven't had long enough for durability, but helpful for my mom in her physical therapy and they're holding up to the worst she can do to them.

Good overall shoe, great for basic needs
Size: 12, Color: A Black
These are nice shoes. I put $40 arch support insoles in mine, so I like them even more, but they were fairly comfortable even without. They fit well, though slightly large, and seem to hold up well. No real complaints, though made a bit cheaply.

Great walking shoes
Size: 11, Color: All Black
A very comfortable walking shoe that’s well made and looks like it’s going to hold up well for everyday wear. Lightweight indeed and probably doesn’t require much cleaning. Easy to get on and off without much stress though.
