How to install Brainboxes - Ethernet to 4 Relays and 8 Digital Inputs + RS485 Gateway

To install this gateway, begin by ensuring your power supply and network environment meet the device’s requirements. Verify a clean, shielded installation area to minimize electrical noise, and confirm that the 24V DC power source is connected with correct polarity and adequate current capacity for your load. Connect the Ethernet cable to a steady network switch or router, and assign an IP address according to your network policy—static addressing is often preferred for industrial installations to simplify device discovery and monitoring.

Next, wire the 8 digital inputs to your sensors, switches, or safety devices. Use proper cabling practices for 24V logic, and maintain awareness that these inputs are non-isolated; ensure a common reference is shared with the device to avoid ground loops or voltage transients. Wire the 4 relay outputs to the controlled devices, keeping load currents within the relay ratings and using appropriate suppression for inductive loads when necessary. If you plan to utilize the RS485 gateway, connect the RS485 pair with correct polarity and configure the bus settings (baud rate, parity, stop bits) to match your existing PLC or controller network. Once the physical wiring is complete, power up the gateway and begin the configuration process using the provided software interface or web-based management portal.

Configuration and commissioning are straightforward: access the Brainboxes interface through a web browser or the manufacturer’s software tools, define input debouncing and filtering parameters, assign logical names to inputs and outputs, and set up simple automation rules or event-driven responses. For reliability, enable appropriate watchdog or heartbeat settings if supported, and implement a basic fault reporting mechanism so operators are alerted to any channel failures or communication issues. Finally, conduct a thorough functional test—activate each relay, simulate input signals, and verify RS485 communication with a representative endpoint to confirm end-to-end operation before placing the device into production use.

Excellent Cabinet for someone good at mounting a cabinet
Color: White, Style: Wall Cabinet
The cabinet arrived very well packaged with an instruction booklet, hardware, and an Allen wrench. The booklet says you will just need a Phillips screwdriver, but you will also need a drill with an appropriate bit (more on the bit later) to mount the cabinet on the wall. Assembling the cabinet was simplified by how well the cabinet pieces and hardware were labeled and referenced in the instruction booklet. The holes in all the cabinet parts lined up nicely. The doors swing on spring loaded pivots. They are not adjustable, but work well and are probably much less expensive than European style hinges. I was concerned that the doors would not line up, but they look fine. The Magnetic Latch also works well, but the little piece of wood that it mounts on fell off during assembly so I glued it back in place. This was the only problem I had assembling the cabinet. I let the glue dry overnight and mounted the cabinet the next day. The wood support plate they ship with the cabinet is a great way to hang a cabinet, however I did have some problems using the supplied anchors. I recommend having some other anchors and screws available in case you have similar issues. Skip this paragraph if you do not care about the details: I mounted the cabinet on drywall. The instructions said to drill 11/32” holes for the supplied plastic wall anchors. I did not have an 11/32” bit so I used a 5/16” bit. Even though my holes were 1/32” smaller than specified, the anchors slid into the drywall very easily without having to tap them. I recommend using a 5/16” bit or even a 9/32” bit instead of the 11/32” they specify. Next I mounted the support plate with the supplied screws, but I could not get the screws tight enough to hold the plate securely in place. It felt like the screws were too small in diameter so I used some slightly larger screws. That worked fine for one of the screws holding the plate and the two lower screws, but the second screw through the plate would not bite and hold the plate firmly. Fortunately I had one HILTI 3/16” hollow wall metal anchor left over from a previous project and was able to get the plate very solidly attached to the wall. My wife is very pleased with the cabinet. I did have some trouble with the latch and the install so I was tempted to knock off a star, but I think this is a 5-Star item considering the low cost and how well the the cabinet parts aligned with each other.

Love and amazing for the price!
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
Perfect! I'm a renter and didn't want to spend an arm and a leg on something that might not work in the next place so this looked like it would be a good fit. I really wasn't expecting much for the price point but I was VERY pleasantly surprised. It's a great piece. I love assembling things (I'm an Ikea pro) but this had literally the easiest and most explicit instructions I have ever seen. Every piece is clearly labeled. The hardware comes in a bubble pack, again clearly labeled. Rhe instructions are very clear. Another thing I appreciated was the mounting mechanism which is a French cleat. It is much easier to level and screw in a cleat than to recruit help and try to hold a cabinet in place and try screwing it in. I'm a fat middle age woman and I had no problem mounting it by myself. Notice there are no screws visible on the outside. That was a huge selling point for me. Only con is that for the quality of everything else, the shelves are on the thin side, placing anything substantial would definitely make them bow. Background is a scrap of peel-and-stick.

Good cabinet choice
Color: White, Style: Wall Cabinet
I needed a wall cabinet for a recessed area above the toilet. This one fits the area perfectly and provides a good amount of storage in an otherwise wasted space. It looks good as it coordinates well with my white shaker style cabinets elsewhere in the room. It was easy to assemble, doors lined up perfectly, and mounting was a breeze with the included screws and hardware. It doesn't get hard use in this location, but seems sturdy after almost a year.

Easy to assemble and install
Color: White, Style: Wall Cabinet, Color: White, Style: Wall Cabinet
This cabinet meets our need for more bathrooms storage without interfering with the space in our smallish bathroom. The package arrived well packed in cardboard with foam inserts to protect the parts from damage in transit. I was able to easily follow the included directions with minimal fuss. In several cases, extra hardware piece were included, which I really appreciated. The quality of the construction was excellent. The only this that concerned me was the weight bearing capability of the included shelves. I added a few liquid or lotion filled bottles and noticed the shelves sagging, so I may have to cut my own shelves to better support. The cabinet looks great and is exactly as pictured in the listing after I assembled it. The ability to customize the shelves is also helpful. I looked at several cabinets for this purpose, some more expensive, some less, and I am happy with the money spent for this cabinet.
