Solid, Slim Relay for Control Systems - My Take - ppappa

I recently needed to upgrade the control system in my setup, specifically looking for a reliable way to handle some valve shut-offs, which led me to purchase the LANBOO LBJ21A General Purpose Relay, 2NO2NC 8 Pin & 4NO4NC 14 Pin, 5A/12A 12V/24V/220V AC/DC, Slim 21mm with Socket Base. Finding a relay that offered the flexibility of both 8-pin and 14-pin configurations, along with multiple voltage options, was key for this project, so this looked like a strong candidate on paper.

I immediately noticed how compact this device is; while one reviewer mentioned it's 'not a small relay,' I found the slim 21mm profile quite manageable for panel space, especially considering the switching capacity it offers. Installation was straightforward enough, and I appreciate that the order connections were well-indicated, making the wiring process relatively painless, even if the arrangement was slightly unusual for me initially. I installed several units to manage different circuits, and initially, they performed exactly as specified, living up to the 'Quality product and meets specifications' comment I saw from other buyers.

It's nice when something arrives fast and works right out of the gate.

However, I did experience an issue after a short operational period—a couple of the coils failed surprisingly quickly, which is definitely frustrating when you're relying on them for continuous operation. This is something potential buyers should keep in mind, though other users seem satisfied with their results. Despite that hiccup, the core functionality, when operational, is robust, handling the required current well.

For general purpose switching where immediate, high-cycle reliability isn't the absolute top priority, this product certainly delivers on features like its dual contact configurations.

Overall, if you are looking for a versatile relay offering multiple pin counts and voltage flexibility in a reasonably slim package, this device is worth considering. If you are ordering a batch, perhaps test a few before installing everything, just in case you run into the coil durability issue some of us have noted. If you need a good general-purpose switching solution, the LANBOO LBJ21A is certainly a good item to look at.
