B8 – Defective screw terminals and compatible 8-pin pluggable terminal

[chrisbati]

Hello,

I recently purchased a KinCony B8 Smart Controller and I'm experiencing a problem with the green screw terminal blocks used for the relay outputs (KA1–KA8 / KB1–KB8).
When tightening a wire, the screw initially starts to grip, but the wire is not yet securely held. If I tighten it slightly more, the screw suddenly loses its grip and spins freely without tightening the wire anymore.

I have already experienced this problem on several terminals out of the five I have tested.

Since these terminals will be used to control 230 V AC lighting circuits, I don't want to risk loose connections or overheating.

I would appreciate your advice on the following questions:

1. Is this a known issue with the KinCony B8 terminal blocks? Is there a recommended solution?
   
2. Are the KA/KB terminal blocks soldered directly to the PCB, or can they be removed and replaced without soldering?
   
3. Is it possible to replace them with 8-pin pluggable screw terminal blocks, so that the wiring can be disconnected more easily?
   
4. If so, could you provide the exact compatible part number, including the pitch (5.0 mm, 5.08 mm or another size), and where I can purchase these connectors?
   
5. If replacement requires soldering, is there another solution, such as obtaining a replacement board or having the unit replaced under warranty?
   

Please note that I have no electronics or soldering experience. I am comfortable with electrical wiring, but I cannot modify or solder components on a PCB myself.
Ideally, I am looking for a simple, safe and reliable solution that does not require any electronics work.

Thank you in advance for your help!
