Kincony A-128 – Digital Output LEDs glowing when OFF + module freezes when switching

[krzemodam2]

Hello,
I am experiencing two possibly related issues with my Kincony A-128 controller.

---

Issue 1 – Digital Output LEDs glowing when OFF
Some Digital Output LEDs are glowing dimly even when the outputs are OFF in the control panel.
When I turn an output ON, the LED becomes much brighter (normal behavior).
Details:

• One section has 8 LEDs dimly ON
  
• Another section has 4 out of 8 LEDs dimly ON
  
• The remaining 14 sections work correctly
  
• The issue always affects the same sections
  
• LEDs are visible directly on the board
  
• I may have accidentally caused a short circuit on these outputs during wiring

Issue 2 – Module freezes when switching all outputs ON
When I use Home Assistant and press a button that turns all relays ON at once, the following happens:

• The module freezes
  
• All channels turn OFF
  
• Home Assistant shows the device as offline
  
• The module does not reconnect automatically
  
• I have to disconnect power completely and power it on again for Home Assistant to discover it again
  

Important observations:

• If I turn the outputs on slowly / step by step, the problem does not occur
  
• The problem only appears when switching many outputs ON simultaneously

Load and power details

• Most outputs are connected to 6A relays
  
• Some outputs are connected to WAGO 16A relays (higher current consumption)
  
• All relays and the A-128 module are powered from the same 24V power supply
  
• Control voltage and relay supply voltage are both 24V

Questions

1. Could the dimly glowing LEDs indicate damaged output channels?
   
2. Could the freeze/offline behavior be caused by power supply overload or voltage drop when switching all outputs at once?
   
3. Is this a known behavior of the A-128 when driving many relays simultaneously?
   
4. Has anyone experienced similar issues with A-128 and Home Assistant?
   

I am attaching photos of the board showing the glowing LEDs.
I can also provide:

• Firmware version
  
• Power supply specifications
  
• Voltage measurements during switching
  

Thank you for any help or suggestions.
Best regards
