How can I control 170 small 6V bulbs with MOSFET outputs (PWM dimming)

[hwang]

Hi everyone,
I am building a lighting control system for about 170 mini incandescent bulbs.
Load

• Bulbs: 6V, 0.2A each
  
• Total: ~170 bulbs
  

Hardware Plan
I plan to use multiple Kincony KC868-A32M (32-channel MOSFET output controllers) to get enough channels.
Wiring Idea
I want to use a common +6V bus and low-side MOSFET switching:

Code:

+6V bus → bulb → MOSFET output → GND

All controllers and the 6V supply will share a common ground.

Questions

1. Is this the correct wiring method for KC868-A32M outputs?
   
2. Can these MOSFET channels support PWM dimming for incandescent bulbs, or only ON/OFF?
   
3. What is the best way to control multiple KC868-A32M boards from a PC (LAN/MQTT/Modbus)?
   
4. Any important power or wiring concerns for a 170-bulb system?
   
   

Thanks for any advice!

1. mosfet output 12-24v, not suitable for 6V. if you want 6v load, suggest you chose relay controller.
2. mosfet output can't output PWM.
