Electrical / Functional Clues from Components

Transformers / Inductive Components

• Large yellow transformers marked:

  • 229C30

  • 24VA

• Indicates isolated low-power supply or signal isolation, not a high-power motor drive board.

Terminals

• Multiple green screw terminal blocks:

  • Likely for:

    • AC input

    • Control signals (gate/trigger lines)

    • Isolated outputs

• Labeled terminal blocks:

  • TB1

  • TB2

Opto-Isolation

• IC labeled ISO1

• Confirms optocoupler-based isolation, consistent with a gate isolator role.
