D/D: 190605 S/N: 0074 20PYDT7G2

This is a Daikin Filter PCB (Printed Circuit Board), specifically model 20PYDT7G2. It is a heavy-duty component designed to handle high voltage—up to 460VAC and 20A, according to the silkscreen at the bottom.
In high-end HVAC systems like Daikin’s VRV or industrial units, this board acts as an EMI (Electromagnetic Interference) Filter. Its primary job is to clean up electrical “noise” coming from the power line and to prevent the unit’s internal electronics from sending noise back into the building’s grid.
