Zd-95-g-f Schematic (4K)

If the voltage sits below its rated spec (e.g., reads 4.1V instead of 5.0V), cross-reference the schematic to locate the filter electrolytic capacitors smoothing that rail.

Each relay coil trace includes a parallel freewheeling diode. These prevent inductive voltage spikes from flowing backward and destroying the driver transistors when a relay turns off. 5. User Interface (UI) and Communication Bus If the voltage sits below its rated spec (e
