Vulcan S100 Electronic Anti-Scale Water Treatment System Circuit Board

This is an internal electronic control board for a Vulcan S100, which is a physical water treatment system designed to prevent scale buildup in pipes. The device features a black 'Made in Germany' printed circuit board (PCB) encased in a transparent protective acrylic or glass housing. The PCB is densely populated with through-hole components, including multiple light-blue resistors, black integrated circuit (IC) chips, capacitors, and a series of green and red LED indicators. Notably, the board displays a diagnostic menu for various pipe sizes ranging from 2 1/2 inches to 6 inches for metal and 75mm to 150mm for plastic, suggesting a versatile industrial or commercial application. The bottom left is clearly marked with 'Vulcan S100 Made in Germany' in a white sans-serif font. On the right side, there are several metallic 'Impulse' connection ports and a green 'Power' indicator light. The craftsmanship is reflective of high-quality German engineering common in the early 21st century, showing clean solder points and a structured layout. The condition appears to be excellent with no visible signs of thermal damage, component leakage, or oxidation on the silver-colored traces. The housing is clear and free of significant scratches, suggesting it was well-maintained or part of a display model.
