Harmony, Modular multifunction control relay – RM22TR33
This Harmony RM22-TR gadget is like a power watchdog for big machines. It checks if the electricity in 3-part systems is too high, too low, or unbalanced. It’s super slim (like a skinny phone) and snaps onto rails easily. Used in factories, elevators, or water pumps, it has simple dials to adjust, a button to test problems, and tells you what’s wrong so you can fix it fast. Perfect for old systems needing a safety upgrade without fancy computers!
