This passive industrial logic module is engineered with three independent OR gate circuits designed to consolidate control signals, interlocks, and permissive loops in high-reliability systems. Because the signal paths are non-amplified, the module functions with zero current draw from the system power supply, making it an exceptionally stable and fail-safe component for discrete industrial logic control panels.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;

Ensure downstream receivers can accurately detect the logic-high threshold despite cumulative series voltage drops.
