This Series B module effectively offloads complex counting tasks from the controller's main processor, processing input signals at frequencies up to 1 MHz. This hardware-level processing is critical for applications where the PLC scan time is too slow to accurately capture high-speed events.\u003c\/p\u003e\n\u003cp\u003eFeaturing two independent 32-bit counter channels, the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e1756-HSC\/B\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003esupports various input modes, including quadrature encoders, pulse\/direction, and up\/down counting.
