Description

The HCTL-2xx1(7)-A00/PLC is CMOS ICs that performs the quadrature decoder, counter, and bus interface function. The HCTL-2xx1(7)-A00/PLC is designed to improve system performance in digital closed loop motion control systems and digital data input systems. It does this by shifting time intensive quadrature decoder functions to a cost effective hardware solution.
