As a completely self‑contained counter/display module, SCUB1/SCUB2 (5 V) and SCUB1LV (3.3 V) can be treated like an I.C. The module contains a custom counter/driver chip that performs all the counting functions together with a 6‑digit LCD readout. The latchable display with the separate reset function permits the module to be used as frequency or rate meter, timer, phase‑angle or pulse width indicator and for other complex readout requirements in addition to simple high speed counting.
