The QD60P8-G is an 8-channel pulse input module with channel-to-channel isolation. It supports input frequencies of 30k, 10k, 1k, 100, 50, 10, 1, and 0.1 pps. Counter input signals accept DC 5/12–24V. It is used for measuring speed, rotational speed, instantaneous flow, quantity, length, and cumulative flow. Pulse input values are updated every 10 ms, and cumulative counts as well as moving-averaged pulse values (sampled pulse counts) can be updated according to the set counting cycle.
