Application Notes

EAP-031042

I need to indicate flow pulse signals (10,000 pulses/hour) at two independent integrating counters. Maximum input to each counter is 500 pulses/hour.

You have to first scale the flow signal of 10,000 pulses/hour down to 500 pulses/hour (1), and then distribute the pulse output to two counters (2). See the system configuration below.

(1) Frequency Scaler (model PRU, KPRU, etc) In order to convert 10,000 pulses into 500, set the scaling factor to 0.5 x 10^-1. You can set the factor with front-mounted rotary DIP switches. Input: mechanical contact, open collector or voltage pulse Output: open collector, relay contact or voltage pulse Scale: 0.9999 x 10⁰ - 0.0001 x 10^-6 (PRU/KPRU) (2) Pulse Isolator (model KMT) It provides two isolated contact output signals. Input: mechanical contact, open collector Output: relay contact, open collector
