Download Installation Guide



The IN-588A Prescaler is primarily designed and manufactured for use with flow transducers or other devices with frequency output signals.
It scales an incoming frequency to engineering units which it then sends out in the form of pulses through an optocoupler. These pulses can then be used to accurately drive totalisers or digital inputs to PLC's etc.

Typical applications could include scaling frequency from a flow transducer in a water pipe to pulses representing cubic metres or water used for display on a totaliser or scaling frequency from an encoder to pulses representing mm of linear movement for input to a PLC etc.
