The UniPak™ UP475 converts a DC current or voltage signal to a proportional, linear frequency signal providing 1500 Vac isolation between the frequency source, the dc output and power to the UP475. A typical application is totalizing applications, where the total number of pulses counted in a given time period represents the time integral of the DC input.
If, for example, the input represents a flow in gallons per hour, then the time integral of this flow signal (total count) will
represent total gallons. The input of the UP475 can supply voltage for a 2-wire current loop, up to 20 V dc. There are two output choices, an npn open collector or a reed relay. The open collector provides 30 V dc, up to 300 mA. The relay is rated for 30 V ac or dc and 100 mA. The open collector output can be used to drive electronic counters or other high speed inputs.
The relay can be used to drive electromechanical counters when connected to an external AC or DC power source. The
unsurpassed flexibility means that one model can meet many application requirements.

Signal Conditioning flexibility and use made simple from ioSelect, powered by Seneca (Z104)
