It is possible to use an S7 series PLC to convert a pulse train input (-24VDC to 0 "decreasing"on one set of contacts and 0 to +24VDC "increasing" on another) and convert this input into a 4-20 mA output? The application is a measurex gauging system moisture control output in time duration or pulse train. The Foxboro converter my customer once used is obsolete.
