The '''IBM 1711 Data Converter''' was part of the [[IBM 1710]] [[process control]] computer. The 1711 contained an [[analog-to-digital converter]] that accepted signals from the [[IBM 1712]] Multiplexer and Terminal Unit that were between -50 [[milli]][[volt]]s and +50 millivolts and converted them into signed, four decimal digit numbers that were stored in the 1710s [[core memory]].

The 1711 featured a [[real-time clock]] that could place the current hour and minute into storage, again as a 4 digit number. On the 1711's control panel, there was a bank of seven decimal digit manual entry switches that could be read by the computer. The 1711 also contained address circuitry for the IBM 1712 Multiplexer.

Optional 1711 features included contact sense, contact operate, [[digital-to-analog converter|analog output]], [[interrupt]], and process branch indicators.<ref>{{Cite web |title=1711 Operator's Panel |series=IBM Systems Reference Library |url=https://123dok.net/article/operator-s-panel-systems-reference-library.y4wr9e15 |url-status=live |archive-url=https://web.archive.org/web/20220821155951/https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8035331/ |archive-date=2022-08-21 |access-date=2022-08-21 |website=123dok.net |language=en-US}}</ref>

While all this and more would fit comfortably on a single [[integrated circuit|IC]] today, the IBM 1711 occupied a three section rack cabinet.
