Compared to the ZSE20, the ZSE20AF adds a 2nd switch output, as well as an analog output, either voltage or current.  ZSE20A is vacuum rated, while the ZSE20AF is rated for vacuum and a low positive pressure range.  Each model in the ZSE20 family offers a 2-screen, 3-color display.  The main screen shows the current measured numeric value in orange.
