Old Analogue PDL5 Board Morphs to Digital ZDL5 Switcher!
- This is the first ZDL5.FTe Switcher ever built, it "reads" the Kellers it is attached to in digital mode, it beats an analogue PDL5 switcher in all categories, it is a ZDL5.FTe, and that means it uses two Keller singles to measure flow, operation identical to the CDi3.Fte but "talks" to the computer and to its Kellers at 9600 baud. There will be a ZDL5.RMe soon, this one will use a differential Keller and a single Keller to measure flow, much like we have been doing with the P5 switchers.
- Because it reads all the pressures digitally, it does everything in 2.9 seconds as opposed to 6 seconds for its analogue cousin. The pressure transmitters only need to be powered up for less than a second as opposed to almost 6 seconds of its analogue cousin. This results in the ZDL using just over a third of the power the analogue P5 uses.
- This ZDL eliminates calibration, the user only needs to select a pressure range from a menu.
- Application software for both the ZDL5.FTe and the ZDL5.RMe is CDiComm.
- Here is the ZDL5 Switcher development page, installed the first one June 9th, 2017.
