Leo,
Your first picture is our “S” or “V” version of the 5D Module………… the “S” is for screw terminals on each end, and +/- 5 Vdc analog output. The “V” version is the same but with +/- 10 Vdc output. I cannot tell which version due to the side label not in the picture.
The second picture is our standard 5D70 which has the 10 pin connector on the top for the transducer and the bottom is a DB25 connection. The unit functions the same but the connection, pin out is different…… also the analog output is +/- 5 Vdc.
If the user needs to connect the second unit, they can use it with a standard female DB25 connector and wire up the signals as noted on the unit or in the manual on page 9.
If they need the 10 Pin connections (and maybe the 10 V output) then the module needs to come back for retrofit.
This can be done at our Miamisburg office, no cost except for shipping,
Hope that helps.
