N.C.
1) Always related to the 10V end voltage, even if the voltage range is limitted
2) AGND and DGND are connected internally. AGND SEL at Pin 14 is inpedendent. It serves as reference for the difference amplifiers of all analogue inputs.
DIx, DOx, +Vcc are referenced to DGND. VREF, VMON, CMON, PMON are referenced to AGND. VSEL, CSEL und PSEL are referenced to AGND SEL.
3) Digital input, depending on the preset with the jumpers:
a) Setting High Range (high threshold): U
= 0V; I = -1.5mA, U
in
b) Setting Low Range (low threshold): U
= 0V; I = -1.5mA, U
in
4) Positive currents are flowing out of the device, negative currents are flowing into it.
