INFORMATION
When using an analog input of the E-727, both the corresponding +Analog In and –Analog In line must be
wired.
 Connect a differential signal (+analog, -analog, GND) as follows:
Customer Device
E-727.xxxA, .xxxAx
+Analog Out
+Analog In
-Analog Out
-Analog In
GND
GND
 Connect a single-ended signal as follows (recommended):
Customer Device
E-727.xxxA, .xxxAx
+Analog Out
+Analog In
GND
-Analog In*
GND
GND
* If it is not possible to connect –Analog In to GND on the customer side, -Analog In should be
connected to GND on the E-727 side.
 In either case, use a shielded cable.
INFORMATION
To achieve the highest possible resolution and eliminate potential interference that affects the cable used:
 Filter the analog output signal of the E-727 in a suitable way, e.g., before you convert it to a digital
format. Recommended: low-pass filter with max. 100 kHz cut-off frequency (characteristics: single
pole, 6 dB/octave)
