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:
Connect a single-ended signal as follows (recommended):
* 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)
