Product Description:

Differential inputs are very useful, if analog sensors are used which are remotely non-isolated (e.g. the minus terminal is remotely earthed). Since the earthing potential is not exactly the same as
AGND1, it has to be measured bipolar in order to compensate measuring errors. Additionally, in case of singlepole configuration, AGND1 would be connected directly to the remote earth potential. This would cause inadmissable (and possibly dangerous) earthing loops. In all configurations using differential inputs two adjacent analog inputs belong together (e.g. EW 6,00 and EW 6,01). The measured value is calculated by subtraction. The value of the channel with the lower address is subtracted from the value of the channel with the higher address.

Product's Character:

The converted measured value is available on the odd address (e.g. EW 6,01). Important: The common mode input voltage range equals the measuring range of the single channel. I.e. that the signals,
related to AGND, at the two involved inputs must not exceed this measuring range. Input voltages which exceed the measuring range cause an overflow error message. If the measured value is below
the range, an underflow error message is generated.
