•
Low-impedance connection exists between '0 V DC' and GND analog output.
•
GND digital input and GND Ex are galvanically insulated from each other as well as
from '0 V DC'.
•
DC-powered units have 'DC +' and 'DC –' galvanically insulated from all other
clamps.
•
AC-powered units permit to tap the 24 V auxiliary voltage, which is also available
on '+24 Volt DC' (28) and '0 V DC' (39), from connections 'DC +'/'DC –' (clamps 4
and 5) too. AC units therefore have a low-impedance connection between 'DC –'
and GND analog output via the '0 V DC' connection. In contrast to the 24 V availa-
ble on clamps 28 and 39, the auxiliary voltage on 'DC +'/'DC –' (clamps 4 and 5) is
conducted through an internal extra common mode filter and 'DC +' can be ena-
bled/disabled by using the DC switch.
