Connector X7 (terminals 1.0 ... 1.7)
Connector X8 (terminals 2.0 ... 2.7)
2 groups with 8 channels (not electrically iso-
lated!)
UP (supplies module DA501 and 502)
ZP (terminals 1.0 ... 1.7)
ZP (terminals 2.0 ... 2.7)
● Electrical isolation from group to group is
no longer available.
● Electrical isolation from DA501 and DA502
(reference ZP) to the rest of the device
(reference M).
● On DA501 and DA502, all channels have
the same potential ZP. Voltage supply
UP/ZP.
● AGND1 and AGND2 of the analog chan-
nels are internally connected to ZP via
PTC resistors. Fig. 18
One yellow LED each per channel. The LED
corresponds functionally to the output signal.
