Digital inputs/outputs
Data Value
Number of channels per device 16 inputs/outputs
Connections Connector X1 (terminals 4.0 ... 4.7)
Connector X9 (terminals 8.0 ... 8.7)
Division of channels in groups 2 groups of 8 channels each
Group 1: terminals 4.0 ... 4.7
Group 2: terminals 8.0 ... 8.7
Common reference potential ZP All digital I/O channels of the DA501 and
DA502 module
Common voltage supply UP (supplies DA501 and DA502 module)
Electrical isolation Electrical isolation from group to group is no
longer available.
Electrical isolation from DA501 and DA502
(reference ZP) to the rest of the device (refer-
ence M).
On DA501 and DA502, all digital channels
have the same potential ZP.
AGND1 and AGND2 of the analog channels
are internally connected to ZP via PTC resis-
tors.

Configurability of the inputs:
-> Input delay Typically 0.1 ms, configurable from 0.1 ms to
32 ms
Indication of the input/output signals 1 yellow LED per channel. The LED is ON in
"High" signal state (1 signal)
