Digital inputs
Data Value
Number of channels per device 16
Connections Connector X2 (terminals X5.0…X5.7)
Connector X3 (terminals X6.0…X6.7)
Division of channels in groups 2 groups with 8 channels (not electrically iso-
lated!)
Voltage supply UP (supplies module DA501 and 502)
Common reference potential:
-> for group 1 (8 channels) ZP (terminals 5.0 ... 5.07)
-> for group 2 (8 channels) ZP (terminals 6.0 ... 6.07)
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
(reference M) is available.
● 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 resistorsFig. 18.
Configurability of the inputs Input delay configurable (0.1 ms, 1 ms, 8 ms
and 32 ms). Default: 0.1 ms.
Channels for high-speed counters
Ä
Chapter 1.4.1.3.4.6 “Digital inputs/outputs”
on page 48
Channels for high-speed counters are imple-
mented with the inputs/outputs (channels: 4.0
and 4.1).
Indication of the input signals One yellow LED each per channel. The LED
corresponds functionally to the input signal.
Input signal voltage: 24 V DC
-> 0 signal -3 V…+5 V
-> Undefined signal state +5 V ... + 15 V
-> 1 signal +15 V ... + 30 V
Input current per channel:
-> Input voltage = +24 V Typ. 5.0 mA
-> Input voltage = + 5 V > 1 mA
-> Input voltage = +13 V > 2 mA
-> Input voltage = +30 V < 8.0 mA
Max. cable length unshielded 600 m
Max. cable length shielded 1000 m
