Digital outputs
Data Value
Number of channels per device 16 high-side switches
Connections Connector X7 (terminals 1.0 ... 1.7)
Connector X8 (terminals 2.0 ... 2.7)
Division of channels in groups 2 groups with 8 channels (not electrically iso-
lated!)
Common voltage supply UP (supplies module DA501 and 502)
Common reference potential ZP:
-> for group 1 ZP (terminals 1.0 ... 1.7)
-> for group 2 ZP (terminals 2.0 ... 2.7)
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).
● 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
Indication of the output signals One yellow LED each per channel. The LED
corresponds functionally to the output signal.
Output current:
-> Rated value 500 mA at UP = 24 V
-> Residual current at 0 signal < 0.5 mA
Demagnetization with inductive load Internally via varistor
Switching frequency with inductive load max. 0.5 Hz
Switching frequency with lamp load max. 11 Hz at max. 5 W
Max. cable length 1000 m (shielded)
600 m (unshielded)
Short-circuit proof / overload proof Yes
Protection against reversed voltage of process
supply voltage
Yes
Resistance to feedback against 24 V signals Yes
Total load current (all DO channels, 1.0...1.7
max. 4A and 2.0…2.7)
max. 4 A
Total load current (all DC channels, 4.0..4.7
max. 8A and 8.0…8.7)
max. 8 A
Total load current (via UP) 16 DO channels
and 16 DC channels
max. 12 A (all UP terminals must be con-
nected)
