ATTENTION
:
Digital Input and output
cards must be supplied
with an extarnal 24V DC
source, otherwise the
cards can not be
detected by the recorder
and do not function.
Figure 7.5 Digital Input&Output Cards Connection Diagrams
Relay Outputs can be used with snubbers. To use with snubber, the terminals 2 and 3
should be short circuited with a suitable cable. Snubber consist of serially connected
a capacitor (10nF, 630 V) and a resistance (100
Ω
, 1/4 W) and can be used to
suppress the contact noise. While the contact is used for switching AC signals and
snubber is connected, impedance of the snubber should be taken into consideration.
