Digital outputs
Assignment of the 25-pin Sub-D sockets
V 1.0
Each unit has eight (2 x 4) digital potential-free outputs. Like the digital inputs, these
are distributed to the two 25-pole Sub-D sockets (relay 1-4 and relay 5-8).
The digital outputs can be used, for example, to switch external devices to report
system errors. Corresponding events are created and set up in the G-Set
parameterization software.
The contacts can be soldered directly to the corresponding Sub-D plug. The assign-
ment of the 25-pin Sub-D connectors is shown in the following figure.
