Start-Up
7.7.5 Procedure for starting up expansion boards (EB1 and EB2)
Remove connector X480 from the EB1 board for safety reasons. A short circuit could
1
otherwise occur should the signal direction of the bidirectional binary inputs/outputs be
incorrectly parameterized (see also point 3).
This risk of short circuits does not exist on EB2 boards.
The analog inputs on the EB1 can be used either as current or voltage inputs, the mode
2
being selected by setting jumpers (X486, X487, X488) appropriately (see Function
Diagrams, Section 8). The same applies to EB2 (X498); on this board, the analog output can
also be configured as a current or voltage source (X499).
Parameterize the desired functions for the inputs and outputs (see Function Diagrams,
3
Section 8).
If you wish to operate a bidirectional binary input/output on an EB1 as an input, please note
that the output circuit must be deactivated in the corresponding parameter (e.g. U769.01=0).
A short circuit will otherwise occur if the signal levels of the external input and output signals
are opposed.
Switch off the device.
With the power supply disconnected, insert the adapter board with expansion board in a
4
location. Please remember to insert a board in location 2 before you use location 3.
EB1 boards only: Plug connector X480 back into board.

Expansion boards EB1 and EB2 expand the range of terminals on the basic converter. A total of 2
EB1 boards and 2 EB2 boards may be installed in one SIMOREG DC MASTER 6RA70. The EB1
and/or EB2 are plugged into adapter (carrier) boards (ADB). 2 boards may be mounted on each
ADB.
The EB1 provides the following expansion terminals:
3 binary inputs
4 bidirectional binary inputs/outputs
1 analog input for differential signal (current or voltage input)
2 analog inputs (single ended), can also be used as binary inputs
2 analog outputs
1 connector for external 24 V voltage supply to binary outputs
The EB2 provides the following expansion terminals:
2 binary inputs
1 connector for external 24 V voltage supply to binary outputs
1 relay output with changeover contacts
3 relay outputs with NO contacts
1 analog input for differential signal (current or voltage input)
1 analog output (current or voltage output)
For further details, see Section 8, function diagrams for expansion boards EB1 and EB2.
