5.1.10 Expansion module 8DO
Properties
The expansion module 8DO supplements the central unit. It is suitable as an output module
with non-safety-related outputs, e.g. for messages.
● Additional expansion modules can be connected to the expansion module 8DO.
● Parameterization is carried out via the central unit with MSS ES.
Inputs and outputs
The expansion module 8DO has the following inputs and outputs:
● 8 semiconductor outputs (non safety related)
