Siemens SIRIUS 3RK3 - Expansion Module 8 DO

5.1.15 Expansion module 8DO
Properties
With the 8DO expansion module, the 3RK3 central unit can be expanded by further (non-safety-
related) outputs. It is suitable as an output module with non-safety-related outputs, e.g. for
messages.
• Parameterization is performed using the 3RK3 central unit with Safety ES software.
• Additional expansion modules can be connected to the expansion module 8DO.
Inputs and outputs
The 8DO expansion module has the following outputs:
• 8 standard semiconductor outputs (non-safety-related)
