5.1.14 Expansion module 8DI
Properties
With the 8DI expansion module, the 3RK3 central unit can be expanded by further (non-safety-
related) inputs. The 8DI expansion module supplements a 3RK3 central unit.
• Parameterization is performed using the 3RK3 central unit with Safety ES software.
• It is suitable as an input module with non-safety-related sensor inputs, e.g. for:
– Displaying process statuses for operational switching.
– Detecting start buttons.
• Additional expansion modules can be connected to the expansion module 8DI.
Inputs and outputs
The 8DI expansion module has the following inputs:
• 8 sensor inputs (non-safety-related)
