Digital I/O module -- One of the
most important sections on an AS-Interface module
data sheet covers electrical specifications of inputs and outputs.
In this episode, Tim and Helge discuss the VBA-4E4A-G11-ZAJ/EA2L-F
AS-Interface module, as an example.
- --AUX -- Auxiliary power is
typically used to power outputs.
- --Rates operating voltage --
This is the voltage requirement available to the module at the
location where it is connected to the cable.
- --Operating current -- This is
the current needed to run the module. Sensors and load
current are extra.
- --Max. current -- This is the
total current consumed by the module. This includes the
operating current, the current it can supply to the sensors, and
the load current.
- --Current loading capacity --
This the current the module can provide to run the sensors and the
resulting load current.
- --Input current – This is the
internally limited load current.
