In AC consumers with low power the current flowing through the capacitor of the spark quench-
ing element when the contact is open may interfere (e.g. the hold current of some switching ele-
ments is not dropped below). In this case the capacitors (1 μF) must be removed and replaced
with low capacitance capacitors.
The 68 V suppressor diodes parallel to the capacitors act additionally to reduce the induced
voltage.

The relays used on the digital output module are designed for a
maximum rating up to UC 35 V. The same applies for the air and creep
lines on the circuit board. Higher voltages may therefore only be
switched through appropriately approved series connected circuit
elements under observance of the technical data and the pertinent
safety regulations.
6DR2801-8E Module 2 BE and 4 BA
D Digital signal module with 2 digital inputs and 4 digital outputs
The module serves to extend the digital inputs and digital outputs already existing in the stan-
dard controller.
The inputs are designed for the 24 V logic and are non--floating. The functions are assigned to
the inputs and outputs by configuration of the controller.
The digital outputs are short--circuit--proof and can drive commercially available relays or the
interface relays 6DR2804--8A/8B directly.
6DR2801-8C 5 BE
D Digital input module with 5 digital inputs
The module serves to extend the digital inputs already existing in the standard controller .
The inputs are designed for the 24 V logic and are non--floating. The function is assigned to the
input by configuration of the controller.
6DR2802-8A Analog output module with y-hold function
For auxiliary control device function when servicing and for extending the analog outputs AA1 to
AA3 existing in the standard controller .
Can be used in slot 5/6, oP5/oP6 = 1 AA must be set in the hdEF structure mode
Start value of the outputs can be set with AA4/AA7 = 0/4 mA in hdEF
