Figure 2-24 Terminal assignment for the digital outputs
● Connection cable: The required connecting cables (ribbon cables) must be provided by
the user
.
● Supply voltage:
To supply the digital outputs, an external 24V DC power supply must be connected to
DOCOMx (X111, X222, X333: Pin 47, 48, 49, 50).
The reference ground of the external power supply source must be connected to X111,
X222, X333: Pin 1 (M)
For further data, see Subsection
"Power Supply" (Page 100).
CAUTION
It is the user's responsibility to ensure that the max. current consumption per DOCOMx
pin (X111, X222, X333: Pins 47, 48, 49, 50) does not exceed 1 A. The power supply
(+24 V DC) for the digital outputs must therefore be connected to all 4 pins (X111, X222,
X333: Pin 47, 48, 49, 50) for each DOCOMx.
