Internal power supply (P24OUT
INT
)
The internal power supply for the digital inputs (X111, X222, X333: pin 2) is taken from the
general power supply of module X1, pin 2 (P24).
Caution
Make sure that a max. current of I
out
= 0.25 A at X111, X222, X333 on pin 2 is not exceeded.
Exceeding of the maximum current may destroy the module.
External power supply
If an external power supply is used for the digital inputs, their reference ground must be con-
nected to X111, X222, X333: pin 1 (M).
In this case, X111, X222, X333: Pin 1 (P24OUT
INT
) remains open.
