P24 X431.1 External supply for digi-
tal outputs
(+24 V)
S Voltage tolerance (including ripple): 10 V to 30 V
Max. aggregate current: 2.4 A
Note:
S The external supply is required for the four digital outputs
(O0 A O1 A and O0 B O1 B)

S When dimensioning the external power supply, the total
current of all of the digital outputs must be taken into ac-
count.
9 X431.3 Enable voltage
(+24 V)
S Reference: Terminal 19
Maximum current(for the total group): Max. 500 mA
Note:
The enable voltage (terminal 9) can be used to supply the
enable signals (e.g. pulse enable) as 24 V auxiliary voltage.
