3.9 Output 24V (X2 / 24V, GND)
The output 24V/GND can be used to power the optional external circuitry of the digital inputs , out-
puts or relays. The maximum current consumption must not exceed 500mA. A possible current
consumption via J2, J4, J6 or J7, J8, J9 must be factored in.

Note:
For the dimensioning of the power supply the power consumption for the external output
circuitry must be additional considered to the typical reader power consumption.
The internal 24V voltage on X2 is not protected by the fuse F1.
