interfaces
6.2.7.1 Voltage supply for I/O interfaces
IMPORTANT
24V external:
The integrated I/O module of the AST40 must be fed
with 24V DC to use the inputs / outputs as well as the
emergency stop circuit.
This is done by feeding 24V DC via the pins 2/3 and
21/22 at plug connector GX2 (interface SPS ) or via
pins 3 and 4 at plug connector GX9 (emergency
stop).
24V internal:
Internal 24V DC of the AST40.
This output may be loaded with max. 150 mA.
