Digital outputs
The board
PA 1500
supplies 16 optically isolated outputs. The outputs
comply with the 24 V industry standard (IEC1131-2)
The positive logic is used
-
logic "1": sets the output by software (switch on ON),
-
logic "0": resets the output (switch on OFF).
The outputs switch the
+24V
ext.
outside to the load. One end of the load is
connected with the ground of 0V EXT (outputs).
All outputs have a common ground: 0V ext. (outputs) pin 29 of the 37-pin
SUB-D male connector.
WARNING!
Do you use all outputs with the same voltage supply?
The voltage supply must deliver at least the power required for your
application.
The maximum supply voltage is 36 V. Each output can switch 500 mA
current. But the current is limited for all the outputs on approx. 3 A by a
self-resetting fuse.
