PGND

Input signals (source operation): PGND

H = 15.. 30 V

L = -30.. + 5 V or no connected

Input signals (sink operation):

H = 15 .. 30 V or no connected

L = -30.. + 5 V

source operation

(for sink operation

L at +24 V)

Outputs OUT4 and OUT5 can be used as “normal”, short-circuit-proof transistor

outputs with addresses O 8104 and O 8105, and each loaded up to 0.5 A.

Where the OUT4/OUT5 outputs are used, the + connection (terminal 6) must have a

+24 V supply.
