the status
High/

Max load =
100mA
Max voltage =
24V DC
(to the transis-
tor)
Uses an open-
collector NPN
transistor with
the emitter con-
nected to the
GND pin. If used
with an exter-
nal relay, a
diode must be
connected in
parallel with the
load, for protec-
tion against
voltage tran-
sients.

sources looses a
connection with
a camera, AXIS
