Description
AXIS 207MW
Pin 4 With a maximum load of 100mA and
a maximum voltage of 24V DC, this
output has an open-collector NPN
transistor with the emitter con-
nected to the GND pin. If used with
an external relay, a diode must be
connected in parallel with the load,
for protection against voltage tran-
sients.
Pin 3 Connect to GND to activate, or leave
floating (or unconnected) to deacti-
vate.
Pin 1
Pin 2 Connected electrically in parallel
(5VDC with the power adapter, this pin
min 3.5W) provides an auxiliary connector for
mains power to the unit. It can also
be used to power auxiliary equip-
ment, max 50mA.
