Pin
1
Electrically connected in
parallel with the
connector for the power
supply, this pin provides
an auxiliary connector
for main power to the
unit. This pin can also
be used to power
auxiliary equipment with
a maximum current of
100mA.
Voltage:
12V DC,
Max: 1.2W
DI1
(Digital
Input)
Pin
2
Connect to GND to
activate, or leave
floating (or
unconnected) to
deactivate.
Must not be
exposed to
voltages
greater
than 30V DC
DO
(Digital
Output)
Pin
3
Uses an open-collector
NPN transistor with the
emitter connected to
the GND pin. If used
with an external relay, a
diode must be
connected in parallel
with the load, for
protection against
voltage transients.
Max load =
<100mA
Max voltage
= 24V DC
