Description
Spec
Electrically connected in parallel with the con-
nector for the power supply, this pin provides an
auxiliary connector for mains 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
Ground
Description
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
transient voltages.
Max load = <100mA
Max voltage = 24V
DC (to the
transistor)
Connect to GND to activate, or leave floating (or
unconnected) to deactivate.
Must not be
exposed to
voltages greater
than 30V DC.
