Line In Standard Line In: (0dB) Vrms=1V
Line Out Headphones with 20mW @ 16 Ohm or 32 Ohm.
Audio inputs as a Line Out function to 10k Ohm impedance of receiver. Audio
level while connected to 10k Ohm equals -10dbV

max. length for cables: 50m
OUT

Output may be loaded with max. 50mA
n
max. length for cables: depends on loop impedance of the connected
cable.
Example: switching an LED light using the P7 outputs
The outputs in the M73O Interface board are using an optocoupler with an open collector.
These outputs will require the use of an external DC power supply up to 50 volts with a pull-up resistor and
support a maximum current of 10mA. They are not capable of dry connect closure or direct use with AC
power.
The example shows a simple low voltage low current application such as switching an LED light using the P7
outputs.
