3.5 Audio Output
This is a 3.5mm Jack socket mounted on the rear panel and labelled
AUDIO
. It is
used to connect headphones, wireless headsets or an external speaker so that
audio tones generated in some of the modes can be heard. e.g. Leak checking tone
and audio alarms. The minimum load impedance should be 8 ohms and the power
handling is 2 watts max.
3.6 Analog I/O Connector
The Analog Input / Output connector is a 15 way D-Type socket mounted on the
rear panel of the HPQ2-IP unit and labelled
ANALOG I/O
. It consists of;
one analog output 0 to +10V and four quasi-differential analog inputs 0 to
±
10V
with a maximum voltage on the return of
±
0.5V.
±
15V power outputs both fused at 100mA, fuses are self resetting.
