Analog and Digital I/O 9-3
Analog Inputs
The TRITON+ (with an ADS XIO) supports the monitoring of up
to two analog 4-20mA signals from other instruments. These
signals typically represent measurements made by other devices,
such as flow meters, pressure sensors, or level transducers. To
properly configure the monitor to process the signals received from
these third-party devices, you must configure the ADS Qstart
XML
software with the signal scale and engineering units equivalent to
the signals received.
Connecting a Third-Party Instrument to an
Analog Input on the XIO
Perform the following procedure to connect each third-party
instrument or device (up to two) to an analog input terminal on the
ADS XIO:
Note: Make sure external power is available, but not
turned on, to the monitor before connecting the signal
wiring. If it is not available, you cannot complete testing,
which may require return visits by the owner
representative and/or electrician or instrument technician
for wiring problems.
1. Determine the location at which to connect to the analog
signal wiring. Make sure the distance from the signal
source to the XIO unit is as short as possible and avoid any
cable runs that would run parallel to switching panels or
other control components. These can create electrical
noise that will interfere with the signal and create false
readings.
