Analog Outputs
The ADS TRITON+ (with an ADS XIO) can provide synchronous
or real-time depth, velocity, and flow rate measurements to up to
two third-party systems or devices via 4-20mA analog output
signals. The most common use for analog outputs is to provide
flow and depth information to SCADA systems via input to Remote
Terminal Units (RTUs) or Programmable Logic Controllers (PLCs).
However, other uses include other meters, totalizers, samplers, and
display equipment.
To configure the monitor to properly deliver the signals to these
third-party devices, you must configure the ADS Qstart software
with the signal scale and engineering units equivalent to the signals
transferred.
Connecting a Third-Party Device to an Analog
Output on the XIO
Perform the following procedure to connect each third-party device
(up to two) to an analog output 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. Verify that the instrument or equipment that will be receiving
the analog signals has been set up to accept the signal wiring.
Setup may involve penetrating existing enclosures, running
conduit, or sealing glands.
2. Establish the range and engineering units representing 4 to
20mA for the analog output, and then configure the Analog
Output 1 (or 2) component of the XIO Device through Qstart
