Analog Outputs
The (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

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
Note:
Connecting the third-party device to the XIO
requires a customer-supplied cable. ADS recommends 18-
to 20 gauge, shielded, twisted-pair standard control cable.
Consider using
Alpha Wire
™
M213202 SL005 or
General Cable
™
C7106A.41.10 cable. For more
information, contact ADS Client Services.
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
