Analog and Digital Inputs and
Outputs
The ADS ® TRITON+
™
(with an ADS XIO
™
) can monitor signals
from other equipment via analog and digital inputs as well as send
signals or information to other equipment via analog and digital
outputs. The interface between the monitor and this equipment is
the ADS XIO (external input/output unit). The XIO can
accommodate up to 2 analog inputs, 2 analog outputs, 2 digital
inputs, and 2 digital outputs. It also includes an ExPAC that
provides an intrinsically-safe barrier for both external power and
communication to the monitor. External power is essential for these
input and output operations. This chapter provides general
information on how to use, configure, and connect these inputs and
outputs.
Note: Do not attempt to connect to a third-party system,
or connect/interrupt supply of a signal to another system
without an owner representative present. Under some
circumstances, these activities can disable or disrupt a
critical automated process (e.g., a pump control), cause a
dangerous condition (e.g., overpressure), or generate a
false alarm.
Note: Due to the diversity of signal sources and
frequently undocumented cabling and wiring at remote
monitoring locations, ADS strongly recommends acquiring
