Digital Inputs

Figure 5–1: Digital Inputs Screen
A. Lit bargraph indicates that the input is
ON. For analog inputs or outputs, the
bargraph indicates the output
percentage.
B. S1 is common to all meters and
represents standard digital input.
C. A-S1 and A-S2 represent I/O point
numbers on the first (A) module.
D. Use the arrow buttons to scroll through
the remaining I/O points. Point numbers
beginning with "B" are on the second
module. See Table B–3 on page 209 for
a complete list of I/O point numbers.

The meter includes one solid-state digital input. A digital input is used
to detect digital signals. For example, the digital input can be used to
determine circuit breaker status, count pulses, or count motor starts.
The digital input can also be associated with an external relay. You
can log digital input transitions as events in the meter's on-board
alarm log. The event is date and time stamped with resolution to the
second. The meter counts OFF-to-ON transitions for each input. You
can view the count for each input using the Digital Inputs screen, and
you can reset this value using the command interface. Figure 5–1 is
an example of the Digital Inputs screen.
