Open Collector Outputs (
OPEN COLLECTR
)
The meter is equipped with two NPN open collector outputs that may be set up for pulse outputs, alarms,
timed pulses, total reset, or disabled.
Pulse outputs can be set to transmit the rate, total, or grand total. Output 2 may be used to generate a
quadrature output based on the other open collector output. An output test mode is also selectable to
generate pulses at a constant programmable frequency.
Alarms are available based on the PV value or the digital input. The alarm status will show on the display
even if the output is not wired.
A timer output (
TIMER
) turns the open collector on and off at the specified time intervals. The timer can
be set as single-shot or continuous timer.
A total reset output generates a pulse whenever the total is reset, regardless of the reset method used.
The On time is programmable between 0 and 9,999 seconds.
The stopwatch output (
STPWATCH
) allows the open collector to be manually activated by starting the
stopwatch. The stopwatch count can be displayed on the top or bottom line.
The output may be disabled by selecting
DISABLE
.
