The DPF9300 digital input
panel meter offers many features
and performance capabilities to
suit a wide range of industrial
applications. The DPF9300 offers both
counting and rate in the same
package. The
optional plug-in output cards allow
the opportunity to configure the
meter for present applications,
while providing easy upgrades for
future needs. The meters employ
a bright 14 mm (0.56") LED display.
The intensity of the red LED display
can be adjusted from dark room
applications up to sunlight readable,
making it ideal for viewing in bright
light or dark room applications. The meters
accept digital inputs from a variety
of sources including switch
contacts, outputs from CMOS or
TTL circuits, magnetic pickups and all standard RLC sensors. The
meter can accept directional, unidirectional
or quadrature signals
simultaneously. The maximum input
signal varies up to 34 KHz
depending on the count mode
and function configurations
programmed. Each input signal
can be independently scaled to
various process values. The rate
meters provide a MAX and MIN
reading memory with programmable
capture time. The capture time is
used to prevent detection of false
max or min readings which may
occur during start-up or unusual
process events. The meters have
four set point outputs, implemented
on plug-in option cards. The plug-in
cards provide dual FORM-C relays
(5A), quad FORM-A (3A), or either
quad sinking or quad sourcing open
collector logic outputs. The setpoint
alarms can be configured to suit
a variety of control and alarm
requirements. Communication and
Bus capabilities are also available
as option card through the bus.
Additionally, the meters have a
feature that allows a remote
computer to directly control the
outputs of the meter.
With an RS232 or RS485
card installed, it is possible to
configure the meter using free
software.
The configuration data can be
saved to a file for later recall. A
linear DC output signal is available
as a plug in option card. The card
provides either 20 mA or 10V
signals. The output can be scaled
independent of the input range and
can track any of the counter or rate
displays.
Once the meters have been initially
configured, the parameter list may
be locked out from further
modification in its entirety or only
the set point values can be made
accessible. The meters have been
specifically designed for harsh
industrial environments. With
NEMA 4X (IP65) sealed bezel and
extensive testing of noise effects
to CE requirements, the meter
provides a tough yet reliable
application solution.

Response Time: 6 msec. typical; function dependent. Certain resets, stores and inhibits respond within 25 ìsec if an edge occurs with the associated counter or within 6 msec if no count edge occurs with the associated counter. These functions include CtrStL, CtrStE, HLrStL, HLrStE, INHlbt, StOrE, and PrNsSt. Once activated, all functions are latched for 50 msec min. to 100 msec max. After that period, another edge/level may be recognized

DUAL COUNT MODES When any dual count mode is used, then User Inputs 1 and/or 2 will accept the second signal of each signal pair. The user inputs do not have the Logic/Mag, High/Low Freq, and Sink/Source input setup switches. The user inputs are inherently a logic input with no low frequency filtering. Any mechanical contacts used for these inputs in a dual count mode must be debounced externally. The user input may only be selected for sink/source by the User Jumper placement.
