Overview
The NI cFP-CTR-50x devices are versatile, high-speed digital counter
input modules for Compact FieldPoint that you can use to count digital
signals ranging from 5 to 30 VDC and to measure frequency. These
modules are fast enough to handle input signals up to 50 kHz for
high-speed applications and flexible enough to measure frequency using
the internal frequency reference or the external gate inputs. These
powerful and versatile counter modules feature configurable lowpass
filters to eliminate high-frequency noise and cascadable counter
channels that you can use to create counters up to 128 bits wide to store
trillions of counts. For discrete control applications such as packaging,
you can configure the digital output channels to automatically energize
external devices.
All the modules include onboard diagnostics to ensure trouble-free
installation and maintenance.
Counter Modules
The cFP-CTR-500 and cFP-CTR-502 counter modules include eight 16-bit,
50 kHz counters with dedicated clock inputs. For higher resolution
counting, you can combine counter channels to provide cascaded counters
of up to 128 bits. In addition, for each counter, you can set a terminal
count at which the counter automatically rolls over or resets. For frequency
measurement, you can configure each channel to use any one of the four
gate inputs provided. In this mode, you can enable counting only when the
state of the specified gate input is logic high. By sending the digital pulse
train to the gate input and using the internal reference clock of 1 or 32 kHz,
you can measure the frequency of the incoming pulse train. Because you
can read the state of the gate input, you can also use the four gate
inputs as general-purpose digital input channels.
You can configure each of the four counter outputs to either pulse
or toggle states when you reach the terminal count for a counter input.
This is useful when you need to energize external equipment upon
reaching a particular count for applications such as packaging. You can
also use each of the outputs as general-purpose digital outputs.
The cFP-CTR-500 modules work with 10 to 30 VDC sourcing devices
and provide sourcing outputs. A sourcing device connects and
disconnects a voltage to and from the counter module. The cFP-CTR-500
uses a common ground plane for all the digital input channels.
The cFP-CTR-502 works with 5 to 30 VDC sinking devices and provides
sinking outputs. A sinking device connects and disconnects a common
terminal to and from the counter module. The cFP-CTR-502 uses a
common ground plane for all the digital input channels.
All the channels on the digital input modules feature LEDs that
indicate the input state of each channel.
Isolation
cFP-CTR-50x modules feature optical bank isolation with 2,300 Vrms of
breakdown isolation. These Compact FieldPoint modules do not have
channel-to-channel isolation.
High-Speed Counter Modules for Compact FieldPoint
Field I/O Connections
Compact FieldPoint modules include a built-in power distribution bus that provides multiple power connections on the module. A field-wired power
supply connected to the voltage (V) and common (C) terminals is internally connected to a power distribution bus that offers additional breakout
terminals for voltage supply (VSUP) and common (COM). These terminals deliver a convenient way to distribute power to field devices that require
external power.
The cFP-CTR-500 and cFP-CTR-502 have:
• 8 high-speed digital counter input terminals (VIN)
• 4 digital gate input terminals (VIN)
• 4 digital output terminals (VOUT)
• 8 common terminals (COM)
• 8 power connections to power field devices (VSUP)
