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) 10 to 30 VDC External Power + Supply V V 5 to 30 VDC External Power + Supply – VSUP (Count 0) C V C – C VSUP (Count 0) VSUP (Out 0) VSUP (Out 0) VSUP (Ch 0) Sourcing-Output Output Device Circuitry Powered by cFP-CTR-500 0) VV SUP (Ch IN (Count 0) Input + Load Circuitry – VOUT (Ch 0) COM COM (Ch(Count 0) 0) VOUT (Out 0) 5 to 30 VDC External Power Supply (Optional) SinkingInput Device SinkingOutput Device VIN (Count 0) Input Circuitry Load VOUT (Out 0) COM (Out 0) COM (Count 0) COM (Out 0) VSUP (Out 1) VSUP (Count 1) VSUP (Out 1) VSUP (Ch 1) Output Circuitry 1) Load VIN (Count COM (Ch 1) 1) Input Circuitry COM (Count 1) VV (Ch n) SUP SUP (Gate Output Switch Circuitry 0) VOUT (Out 1) SinkingInput Device SinkingOutput Device VIN (Count 1) Input Circuitry VOUT (Out 1) COM (Out 1) COM (Count 1) COM (Out 1) VSUP (Out 2) VSUP (Gate 0) VSUP (Out 2) Powered Load + SourcingOutput Device VV (Ch(Count 1) SUP SUP VOUT (Ch 1) External Power Supply – VSUP (Ch n) VIN (Gate VOUT (Ch n) 0) Load Input Circuitry VOUT (Out 2) COM (Ch n) COM (Out 2) COM (Gate 0) SinkingInput Device VIN (Gate 0) Switch Input Circuitry VOUT (Out 2) SinkingInput Device COM (Out 2) COM (Gate 0) To next channel cFP-DO-403 To next channel To next channel cFP-CTR-500 cFP-CTR-502 Wiring Schematics for Counter Modules Ordering Information NI cFP-CTR-500....................................................................777318-500 NI cFP-CTR-502....................................................................777318-502 Recommended Compact FieldPoint System Products NI cFP-2020 ......................................................................777317-2020 NI cFP-BP-4 ............................................................................778617-04 NI cFP-CB-1............................................................................778618-01 NI PS-5 power supply............................................................778805-90 NI Developer Suite Professional Control Edition..................777906-03 BUY NOW!
