Applications

The D2600 frequency input module is part of the DGH’s D2000 sensor to computer interface data acquisition module family. This input module is an enhanced version of the D2600 module with added programmable functions. Similar to D2600, this module converts the frequency or pulse sensor input signal to digital data, linearises, scales and communicates the values using the ASCII protocol to give digital output. The D2600 series includes frequency, timer, 60H events counter (20Hz available upon request) and accumulator (combination of frequency/timer with events counter) models. The D2600 frequency input module also contains a digital input (acting as the events counter on 160x and 161x modules). For extra security, it utilises a non-volatile EEPROM (Electrically Erasable Programmable Read Only Memory) to store all user-selectable settings and programmed features, meaning the values are maintained in the event of power loss (this feature excludes the events counter – upon power-up the counter is set to 0). The D2600 comes pre-set with default values of 300 baud, one start bit, eight data bits, one stop bit, no parity and any address recognised, but these values can be easily changed by the user. The modules are designed to be compatible with all popular computers utilising RS-232C or RS-485 ports and no software is necessary to start using them, although the utility software is provided. The D2600 can be mounted on a DIN-rail if required (MK-1 mounting kit required) and can be combined with other D1000/D2000 modules to provide complete customised data acquisition system for given application.

  • Analog-to-digital frequency input module
  • Additional programmable features – built-in commands to create custom input-to-output (nonlinear) functions, with ASCII output scaled to desired engineering units and straight-line segment approximation of up to 24 segments
  • Choice of RS-232 or RS-485 output
  • Choice of inputs: Frequency (1Hz to 20kHz), Timer (100μs to 30s), Events counter (60Hz) or Accumulator (1Hz to 10kHz or 100μs to 30s, with the events counter)
  • User selectable settings include switching level (0V or +2.5V), adjustable hysteresis (1mV to 1V), baud rate and parity type
  • Communicates using ASCII protocol
  • Accuracy: ±0.01% of reading, ±10μs for timer models or ±0.01Hz for frequency models
  • Resolution: ±0.005% of reading, ±0.01μs for timer models or ±0.01Hz for frequency models
  • Input Impedance: 1MΩ minimum
  • Input protection to 250Vac
  • Span temperature coefficient: ±20ppm/°C for frequency and timer models
  • 1 Digital input (or Events counter for 160x and 161x models)
  • Pulse count of up to 10 million positive transactions on models with the events counter
  • Power requirements: Serial = 0.75W
  • Temperature range -25°C to +70°C

The applications for the D2600 data acquisition modules include:

  • Process monitoring and control
  • Remote data logging to any host computer
  • Product testing
  • Direct connection to modems
