TM32 analog input module is intended for remote input of analog current measuring signals ranging -22 to +22 mA.

Performance data

  • 32 current channels
  • Input resistance – 110 Ohm (0.1 %)
  • Over-voltage protection – 16 V
  • Measured current range: –22…+ 22 mA
  • ADC capacity – 14 bit
  • Accuracy of measurements – 0.1 %
  • Conversion time for all channels – 1 ms
  • Galvanic isolation – 1500 V (power supply/interface lines, measurement circuits)

Main functions

  • Data input via 32 current measurement channels, measurement range is –22…+ 22 mA (calibration available via software)
  • Averaging time definition for each channel (at least 20 ms)
  • Definition of sporadic thresholds for each channel
  • Definition of substitution values for each channel
  • Calculation of output value in accordance with with user settings
  • All events (detection of module failure, modification of module`s configuration, module activation/deactivation, sporadic thresholds exceeded) are stored in the non-volatile memory

Additional capabilities

  • Archive with capacity for 660 events (detection of module failure, modification of module`s configuration, module activation/deactivation, sporadic thresholds exceeded)
  • Light indicators reporting channel status, port states, power supply/module status
  • Module`s time can be synchronized either through the central controller, or via an external GPS receiver with an accuracy of 1 ms
  • Regular self-testing of the module (monitoring of ADC operation, measurement circuits' operating voltage)
  • Built-in real time clock
