The CR6 is equipped with many new innovative features that allow more functions and applications than ever before. Among the most diverse of these new features are the universal terminals that allow every measurement channel to be used for virtually any sensor (analogue, digital or smart). The CR6 knows what measurement to perform on each of the twelve U Terminals by declarations in the program operating on the data logger and can be software configured.

Analog functions consist of:

  • Analog inputs: 12 single-ended or 6 differential with ±5000 mV, ±1000 mV, ±200 mV ranges 24 bit ADC
  • Analog outputs: ±2.5 V or ±2.5 mA ranges for bridge measurements 12 bit DAC
  • Static frequency-analyzed vibrating wire: terminal pair both excites to 12 V p-p and 100 Hz to 6.5 kHz and reads vibrating wire transducers using our patented spectral-analysis technology (VSPECTM)
  • Thermistor: completion resistor internal 5 kΩ
  • Period average: up to 200 kHz, amplitude dependent
  • Low level ac: 1 Hz to 20 kHz, amplitude dependent

Digital I/O functions consist of 5 V or 3.3 V logic levels for:

  • General status/control
  • Voltage source: 5 V, 3.3 V, 20 mA @ 3.5 V
  • Timer I/O
  • Switched closure (150 Hz) or high frequency counter (1 MHz)
  • Pulse width modulation
  • Interrupts
  • SDI-12 and SDM
  • Serial asynchronous communication Tx/Rx pairs
