ZENO® 3200 Datalogger Technical Specifications

Inputs and Outputs

1. Sixteen Analog Inputs. Seven channels of differential or fourteen channels of single-ended inputs.

  • Ultrahigh Resolution: ±18-bit with 50 or 60 Hz noise rejection (sample rate up to 2 channels per second).
  • High Resolution: ±15-bit with 50 or 60 Hz noise rejection (sample rate up to 10 channels per second).
  • Medium resolution: ±13-bit (sample rate up to 50 channels per second).
  • Low Resolution: Two unipolar channels available at 12-bit A/D (on a separate fast A/D converter).
    • Accuracy and linearity for high resolution A/D converter provided over a wide temperature range as follows:
      • Linearity: ± 0.005% [-40° to +60°C].
      • Absolute Accuracy: 0.05% [-40° to +60° C].
      • Ratiometric Accuracy: ± 0.02% [+20° to +30°C] - Input range of each channel is software selectable for high resolution channels.
      • Wide Dynamic Input Range: ± 5mV to ± 5V in 10 ranges, with > 1G ohms input resistance.
    • All analog inputs are fault-protected against shorts, overvoltages, transients and ESD.

2. Digital to Analog Expansion Board

  • Up to three boards of 4 or 8 channels of individually programmable 12-bit analog output at 0 to 5 V (other output types optional).
  • Digital inputs can be configured for frequency, period, count, or event counting. Digital outputs can provide control or alarm signals.

3. 15 Digital I/O Channels

  • Six Schmitt trigger conditioned inputs.
  • Two comparator inputs.
  • Six general purpose input or output channels (Inputs TTL level with pull up resistor, outputs 0 - 5 VDC high impedance).
  • One switch closure (event counter).
  • Count Inputs: Up to 65536 counts.
  • Frequency Period Inputs: Up to 100 KHz, 0.003% accuracy.

4. Sensor and Auxiliary Power Outputs

  • Sensor Excitation: Five switched excitation outputs for software selectable voltages of 1.25, 2.50, 5.00 VDC, with accuracy of 0.01% at up to 50 mA.
  • Reference Outputs: One, fixed for sensor signal offsets.
  • Five Power Outputs (Switched): (3 at 12 volt; 1 @ 700 mA, 2 @ 150 mA, 2 at 5 volt; 2 with maximum of 600mA total for both)
  • Other Power Outputs Optional

5. Three Serial Communication Channels

  • Dedicated RS232 / RS485 / TTL level with modem control and terminal access.
  • Dedicated RS232 with optional RF modem.
  • RS232 / RS485; SDI-12 optional; two additional multiplexed TTL optional.
  • RS422
  • Up to two additional multiplexed channels.
