Technical Description

Depending on sensor type, the AM16/32B can multiplex 16, 32, or 48 sensors. Up to six AM16/32Bs may be connected to the same datalogger, depending on the number of control ports and analog inputs available.

The AM16/32B either multiplexes 16 groups of four lines (a total of 64 lines) through four common (COM) terminals, or multiplexes 32 groups of two lines (also a total of 64 lines) through two COM terminals. A cable connects the common terminals to datalogger analog inputs, excitation channels, or ground as required by the sensor. The datalogger controls the multiplexer using two control ports or one control port and one excitation channel.

AM16/32B Specifications

  • Power: 9.6 to 16 Vdc
    (under load)
  • Current Drain (typical)
    Quiescent: < 210 µA
    Active: 6 mA
  • Reset Levels
    Inactive: < 0.9 V
    Active: 3.3 to 8 V
  • Scan Advance: Occurs on the leading edge of the clock pulse transition (from below 1.5 V to above 3.3 V)
  • Minimum Clock Pulse Width:
    1 ms
