AM32 MULTIPLEXER MANUAL
1.0 FUNCTION
The AM32 multiplexer increases the number of
sensors that may be scanned by the CR10(X),
21X, and CR7 dataloggers. Sensor leads are
connected to the AM32. Mechanical relays are
used to switch the sensor signal(s) to a cable
connected to the datalogger. Two lines are
switched simultaneously; a maximum of 32 sets
of 2 lines (32 channels) may be scanned.
Signals from analog sensors are multiplexed
into either a single-ended or a differential
channel. For a discussion of single-ended
versus differential analog measurements,
please consult the Measurement Section of
your datalogger manual.
