The AM16/32B multiplexer significantly increases the number of sensors that can be measured by a Campbell Scientific datalogger. It interfaces with the datalogger and adds terminals for wiring additional sensors of almost any type.

Benefits and Features

Significantly increases the number of sensors the datalogger can measure
Multiplexes up to 32 sensors at a time
Supports many types of sensors including thermistors, potentiometers, strain gages, vibrating wires, reflectometers, and soil moisture blocks
Decreases the cost of cabling individual sensors on long wire runs
Allows a relay address to be used to go directly to a specific channel—reducing power consumption and wear on the relay switches
Protects the equipment from electrical surges by including gas tubes on all of the inputs and having a ground lug
Prevents sensor-cable damage by providing strain relief for sensor leads and independent routing for sensor shield lines
Eliminates the requirement for dc blocking capacitors for gypsum soil moisture blocks, significantly reducing sensor cost
