Overview
The AM16/32B multiplexer significantly increases the number of
sensors that you can measure with a Campbell Scientific data logger. It
interfaces with the data logger and adds terminals so that you can wire
additional sensors of almost any type.
Benefits and Features
-
Significantly
increases the number of sensors the data logger can measure
-
Can multiplex 16,
32, or 48 sensors
-
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
-
Electrical surge
protection via gas tubes on all analog I/O, and varistors or TVS diodes on
all other connections
-
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
