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
