Axiom SDI-AM Analog Module

The Axiom SDI-AM Analog Module is a flexible expansion interface that is compatible with a wide variety of analog sensors and any SDI-12 compliant datalogger / DCP such as the Axiom. It essentially allows compliant dataloggers to connect to virtually any digital (native SDI-12 support) or analog (via the SDI-AM) sensor, and control power to a wide range of devices (ex. pumps, cameras, actuators, etc.)

The SDI-AM includes four individually configurable analog input channels; two switched 12V power supply outputs, two individually configurable, stable, excitation voltage outputs and a general purpose counter input. The electronics are enclosed in a rugged aluminum case to provide a compact and waterproof enclosure that includes standard FTS shoulder bolts for quick installation on our unique keyway plates. Electrical connections are made by easy to use spring clip terminal strip connectors.

As an SDI device, it has a configurable SDI address and is powered by +12VDC from a datalogger's SDI-12 bus. Normally the module is connected to an SDI port of a data logger; however, the sensor may also be connected to any SDI-12 compliant controller.

SDI modules can be used in multiples to provide a maximum of interface flexibility with a large number of analog sensors.

The SDI-AM is fully configurable through the Axiom's touchscreen display.
