Autosampler Interface Controller

SDI-12 autosampler interface controller for connecting ISCO automatic pump sampler to Axiom datalogger for water quality monitoring systems by FTS.

The unique FTS autosampler interface controller is a custom-designed interface used to communicate between the Axiom datalogger / DCP and ISCO automatic water samplers. The interface converts SDI-12 commands sent from the datalogger to an appropriate signal format to control the water sampler. It's a key component in our SedEvent event-triggered automated sampling system.

It allows the datalogger to trigger a water sample from the attached ISCO sampler and correlate the sample request to a specific sampler slot number. The interface also allows the datalogger to retrieve the slot number of the last water sample taken as well as the current SDI-12 bus voltage level.
