Introduction
The SDI-12 AnalogPlus module has 5 ports to take measurements from vast variety of sensors and transfer
the results to a data recorder. Three of them (AN1, AN2, AN3) are exclusively for analog measurements, one
(DIN) is exclusively for digital measurements, and AN4 can be used for analog as well as logic level driven
digital measurements.
Features
High accuracy & excellent stability
Four Analog inputs with
o
Can be configured for Single-ended or Differential voltage measurements
o
Reference voltage output for ratiometric sensors (bridges and potentiometers)
o
24-bit A/D converter
o
0-5V input range
o
Programmable gain (1 to 128) user specified or Automatic gain
o
Simultaneous 50Hz and 60Hz noise rejection.
One digital input with selectable pull-up (or pull-down) to support switch closure type inputs.
Additional digital input for 0-5 V signals (shared with Analog channel 4).
Frequency measurement : 1 Hz to 8 kHz
Counts measurement
Quadrature Shaft Encoder measurement
Programmable switch de-bounce times to prevent multiple counts on a single event.
Programmable switched 5 volts and 12 volts output
