ELDIO
Detailed Description
The SoMat ELDIO eDAQlite Digital Input/Output Layer is an extremely versatile layer that supports digital input/output (I/O),
pulse counter, vehicle bus and optional GPS channels. The ELDIO layer offers eight channels that can be used as digital inputs
and outputs, four channels dedicated to wide-range inputs and six integrated configurable pulse counters. One layer can also
support up to two independent vehicle bus modules (VBM).
The digital I/O channels are grouped into three SoMat M8 female bulkhead connectors of four digital I/O channels (i.e., bits). The
eight channels on connectors |1-4| and |5-8| are individually configurable to be either inputs or outputs. The four channels on
connector |9-12| are dedicated wide-range input channels. Each connector also provides two pulse counter channels for a total
of six pulse counter channels. Vehicle bus modules are compatible with the first two connectors (|1-4| and |5-8|).
The pulse counters support pulse time period, pulse on period, pulse rate counting and quadrature decoder. The pulse rate and
quadrature decoder functions count range spans four billion counts for signals of frequencies up to 1 MHz. Pulse width period
and pulse on period functions use a 5 MHz (200 nanosecond resolution) clock. The ELDIO layer measures frequency inputs as
low as 0.0012 Hz.

Digital Output Line Equivalent Circuit
The output circuitry is applicable to the first two connectors (channels 1-8). Note that since the outputs share common I/O lines
with the digital inputs, the lines are not allowed a DC voltage level lower than -0.3 volts.
