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.
