12-/16-bit ADC M-module with 8x Differential inputs – M393

The M393 8-Channel Differential Input ADC M-module is very well suited to be used in applications in which autonomous signal conversion is an issue, as well as in standard mid-range applications.
A local TMS320C203 DSP provides processing capabilities to scan all channels at maximum rate, perform gain/offset compensation and store conversions results in dual-ported memory.
The M393 is available in two versions, either with voltage inputs or current inputs. The current input module has an input range of 0-20mA. The voltage input module has a programmable input range which gives great flexibility for applications in data acquisition systems that need to be able to convert a wide variety of analog voltages.
