M393

8-channel 12-/16-bit differential input ADC Module

The M393 is an 8-channel differential input ADC M-Module, ideal for applications in which autonomous signal conversion is an issue, as well as in standard mid-range applications.

The M393 is a 12-/16-bit 8-channel differential input ADC M-Module, ideal for 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.

This M-Module is also available as a PCI, CompactPCI (3U and 6U) or VMEbus (3U and 6U).
