M50 - Synchro/Resolver Converter (Product Discontinued)

The mezzanine card M50 is a 1-channel, continuous-tracking synchro- or resolver-to-digital converter with a configurable 10 to 16-bit resolution and a tracking rate of up to 1040 rps. The M-Module has a reference signal generator with a frequency range of 50 Hz to 20 kHz. Reference output voltages can be in a range of 2 Vrms to 21 Vrms. An analog velocity output can be used to monitor the rotational speed.

The M-Module is suited for nearly all synchro/resolver sensors: the user can easily adapt the M50 by plugging passive components.

The M50 is optically isolated and supplied by an on-board DC/DC converter. Optical isolation of the digitized values significantly improves accuracy compared to common transformers.

The M50 is based on the M-Module ANSI mezzanine standard. It can be used as an I/O extension in any type of bus system, i.e. CPCI, VME or on any type of stand-alone SBC. Appropriate M-Module carrier cards in 3U, 6U and other formats are available from duagon or other manufacturers.
