M62N - Mezzanine Card with 16 Analog Outputs, 15/16 Bits

The mezzanine card M62N is an analog output device with as many as 16 channels on one single M-Module. The isolated supply voltages are generated by an on-board DC/DC converter. The output voltage range is programmable to 0 to 10 V or -10 to +10 V. Alternatively, current outputs are available within a range of 4 to 20 mA. The output load is driven to ground.

For driving more than 6 current outputs at the same time an external supply is needed!

The M62N 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 MEN or other manufacturers.
