M37N - Mezzanine Card with 4 Analog Outputs, 16 Bits

The mezzanine card M37N is a high-precision M-Module with four analog voltage, or alternatively current output channels for very fast signals. The output voltage range for each channel is -10 to +10 V. The current outputs are separately available and canbe used as 0 to 20 mA outputs. The M-Module comes with 16 bits resolution at an ultra-high voltage accuracy of +/-0.1% which is valid for the complete temperature range from -40 to +85°C. Beyond that it is optionally possible to even extend these values by additional calibration.

The M37N supports a load resistance of 600 Ohms and more. The isolated supply voltages can be generated on the board by two low-noise DC/DC converters. The output load is driven to ground.

The M37N is designed for a large range of applications, for example in an automated test environment, in process control systems or for sensor measurements.

The M37N 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.
