M82 - Mezzanine Card with 16 Digital 20 kHz Inputs

The mezzanine card M82 is a 16-channel fully isolated input M-Module with latching and comparator capabilities for industrial applications. A current limit for each input guarantees an input voltage range of 0 V to 40 V. Each input signal edge generates a maskable interrupt for each channel. The voltage-sensitive inputs have a hysteresis function.

Typical I/O applications include automated test equipment, simulators and PLC-like applications with different voltage requirements.

The M82 is software-compatible with the M31.

The M82 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.
