The mezzanine card M81 is a 16-channel fully isolated, fully protected digital output M-Module for industrial applications. The outputs can switch DC as well as AC voltages and can also be used for analog signals. The M81 works with parallel transmission and supports very fast, spike-free switching.
The M81 switches relays, lamps or other loads. Typical I/O applications include automated test equipment, simulators and PLC-like applications.
The M81 is software-compatible with M27.
The M81 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.
