- 16 outputs 8 V to 36 V
- 500 mA output current per channel
- Thermal and short-circuit protection
- Load on supply voltage
- Optical isolation
The mezzanine card M27 with its open-collector outputs can be used in process I/O applications (cf. M28 with open-emitter outputs). If there are currents of above 500mA an intelligent power switch guarantees that the respective transistor is switched off. The M-Module is equipped with suppressor diodes for protection against overvoltage caused by inductive loads. The output registers can be read back.
The M27 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.
