Introduction

The M24 has voltage-sensitive inputs. Either 16 channels are available using a 25-pin D-Sub connector, or 8 channels using a screw terminal with LED display. The nominal switching threshold is half the supply voltage. Suppressor diodes protect all inputs against overvoltage. Interrupt generation can be programmed for each individual channel on each transition.

The M24 is a high-end M-Module™ for process input. It is designed for use in critical applications. The M24 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.
