Introduction

The M32 is a 16-bit binary input M-Module™ with latching and comparator capabilities for industrial applications. The inputs are optically isolated with a high isolation voltage of 500V DC. A current limit for each input guarantees a wide input voltage range of 0 to 155V. Each input signal edge generates a maskable interrupt for each channel.

The signals of mechanical switches are debounced by a digital circuit. The precision debouncing time of 300ns to 100ms is software programmed in a PLD.

The M32 has its input load on supply voltage which means that switching an input to ground activates the respective optocoupler.

The M32 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.
