Up to 96 differential channels per full rack mainframe  Constantly monitor input signals for fault conditions  Flexible configurations for detecting edges, out-of-bounds conditions and measuring pulse widths  Inputs can be masked, inverted, and combined to produce interrupts  Can be used as a time stamp module and as a digital I/O  Programmable debounce circuitry prevents erroneous readings  10 V and 100 V input ranges  On-board memory stores events with IEEE 1588 timestamps  Synchronize reading of input states with other scanned analog channels
