This unit
The Keysight Z2404A is a 64-channel isolated digital input/interrupt module for VXIbus systems, delivering high-density signal monitoring and interrupt handling in noise-prone industrial and laboratory environments. Optically isolated inputs withstand up to 125 V rms or Vdc, while jumper-selectable thresholds and programmable debounce accommodate diverse signal conditioning requirements. The module supports four input voltage levels - 5 Vdc, 12 Vdc, 24 Vdc, and 48 Vdc - with configurable minimum thresholds of 1, 2.5, 7, or 14 Vdc and maximum thresholds of 4, 9.5, 17, or 31 Vdc. All 64 channels generate maskable, edge-selectable interrupts with two independent debounce settings for channel groups 1–32 and 33–64, ranging from 16 µs to 1074 seconds in binary increments.
