Agilent/Keysight Z2404B

The Agilent/Keysight Z2404B is a C-Size VXIbus module that delivers 64 isolated digital input channels for high-density signal acquisition and edge detection. Configurable as four 16-bit ports, it provides interrupt-driven monitoring with programmable debounce, edge selectivity, and flexible input thresholding from 5 V to 48 V. Each channel withstands 115 Vac RMS or 115 Vdc ground potential difference, making it suitable for industrial and laboratory test applications requiring galvanic isolation and reliable state capture.

– Technical Specifications

• Module Type: Register-based VXIbus, C-Size, 1-Slot form factor
• Digital Input Channels: 64 isolated channels organized as four 16-bit ports
• Channel Isolation: Full electrical isolation between channels, power, and ground (115 Vac RMS or 115 Vdc withstand voltage per channel)
• Input Threshold: Jumper-selectable logic levels from 5 V to 48 V
• Interrupts: 64 available, maskable and edge-selectable (positive, negative, or both polarities)
