Keysight (Agilent) U2652A 64 Input USB Modular Digital I/O

The Keysight U2652A is a 64-channel opto-isolated digital input module that delivers high-density signal acquisition over USB 2.0. Designed for industrial and laboratory automation, it interfaces with 10 to 24 V digital signals while providing 1250 Vpeak / 1250 Vrms transient protection. The module connects via Hi-Speed USB 2.0 at 480 Mbps and includes an on-board isolated +5 V power supply (150 mA typical output). It operates as a standalone unit or within a modular system, supporting SCPI and IVI-COM standards for broad platform compatibility. An interrupt function automatically triggers system alerts on digital state changes, while virtual port grouping enables logical channel organization. The U2652A ships with Keysight BenchVue software license and Measurement Manager, simplifying test automation and instrument control across Keysight VEE, MATLAB, NI LabVIEW, and Microsoft Visual Studio environments.
