Agilent N2263A 32-Bit Digital Input/Output Module

The Agilent N2263A 32-Bit Digital Input/Output Module delivers 32 bidirectional I/O lines plus three dedicated handshake control lines for automated test systems. This plug-in module configures as a single 32-bit port, four independent 8-bit ports, or two independent 16-bit ports—all addressable on a byte-by-byte basis. Each I/O channel incorporates Zener diode input protection rated to 42 VDC and on-channel ESD protection, enabling direct interfacing with high-voltage/high-current devices including relays, microwave switches, and solenoid coils.
