The Agilent/Keysight N2293A is a screw terminal block connection accessory designed to interface the N2263A 32-bit TTL Digital I/O Module with external wiring. It provides organized, field-wireable connection points for all digital I/O lines and handshake/control signals, eliminating the need for custom cabling harnesses. The N2293A itself is a passive termination interface—it carries no active circuitry or independent measurement capability—but delivers a critical link between laboratory equipment and the module’s 32 configurable I/O lines.
Technical Specifications
