Agilent/Keysight N2293A

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 has 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

• I/O Interface: 32-bit bi-directional TTL-compatible lines


• Control Lines: 3 handshake and control lines


• Output Compatibility: TTL-compatible or open collector output rated to 42V


• Input Protection: Zener diode over-voltage protection (>42 VDC) and ESD protection on each channel


• Configuration: Byte-by-byte configuration; individual addressability; two 16-bit port configuration; four independent 8-bit port configuration


• Connector Type: Screw terminals

Key Features

• Field-termination screw block provides flexibility in external circuit integration


• Direct interface to N2263A module with no signal conditioning or conversion


• Supports TTL input with TTL output or open collector output to 42V


• Per-channel voltage protection for over-voltage conditions exceeding 42VDC


• ESD protection integrated on all signal channels


• Multiple I/O configuration options accommodate diverse control logic requirements

Typical Applications

• Digital control and monitoring in VXI test systems


• TTL-level signal routing and distribution


• Open collector switching applications requiring voltages up to 42V


• Multi-port digital I/O expansion for automated test equipment (ATE)


• Field-wired integration in modular instrumentation platforms

Compatibility & Integration The N2293A connects exclusively to the Agilent/Keysight N2263A 32-bit TTL Digital I/O Module and is deployed within VXI system architectures. It is the mechanical and electrical interface between the N2263A and laboratory test benches or external digital systems.
