Keysight / Agilent / HP N2291A Screw Terminal Block

The Keysight/Agilent/HP N2291A Screw Terminal Block is a connection accessory engineered to facilitate external signal wiring to the N2261A 240-Channel General Purpose Relay Module and compatible test instrumentation. This terminal block delivers organized, secure termination of external circuitry within automated test equipment (ATE) systems, eliminating the need for custom wiring solutions.

Technical Specifications The N2291A features multiple screw terminals for wire termination and integration with Keysight/Agilent relay modules and measurement systems. While voltage and current specifications are not detailed for the terminal block itself, the associated N2261A 240-Channel module operates within the broader Agilent 3499 series framework, which includes relay specifications of 1 A per channel and 4 A per module for armature latching relays.

Key Features

Screw terminal design for secure external signal connections

Direct compatibility with the N2261A 240-Channel General Purpose Relay Module

Integration with Agilent 3499 series architecture for expandable test systems

Extends approximately 8.5 cm beyond mainframe rear for accessible termination

Supports armature latching relays with proven electrical life specifications

Typical Applications The N2291A terminal block serves instrumentation requiring organized external signal distribution in ATE environments. Applications include relay switching networks, multiplexed signal routing, and general-purpose switching matrices where clean, maintainable connections are essential.

Compatibility & Integration Designed specifically as an accessory for the Keysight N2261A 240-Channel General Purpose Relay Module, the N2291A integrates within Agilent 3499A/B/C mainframes. It operates alongside compatible plug-in modules including multiplexers (N2260A, N2266A) and digital I/O modules, providing a modular foundation for complex signal switching and measurement architectures.
