Keysight/Agilent N2291A Screw Terminal Block
The Keysight/Agilent N2291A Screw Terminal Block functions for a GP relay that is a programmable switching device. It provides 40 independent SPST latching relay channels for signal control and operates with a terminal block for external wiring integration. The screw terminal block unit enables controlled routing of electrical signals in automated test environments. Each channel within the module supports high switching that is rated up to 200 volts.
Each relay channel supports a maximum current rating of 1 ampere under specified conditions. The power handling capability reaches 60 W or 62.5 VA per channel for safe and repeatable switching performance. The N2291A screw module uses latching relays that maintain state without continuous coil excitation. The architectural design of N2291A terminal unit reduces power consumption and improves thermal stability during extended system operation cycles. The architecture supports high-speed switching when multiple channels operate in parallel mode. The N2291A screw terminal block supports simultaneous activation of up to 10 switching channels without exceeding defined operational constraints. It allows single-channel switching with break-before-make functionality.
The terminal block also supports multiple channel open and close operations for synchronized signal routing tasks. This capability enables flexible switching sequences required in complex instrumentation and validation systems. The paired signal switching is achieved by using two channels across two separate N2291A modules. This configuration allows coordinated switching of differential or related signal paths within measurement systems. The architecture supports scalable system expansion by combining multiple modules within a unified control framework. Each module operates independently while maintaining synchronization through system-level control interfaces. The N2291A screw terminal block supports wire sizes ranging from 18 to 26 American wire gauge. Wires smaller than 18 gauge must be bundled within 4 inches of the terminal interface. It allows reliable mechanical retention and stable electrical contact during system operation.
The screw terminal block includes built-in cycle counters for each switching channel. The counters track operational usage and support predictive maintenance planning for long-term reliability. Cycle count monitoring allows users to identify heavily used channels and schedule timely replacements.
