The Keysight N2261A is a 40-channel general-purpose relay switch module delivering independent signal routing control through 40 Single Pole Single Throw (SPST) latching relays. Each channel switches signals up to 200 V, 1 A, and 60 W or 62.5 VA, accommodating diverse signal-switching requirements across DC, AC, and mixed-signal test environments. The module integrates relay cycle counters for maintenance tracking and supports up to 10 simultaneous channel switching operations.
