Key Features & Specifications

  • 2A, 250V
  • 2-wire, latching relays
  • Provisions to add simple attenuators or filter networks
  • Screw terminal included


The Keysight 44470A multiplexed module provides ten channels to switch both high and low input signals to a common bus. It can switch signals up to 250V, 2A, and 60W, or 125VA per channel. This module exhibits low thermal offset characteristics, making it ideal for precision low-level signal routing. It can be operated in either a break-before-make mode or multiple-channels-close mode. You can make four-wire ohm measurements by programming two Keysight 44470As to open/close in a card-pair mode. A screw terminal block is provided for ease of wiring.

The 44470A, 44470D, 44471A, and 44471D are designed for low-channel count applications, with higher switching capability (current or voltage) than N2260A or N2261A modules.
