The Keysight 44471A is a 10-channel 1-wire general-purpose relay module. It can be used to control DUT power, to actuate external relay or to form an attenuator. Each relay on the module is rated for switching up to 250V, 2A, or up to 60W or 125VA. The initial closed channel resistance is lower than 1 Ohm. The 44471A exhibits low thermal characteristics, making it ideal for independent signal switching. A screw terminal block is provided for ease of wiring.
