The Keysight 44471A is a 10-channel general-purpose relay module that provides independent signal switching and device control within automated test systems. Each channel employs a single-pole single-throw (SPST) armature latching relay, delivering 2 A maximum current and 250 V maximum voltage per relay with a combined module capacity of 600 W or 1250 VA. The module features closed-channel resistance below 1 Ohm and thermal offset under 3 µV per channel, making it suitable for low-level mV signal switching. With 10^8 mechanical relay cycles and a maximum scan rate of 43 channels/second, the 44471A enables flexible control of device power, external relays, attenuators, and signal routing. Screw terminal block connections ensure straightforward integration into existing test setups.
