The Keysight 34939A is a high density general-purpose switch module for the 34980A Multifunction Switch/Measure Unit. It has 64 independent single-pole, single-throw (SPST) relays that can switch 1 A and carry 2 A. This module can be used to cycle power to products under test, control indicator and status lights, and to actuate external power relays and solenoids. The relays are 100 V, 1 A contacts and can handle up to 60 W. Standard 78-pin Dsub connectors allow for use with standard cables, screw terminal blocks, or mass interconnect solutions.
