The Keysight 34938A is a high power general-purpose switch module for the 34980A Multifunction Switch/Measure Unit. It has 20 independent single-pole, single-throw (SPST) 5 A relays. This module is used to cycle power to products under test, control indicator and status lights, and to actuate external power relays and solenoids. Its 30 VDC/250 VAC, 5 A contacts can handle up to 150 W on a single channel, enough for many power line switching applications. Standard 50-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions.
