The 34938A switching module is a slot for high switching capacities in connection with the 34980A basic device from Keysight (formerly Agilents electronic measuring technology). It offers 20 independent single-pole on / off switches with a maximum switching current of 5 A. B. the supply of supply voltages to a DUT (Device Under Test) or for switching control indicators / lights or for switching external coils / inductors or high-current relays. The switching capacity for one of these contacts is 30 Vdc or 250 Vac, a switching current of max. 5 A, with a total switching capacity of 150 W, sufficient for most supply voltages.
With the standard 50-pin Dsub connector, normal cables and terminal strips can be contacted.
