General Purpose Switch Modules

This User's Guide covers the following two plug-in modules for the Keysight
34980A Multifunction Switch/Measure Unit:
34937A
34938A
34939A
– The 34937A provides independent control of 32 relays, including:
– The 34938A, for power switching applications, offers 20 Form A relays, each
– The 34939A provides independent control of 64 Form-A relays, each rated for
All three modules utilize armature-latching relays.
You can use these general-purpose switches in your 34980A mainframe for device
actuation, digital output, signal routing, or — combined with other switch modules —
to create flexible switching topologies. You can close multiple channels at the
same time. These modules do not connect to the 34980A's analog buses.
