General Purpose Switch Modules
This User’s Guide covers the following two plug-in modules for the Agilent
34980A Multifunction Switch/Measure Unit:
• The 34937A provides independent control of 32 relays, including:
• Twenty-eight Form C relays, each rated for 1 A at 60 W per channel
• Four Form A (SPST) relays, each rated for 5 A at 150 W per
channel.
• The 34938A, for power switching applications, offers 20 Form A relays,
each rated for 5 A at 150 W per channel.
• The 34939A provides independent control of 64 Form- A relays, each
rated for 1 A at 60 W per channel.
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.
