34903A
20-Channel Actuator/General Purpose Switch
• SPDT (Form C) latching relays
• 300 V, 1A actuation and control
This general-purpose switch module has 20 inde-
pendent single-pole, double-throw (SPDT) relays.
Use it to cycle power to products under test,
control indicator and status lights, and to actu-
ate external power relays and solenoids. Combine
it with matrix and multiplexer modules to build
custom switch systems. Its 300 V, 1A contacts can
handle up to 50 W, enough for many power line
switching applications.
34904A
4x8 Two-wire Matrix Switch
• 32 two-wire crosspoints
• 300 V, 1A switching
The Agilent 34904A gives you the most flexible
connection path between your device under test
and your test equipment, allowing different instru-
ments to be connected to multiple points on your
DUT at the same time.
Rows or columns may be connected between mul-
tiple modules to build 8x8, 4x16 or larger matrices,
with up to 96 crosspoints in a single frame.
