Agilent 34903A
20-Channel Actuator/
General Purpose Switch
• SPDT (Form C) latching relays
• 300 V, 1 A actuation and control
This general-purpose switch module
has 20 independent single-pole, dou-
ble-throw (SPDT) relays. Use it to
cycle power to products under test,
control indicator and status lights,
and to actuate external power relays
and solenoids. Combine it with
matrix and multiplexer modules to
build custom switch systems. Its
300V, 1A contacts can handle up to
50W, enough for many power line
switching applications.
Agilent 34904A
4x8 Two-wire Matrix Switch
• 32 two-wire crosspoints
• 300V, 1A switching
The 34904A gives you the most flexi-
ble 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 multiple modules to build
8x8, 4x16 or larger matrices, with up
to 96 crosspoints in a single frame.
