M9135A PXI 20-ch SPST switch
M9135A specifications and characteristics
For your high power switching needs, the M9135A module
provides 20 channels of single-pole, single-throw (Form A)
relays suitable for switching inductive or capacitive loads. The
module design consists of heavy-duty armature relays rated
for resistive loads up to 300 W DC or 1250 W AC. Applications
benefiting from this module include switching of heavy AC
or DC loads, power supplies, and large system relays and
solenoids. Connect to the front panel using the 20-pin MS-M
connector or cable.
