Agilent N2267A

• Switching up to 8 A, 250 V

• Built-in overheat protection

for high reliability

The N2267A is designed for

high-current (up to 8 A contin-

uous), low-resistance switching

applications, such as AC/DC

power supply testing. It can also

be used to switch on/off AC (up

to 250 V) or DC (up to 125 V)

power supplies and current

sources. Each channel can carry

8 A current at the same time. For

thermal protection and reliability,

the N2267A has built-in temper-

ature control circuitry that uses

sensor ICs and a cooling fan. An

over-temperature warning signal

is also available to activate an

external LED or buzzer. A crimp

& insert connector (N2327A) is

available. A protection network

area is provided on the module’s

PCB, for switching inductive

loads such as electric motors,

solenoids, contacts, chokes,

electromagnets and incandescent

lamps. To protect relays from

overvoltage damage, the RC

network or the varistors must

be placed on this module, which

can effectively absorb the surge

voltage.
