E8460A Datasheet, PDF (2/5 Pages) Keysight Technologies – 256-Channel Reed Relay Multiplexer

Accessories
A terminal block does not come with the module. Three
different terminal blocks are available as options: one for
crimp-and-insert connectors, one for ribbon cable
connectors, and the other for fault-tolerant protection of
DUT inputs, where each channel has a positive
temperature coefficient resistor that behaves like a
resettable fuse and will increase impedance when
excessive current is flowing in a channel.
One 2.5-in. analog bus cable (E1400-61605) is included to
connect the analog busses of multiple slot-adjacent E8460A
modules or a slot-adjacent E1411B multimeter module. The
analog bus cable, easily installed at the faceplate of the
component card, lets you connect the E8460A with the
E1411B DMM.
