20-channel Solid-state
Differential Multiplexer
The Model 7710 plug-in module offers 20 chan-
nels of 2-pole or 10 channels of 4-pole relay
input that can be configured as two independent
banks of multiplexers. The relays are solid state,
providing long life and low maintenance. Solid-
state relays usually have 100 times longer life
than mechanical relays. It is ideal for long-term
data logging applications as well as for demand-
ing high-speed applications.
