Ordering Information
7710 20-channel Solid-
state Differential
Multiplexer Module
Use with Integra Series mainframes: 2700, 2701, 2750
Differential Multiplexer
The Model 7710 plug-in module offers 20 channels 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. Solidstate relays usually have 100 times longer life
than mechanical relays. It is ideal for long-term
data logging applications as well as for demanding high-speed applications.
