The Keithley 7710 20-channel Solid-state Differential Multiplexer is a plug-in module which offers 20 channels of 2-pole or 10 channels of 4-pole relay input that can be configured as 2 independent banks of multiplexers. The relays are solid state, providing long life and low maintenance (solid state relays usually have a life some 100 times longer than that of mechanical relays). The 7710 is used for long-term data logging applications as well as for demanding high-speed applications and is used with Keithley systems 2700 ( 760-0354 , 7600357 ), 2701 ( 760-0351 ) and 2750 ( 760-0360 ).
