The Keithley 7706 All-in-one I/O Module offers 20 channels of 2-pole or 10 channels of 4-pole multiplexer switching with built-in automatic CJC sensors, together with 2 analog output channels, 16 digital outputs and one event counter/totaliser. The event counter/totaliser can, while performing mixed signal measurements, be used to monitor and control system components such as fixtures, limit switches, pass/fail indicators, external voltage sources, loads, door closures and revolutions. Applications of the Keithley 7706 include RTD, thermistor and thermocouple temperature. The 7706 is for use with Keithley systems 2700 ( 760-0354 , 7600357 ), 2701 ( 760-0351 ) and 2750 ( 760-0360 ).
