Keithley 7700 20 Channel Differential Multiplexer Module Keithley's 7700 plug-in module, featuring 20 channels of 2 pole or 10 channels of 4 pole multiplexer switching has the ability to be configured as 2 independent multiplexers. General purpose measurement is made possible with the 20 channels, whilst current measurement is available through 2 additional protected channels. No other accessories are needed to make thermocouple temperature measurements due to the automatic CJC provided. Bandwidths of up to 50MHz are enabled as the 7700 contains latching electromechanical relays.

Applications include: RTD, thermocouple temperature and thermistor. Features and Benefits: • 50MHz bandwidth
• 3A capacity for current channels
• Relay closures store in onboard memory
• Oversize screw terminal for easier connection
• <3ms actuation time
• 300V, 1A capacity for voltage channels What is a Multiplexer Module? Also known as a mux or data selector, a multiplexer device is used to forward multiple digital and analog input signals in to one single output. in forwarding multiple signals in to one output, a multiplexer allows several signals to share one device. Demultiplexers or demux operate in reverse, they are often used for cost reduction in conjunction with one another, often within communication and data links.
