MUX8-R2 MULTIPLEXER
Thasar S.r.l.
Description
The PalmSens series and the EmStat4X can be used to work with multiple working electrodes or a sensor array by means of a multiplexer. The multiplexer switches between the working electrodes in the range of milliseconds.
- each MUX8-R2 multiplexer enables to work with up to eight 2- or 3- electrode systems.
- daisy chaining multiple MUX8-R2 boards (expansion up to 128 channels)
- all hardware settings are controlled by the software making it unnecessary to flick a physical switch
- LEDs to show which channel is selected
- allows to connect auxiliary input (like temperature sensor)
Connection options
The most selected connection option uses two double shielded D-Sub cables ending in 2 mm banana plugs. As alternatives we can provide a PCB with screw terminals, D-Sub cable ending in ferrules or Screen Printed Electrode Adapter. Each of these cables can be connected to 4 channels, if all 8 channels are used, two cables are needed.
