11.1 SW9001 Multiplexer Module (2-wire/4-wire)
Features
The SW9001 is a multiplexer module that can be attached to the SW1001 or SW1002 Switch
Mainframe.
• 2-wire 22-channel or 4-wire 11-channel multiplexer
• The module reduces electromagnetic induction (eddy current) in AC impedance measurement
and minimizes the influence on measured values by reducing magnetic flux leakage due to
measurement current and separating the source wire from the sense wire.
• It can be connected up to 2 instruments by switching the analog bus.
