MSI-9008 Multiplexer

Download Detailed Brochure

The MSI-9008 is an accessory to the MSI-9000 CellScale. It functions as an 8 in and 1 out channel switch. The MSI-9008 expands a single CellScale input to 8 independent inputs. Due to the truly independent calibration capability of the CellScale, scales can be mixed in any type, capacity and resolution.


The MSI-9008 uses new generation analog switches which have a resistance of less than 5 ohm. This allows the MSI-9008 to be used at a distance from the CellScale without signal degradation due to noise pickup. In addition, the MSI-9008 provides switching of the excitation voltage. This reduces power consumption by removing power from any channel not currently being addressed. This also expands the load cell driving ability of the CellScale by a factor of four (excitation is switched in pairs). An 8-segment sunlight visible bar graph provides channel status.


Terminals are provided to permit daisy-chaining of a second MSI-9008 module to allow access to more CellScale input channels. The CellScale has 2 or 4 input channels. Using the maximum number of four MSI-9008 modules permits the CellScale to read 32 independent scale inputs.  Each input is EMI filtered and transient protected.
