The MSI-9008 Multiplexer is an accessory to the MSI-9000 CellScale. Functioning as an 8 "in" and 1 "out" channel switch, the MSI-9008 expands a single CellScale input into 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 and allows the MSI-9008 to be used far from the CellScale without signal degradation due to background noise. In addition, the MSI-9008 provides switching of the excitation voltage. This reduces power consumption by removing power from any channel/scale not currently being addressed, and also expands the load cell driving ability of the CellScale by a factor of four (excitation is switched pairs). Each channel/scale input is EMI filtered and transient protected. An 8 segment sunlight visible bar graph provides channel/scale status.

Terminals are provided to permit daisy-chaining of a second MSI-9008 module to allow access to more CellScale input channels. Using the maximum number of four MSI-9008 modules permits the CellScale to read 32 independent channel/scale inputs.
