Description

Eight input channels
Four-pole relay switching
Selectable buffer for V-sense lines
Rear-panel bypass for unlimited daisy-chaining

The SIM925 is an eight input channel, four-wire multiplexer for low-level signal applications. Kelvin-lead measurements are supported with optional buffering of the two sense leads. The buffer can be switched out to form a simple relay-based, 4-pole/8-throw switch. Multiple modules may be cascaded allowing unlimited networking possibilities.

The digital control circuitry in the SIM925 is designed with a special clock-stopping architecture in which the microcontroller is turned on only when switch settings are being changed. This guarantees that no digital noise contaminates low-level analog signals.
