BSI-950

Biphasic Stimulus Isolator (Dagan)
Beschreibung

The BSI-950 was designed as a full function, biphasic, affordable, analog input analog output stimulus isolation unit for use externally generated analog stimulation signals. The AC powered input stages are photo isolated from the battery-powered output stage. This device is capable of producing biphasic current and voltage stimulation.

Can be used with Computer Analog Output channel on Computer-based Stimulators

Unique threshold input circuit eliminates damaging leakage currents

Analog input signal must exceed ± 15 mV for output current. This eliminates damaging leakage currents caused by small offsets on data acquisition system.
