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

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.

Unique threshold input circuit eliminates damaging

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

¤  Input: Analog input +/-10 Volts. 10 Volt input
    equals full range output.
¤  Output Current-ranges; +/-.05 mA, +/-.1mA,
    +/-.5mA +/-1 mA, +/-5mA and +/-l0mA full
    scale ranges.
¤  Output Voltage ranges; +/-.5 volt, +/-1 volt,
    +/-5 volt, +/-10 volt, +/-50 volt, and +/-100 volt
    full scale ranges.

¤  Linearity- < 1% deviation over entire output range
¤  Rise and Fall times- 8 microseconds, 1mA through 10kW load
¤  Source resistance in voltage mode-10Kilohm, 1% tolerance
¤  External AC power supply for input stages
¤  Isolated output power source- Uses inexpensive readily available
    9-volt transistor batteries (24)
¤  Dimensions- 2.7" high x 7.5" wide x 9.7" deep
