DS4 Bi-phasic Stimulus Isolator

The DS4 takes an analogue voltage waveform defined within your own data acquisition/ control system and converts it into an isolated constant current stimulus.  The DS4 will accept several input voltage ranges and produces four output ranges (±10µA, ±100µA, ±1mA and ±10mA).  It also features a GATE input, so that several DS4 units can be controlled by a single analogue waveform, but enabled individually via this GATE input.  A timed "inactivity sensor" reduces battery usage and damaging "leak currents" during infrequent stimulation, while at the same time maintaining low levels of zero crossing distortion for repetitive waveforms.  This stimulator is NOT approved for use on human subjects.
