Features of the Stimulus Isolator

This constant current stimulater is activated by conventional logic-level commands. The A365 Stimulus Isolator can be gated by any pulse generator, stimulator or computer output.

Dual Tone Audible Alarms

A tone sounds when an open electrode circuit is detected or when system compliance is reached. A second optional alert tone sounds when a signal is applied to the input. A test switch is also provided to check the battery charge on the stimulus isolator.

Current Delivery

Stimulus currents are set using a three-digit control knob and a three-position range switch. Output current tracks control set­tings to better than 1%. The output current of the A365 direct current stimulator is load independent. The voltage sufficient to push the desired current through the load is automatically developed. It is subject only to compliance limits. The A365 Stimulus Isolator produces up to 10mA current, in three ranges, at more than 100V compliance.


Output polarity is determined by a push switch on the front panel.

Bipolar Pulsing

Bipolar current is toggled by the command waveform, setting alternating pulses as positive or negative.


This A365RC Stimulus Isolator includes both the A365R Stimulus Isolator and the A362 battery charger.The rechargeable A365R is supplied with a nickel metal hydride battery stack. The A362 Battery Charger is required with the A365R
