Constant Current Aversive Stimulator

ENV-410B
Dual Range Constant Current Aversive Stimulation Source

The ENV-410B aversive stimulation module is designed to provide constant current stimulation with continuous regulation at a lower voltage (250 Vrms) than older designs. This eliminates the possibility of tissue damage. Use this unit for direct aversive stimulation output or with the Solid State Grid Floor Scrambler (ENV-412). Output is adjustable in two ranges from 0 to 1 or 0 to 5 mA using a two position range switch and an adjustment knob. The current is shown with a digital display. The resolution of the scale is 0.01 mA. Other features include a dummy load/subject switch, LED indicator, front panel operate, precision digital meter, and optically isolated zero crossover activation. Use with SG-6080C or SG-6010 interface and module cabinets. Remote activation requires 28 V DC. The panel size is double width. Use an SG-216A-10 cable with Molex^® connectors to connect to any 28 V DC output.

ENV-413
Microcontroller Constant Current Aversive Stimulator

This unit extends the program control of the ENV-410B from onset and duration only to include current intensity. The ENV-413 is easily programmed in MedState Notation™. Other programming languages are available. It was designed to operate from MED-PC^® through a DIG-729 controller. Multiple modules can be installed in a single cabinet with solid state scramblers. Use SG-219C-10 control cables to connect each cabinet to the DIG-729 network and shorter SG-219D cables to interconnect modules in the same cabinet.

SG-219C-10
DB-15 Control Cable, 10'

This 10' (3.0 m) cable is required for the first ENV-413 aversive stimulator in each module cabinet. Note, cabinets are limited to four packages each by the power supply.
