OC2B is an open/closed chassis motor control that has been designed as building block solid state regulated power unit. OC2B uses state of the art control circuitry which can be used by itself, by wiring in the provided speed potentiometer as a straightforward speed regulated control or can be incorporated into much more sophisticated system designs contactor operation, external speed programming and tach feedback etc.

Iso-Volt II

The Polyspede Iso-Volt II circuit board is a signal isolator and conditioner. This board can process a wide range of DC voltage or current signals into an isolated 0-6 VDC output for speed or torque programming of a Polyspede motor control.

The board-mounted ZERO and CAL potentiometers allow precise calibration between the input and output signal levels. The internal or optional external RATIO potentiometer can be set for any lower input-to-output ratio.

The Iso-Volt II is available for 115 VAC or 230 VAC input power applications.

Automation is easy by using the Iso-Volt II as an interface between your Polyspede motor control and your process instruments, line speed tachometers, or other motor controls.

Listed below is related application and ordering information for the Iso-Volt II.
