DESCRIPTION •
The SG 2D is a universal digital speed control for combustion engines. The SG 2D is configured via a direct configuration cable (DPC), a PC, and a PC software tool. Configuration of the SG 2D can also be carried out utilizing the push buttons and the four-digit display on the control.
The SG 2D speed control is designed for a wide variety of applications ranging from variable speed mechanical drives to isochronous gensets.

The SG 2D has a configurable start fuel limit level [%] and ramp rate [%/s]. The speed reference can be changed remotely through the analog (0/4 to 20 mA or +/-3 Vdc) speed bias input. This remote speed input allows for isochronous load sharing using external power management products (e.g. Woodward GCP Series). The overspeed protection, maximum fuel limit, and actuator droop may be adjusted in the SG 2D.
