WOODWARD DSS-2 Digital Speed Switch (P/N 8800-1001)

Versatile speed monitoring or equipment protection device

Woodward’s DSS-2 combines the convenience of manual adjustments with the flexibility of a computer-based calibration tool. The two-channel electronic speed switch executes a variety of speed-related functions, including starter motor disable and engine overspeed protection. DSS-2 monitors engine rpm via a magnetic pickup (MPU) input and controls two independent relays. Once engine speed exceeds the user-selected speed setpoint, the relay will go to the designated set condition.

DSS-2 has two multi-turn potentiometers for manual speed setpoint adjustment. A computer interface is provided for additional adjustments with the All-purpose Calibration Tool (ACT). For most applications, DSS-2 can be connected and adjusted with simple hand tools. For more advanced features, the calibration tool provides user-friendly access. Three indicator lamps permit system monitoring and diagnosis without use of additional tools.

The unit is fully potted for harsh environments and comes with Euro-style connectors for easy installation. The DSS-2’s universal input accommodates both 12-volt and 24-volt systems. And, it is reverse-polarity protected to prevent damage in case of incorrect wiring.
