8800-1001 | Woodward Two-Channel Digital Engine Speed Switch

Product Description

The Woodward 8800‑1001 DSS-2 is a two-channel digital speed switch designed for precise engine and turbine speed control in diesel, gas, and generator applications. This microprocessor-based device enables accurate load sharing, speed regulation, and process management, ensuring stable operation in both isolated and parallel power systems.

With dual independent channels, the 8800‑1001 supports simultaneous monitoring of multiple inputs, allowing flexible frequency-based control from magnetic pickups. Moreover, its built-in SPDT relay outputs provide reliable switching for alarms, trips, and actuator control. The compact panel-mount design simplifies installation while maintaining rugged performance in industrial environments.

This digital speed switch integrates seamlessly with SCADA, PLC, and EMS systems, thanks to Modbus RTU/TCP and CANbus communication, enabling real-time monitoring and efficient system integration. Its fast response time and high accuracy make it ideal for power generation, marine propulsion, and industrial process control where precision and reliability are critical.
