Description

Woodward 9907 Key parameters

Core Design:

Microprocessor-based architecture optimized for single extraction/admission steam turbines, supporting split-stage actuators (1–2) to regulate inlet steam valves.

Field-programmable via a 30-key multifunction keypad and dual-line LED display (24 characters per line), enabling real-time adjustments to control logic and setpoints.

Environmental Resilience:

Operates in temperatures from –20°C to +60°C, with storage tolerance of –40°C to +85°C.

Optional NEMA 4X/IP56 enclosure for protection against dust, water ingress, and corrosive agents, though thermal management may require airflow considerations.

Electrical & Output Configuration:

Input: +24 Vdc at 1 A; outputs include 2 actuator channels, 8 relay outputs, and 6 programmable current outputs (4–20 mA).

Integrated emergency stop and overspeed test buttons for rapid safety interventions.

Communication & Software:

Supports RS-232/422/485 protocols and interfaces with OpView™ and 505View software for system diagnostics and monitoring.
