Woodward 9907-167 Key parameters

Core Architecture:

Equipped with a 32-bit microprocessor and embedded memory (128 KB RAM, 512 KB Flash) for real-time processing and logic execution in steam turbine control applications.

Input voltage range: 18–32 Vdc, compatible with industrial power systems requiring stable DC supply.

I/O Configuration:

16 digital inputs and outputs for monitoring turbine sensors and triggering safety protocols, paired with 8 analog inputs (0–10 VDC/4–20 mA) and 4 analog outputs for precise actuator control.

Includes 2 actuator outputs (HP/LP valves), 8 relay outputs, and 6 programmable current outputs (4–20 mA) to manage steam valve positioning and system interlocks.

Environmental & Durability:

Operates in -13°C to +65°C (ambient) or up to +55°C with an optional NEMA 4X/IP56 enclosure for dust, moisture, and corrosion resistance.

Compliant with CE, UL, and cUL certifications, ensuring reliability in harsh industrial environments.

Control & Communication:

Integrates Modbus and Ethernet TCP/IP protocols for seamless connectivity with HMIs, SCADA, or plant-wide DCS systems.

Features PID-to-valve ratio auto-calculation and bumpless control mode transfers to minimize process deviations during load changes.
