Engineering Advantages
Real-Time Actuator Response
High-speed processing enables near-instantaneous execution of control commands, allowing precise fuel adjustments and stable turbine operation during transient load conditions.
Superior Electrical Isolation
Provides 1000 Vrms isolation between control electronics and field circuits, protecting sensitive components from voltage transients and EMI.
Integrated Fault Detection
Continuously monitors system conditions including overvoltage, undervoltage, and overcurrent events, enabling early fault detection and safe system response.
High-Current Output Capability
Supports up to 16 A output, allowing direct control of heavy-duty industrial actuators without requiring additional amplification hardware.
Programmable Control Flexibility
Configurable control parameters (gain, response curves) allow tuning to specific turbine configurations, simplifying commissioning and optimizing performance.
FAQs
Does it support Woodward TM-series actuators?
Yes. It is compatible with proportional actuators such as TM-series, supporting the required 0–200 mA control signal range.
Can it be used in outdoor cabinets?
Yes, but adequate cooling or ventilation is required to maintain operation within the 55°C temperature limit.
How are faults reported?
The board communicates diagnostic status via the system bus, providing error codes for conditions such as overcurrent or voltage anomalies.
Is this a refurbished unit?
No. All units are 100% brand new, supplied in original Woodward factory-sealed packaging with full documentation and traceability.
