The Woodward 8406-121 is a sophisticated microprocessor-based control system. Here is the detailed information:
The Woodward 8406-121 is designed for gas or diesel engine-based generator sets, providing comprehensive automation and protection functions.
It measures 282 x 358 x 69 mm.
It is equipped with two LCDs, which can display operating information, status information, and tuning set points. The backlight remains on when the engine speed is above 50 rpm and turns off after 5 minutes of inactivity when the engine is not running or when the supply voltage drops.
It has over/under alarm and shutdown settings for oil, water, and battery, ensuring the safe operation of the generator set.
The input voltage is 50–150 Vac (PT input), 9–32 Vdc (SELV), with a nominal value of 24V.
The operating temperature range is -20 to +70 °C (-4 to +158 °F), and the humidity can reach 95% at 20 to 55 °C (68 to 131 °F).
The storage temperature range is -40 to +105 °C (-40 to +221 °F).
- Engine Control: It can control the start, stop, and operation of the engine.
- Gen-Set Synchronizing: Capable of controlling the synchronization of the generator set with the system.
- Load Control: It realizes real (kW) load control and reactive (kVAR) control.
- Automatic Generator Sequencing: Supports automatic sequencing of multiple units.
- Communication: It has a PC interface and supports various industrial communication protocols such as Modbus RTU and Modbus TCP, which can be integrated with SCADA or DCS systems.
It is suitable for various applications, including backup power, baseload, peak shaving, and distributed generation systems.
