DATA SHEET
Functional characteristics
Analog processing capability: Supports a wide range of signal inputs from 4-20mA and 0-5V, compatible with various sensors and actuators; equipped with a 4-channel configuration, providing flexible input/output options, suitable for complex control scenarios1.
High precision and stability: Equipped with advanced temperature compensation technology, it can maintain high precision within a wide temperature range of -40°C to +85°C, ensuring stable operation under different environmental conditions; the output signal is proportional to the fuel setting required to achieve the desired speed/load, enabling precise control.
Communication and power supply adaptability: Equipped with an RS-485 Modbus communication interface, facilitating seamless integration with existing control systems for easy setup and configuration; supports a power supply voltage of 12V to 48V DC, adaptable to various power sources.
Durability: Made of high-quality materials, with an IP65 dustproof and waterproof design, it can withstand harsh industrial environments, featuring strong durability, which can reduce maintenance costs and downtime.
Multiple working modes and integration capabilities: There are two working modes: isochronous regulation and droop regulation, which can meet constant speed control (isochronous regulation is suitable for single-machine operation or multi-prime mover collaborative work in an independent power grid) and more flexible control needs (droop regulation); it can work with various Woodward devices (such as automatic power transfer switches, input-output controllers, generator load controllers, etc.) to achieve more comprehensive system control.
Application Fields: It can be used for speed or load control of equipment such as diesel engines, gas engines, steam turbines, and gas turbines. It can ensure that equipment operates stably within the set range in fields such as generator sets, compressors, pump stations, ships, and locomotives.
Relevant Connection Information: Actuator wires are connected to terminals 20 (+) and 21 (-), and the shield is connected to terminal 22; shielded wires must be used when connecting to terminals 28 and 29. In addition, a 100Ω potentiometer can provide ±5% speed adjustment.
