ProAct™ Digital Actuators

    Fast-acting actuators with internal power drivers to precisely position fuel pumps, fuel valves, throttle valves, and wastegates

     

    ProAct P-Series FL Actuator

    ProAct P-Series FL Actuator


    Woodward’s ProAct P-Series FL position controller adds further flexible actuation to the ProAct product line. This new actuator configuration accommodates wiring directly to the unit’s internal circuit board, eliminating the need for an intermediate connector along with its cost. 

    ProAct P-series FL

    The ProAct P-Series FL provides up to 92 lb-in of bi-directional torque through 75° of rotary travel over an operating temperature range of -40 to +85 °C. An internal terminal block accepts the position command signal in the form of PWM, CAN, or analog (jumper-selectable 0 to 5 V dc, 4 to 20 mA, 0 to 200 mA) through gland-nut sealed openings in the external case for an ingress protection of IP56. The position command input can also be set up with a primary and backup input, providing redundancy with automatic failover and backup logic. Input power can range from 18 to 32 Vdc and also enters the case through gland-nut secured access. The P-Series FL actuator also provides a position indication through a 0 to 5 Vdc or 4-20 mA analog output signal along with a relay driver output to indicate an internal fault or error condition.

    P-Series FL actuators come in several output sizes and have the same mounting configuration as the existing ProAct actuators that use a circular connector interface. 

     
    ProAct Digital Plus Actuator

    ProAct Digital Plus Actuator


    The ProAct™ Digital Plus actuator controls varying functions such as fuel rack positioning, timing control, throttle valve, and wastegate positioning, among others. The actuator is effectively a positioner with an integral driver that will accept a position command signal from another device in the system such as a speed control. Its integral digital driver is capable of controlling the actuator, communicating with the outside control system, and containing on-board software and intelligence to realize monitoring and customizing functions.

    The actuators accept PWM or CAN position command signals and can be configured for redundant command signals. The Digital Plus driver is field programmable, allowing a single design to be used in many different applications. 

     
    ProAct ISC Integrated Speed Control

    ProAct ISC Integrated Speed Control


    ProAct™ ISC combines the proven ProAct electric actuator with integrated speed control software to control the speed of diesel and gaseous fuel engines. ProAct ISC is a microprocessor-based speed control incorporated into an actuator, creating a single integrated actuator/speed control. This eliminates the need for an additional driver box and speed control box.

    ProAct ISC can also be configured as a position control only device for basic actuator applications, accepting 4–20 mA, 0–5V, -3V to +3V, or CAN position command signals.

    The ProAct ISC control uses state-of-the-art speed sensing and control algorithms. It also performs comprehensive diagnostics for easy troubleshooting. The ProAct ISC is configured and tuned using the ProAct ISC Service Tool.

    The modular bi-directional actuator design easily attaches to fuel pumps, fuel valves, or throttle bodies.

     
    ProAct ITB Integrated Throttle Body

    ProAct ITB Integrated Throttle Body


    The ProAct™ ITB integrated actuator and throttle body is designed to throttle air or air/fuel for gaseous engines. With bore sizes ranging from 85mm to 180mm, ProAct ITBs are designed for use with engines in the 1 MW to 2 MW range. The electromagnetic actuator has 75 degrees of travel, which alleviates the problems associated with linkages on gas engines (such as setup, non-linearity, and wear).

    This direct combination of throttle and actuator results in excellent stability and transient characteristics, and is designed for direct replacement of traditional throttle valves.
