P-Series ProAct™ Digital Actuators

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 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

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.
