A optional potentiometer can provide a resistance (0-135ohm, 0-1Kohm, 0-5kohm, 0-10kohm) signal proportional to the actuators position. The potentiometer can give continuous feedback to control panels and other closed loop devices.

The E-Series actuator can be configured to have three distinct positions. The three position controls is useful in filling applications and multiported valves.

When using the optional two wire control, the E-series (2) position electric actuator can be controlled with a low voltage signal. When the voltage is present the spring loaded relay will trip energizing the actuator to rotate clockwise or counter-clockwise. When the voltage is removed the spring will untrip the relay, energizing the actuator to rotate in the opposite direction.

The Triac DC modulating card (4-20mA input) can be used with the Triac E-Series DC powered actuators. Dynamic braking reduces motor coasting and provides improved control. Low standby current (22mA typical) when the actuator is not in operation.

The Triac Speed Control is a compact module that extends the operating time of the E-Series AC powered actuator by pulsing the motor on and off. Extending the cycle time of an actuator can avoid problems associated with water hammer and control system instabilities.

Control boxes are available for a variety of local control options, such as local/remote open-off-close and jogging control. NEMA 4 housings are used as standard, but other housings are available upon request.
