Control Relays - ControlAir

Control relays are electrical devices that control and switch electrical circuits in industrial automation and control systems. These relays act as electromechanical switches, allowing a low-power control signal to control a higher-power circuit. Control relays are commonly used to control motors, solenoids, lights, and other electrical loads. They provide reliable and efficient control by isolating the control circuit from the higher-voltage or higher-current circuits. Control relays are available in various configurations, such as electromechanical and solid-state relays, offering different features and capabilities. They play a crucial role in automating processes, ensuring proper sequencing, and enhancing the safety and reliability of control systems.

The Type 6000 Volume Booster is a one-to-one signal to output relay that, when used with a positioner/actuator, is designed to increase the stroking speed of control valves. A large input signal change to the volume booster delivers high volume, fast action throttling control. An integral bypass valve provides system stability while allowing normal positioner airflow and normal valve actuation with small input changes. If the volume booster is to be used for on/off control valves, the bypass valve can be closed to optimize stroking speed. The Type 6000 is available in aluminum or 316 stainless steel construction.

The Type 6100 aluminum volume booster is a 1:1 signal to output relays that is utilized in applications that require high forward airflow and exhaust capacities. Typically they are used to increase the throttling speed of large volume valve actuators. They are suitable for either diaphragm or piston actuators. A fixed deadband and adjustable bypass valve combine to allow small incremental downstream adjustment without opening the main booster valve. The bypass valve is used to adjust dynamic response to provide stable operation over a wide range of actuator sizes. Negative Bias adjustment (up to -4 psi) is available to “zero” downstream pressures when using standard signal pressure ranges.

The Type 650 positive bias relay is a signal operated regulator that provides an output pressure that is the sum of the input signal pressure plus a preset bias. The unit allows flow capaci ties up to 50 SCFM with minimal pressure drop. An aspirator tube at the output maintains the set pressure under varying flow conditions by causing the main supp!y valve to open and close proportionally to the flow demand. There is a choice of four adjustment ranges for the positive bias settings. This unit is most often used for conversion of a low flow control signal to the higher flow requirements of an operating system.
