Eagle Signal manufactures electronic timer, electromechanical timer, and other devices. Within the electromechanical family is the HQ4 series of percentage timers. Percentage timers are a type of repeat cycle device that is compact and long-lasting. The HQ4 series is a unique timer that can function as an on delay, off delay, interval timer or repeat cycle device. Eagle Signal offers this accurate, economical, enclosed timer for a wide range of applications. Specifically, those where repetitive ON times of a fixed cycle requires adjustability. This series is a panel mounted unit with an exposed dial. The load relays’ seal protects against the environment. The HQ4 proves to be durable in industries such as chemical, feeding, irrigation controls, electric heaters, and motor controls. Recently, Eagle Signal developed an improved version of the HQ4 Series called the Cycl-Time® or CT4 Series.
The CT4 offers improved features including resolution, potentiometer, ease of setting, torque, safety, sealings, and wiring. Also, the Cycl-Time®’s resolution is more defined. For example, the colors of the faceplate offer more contrast for reading the time settings. With 100 ticks around the dial rather than 50, the CT4’s percentage options are more precise than the HQ4. The torque of the Cycl-Time® dial is more resistant to change than before. Once the timer is set, it will not rotate any further without intentional force from the user. These features combine to make the timer more accurate and easier to set. Safety is always the greatest concern when designing any product. The Cycl-Time® has a plastic guard over the terminal block to protect the user’s fingers from exposure to contractors. This percentage timer is ideal for applications environmental factors would usually cause concern. These features provide a longer lasting product and additional safety. The wiring and electrical connections of the HQ4 was also updated for the CT4. It now has four electrical connections, rather than seven, all in a straight line on the back of the body of the timer. As mentioned before, this timer is made to panel mounted. Eagle Signal continues to design the most accurate, economical, and reliable products in the industry. The HQ4 and Cycl-Time® Series are both exceptional devices fit for their specific applications. Cycl-Time® proves to be a respectable replacement option to the HQ4 Series.
