Dwyer DDC13 is a non-spring return direct coupled actuator suitable for temperatures ranging from -22 to 122°F (-30 to 50°C). It operates on power requirements of 110 VAC, 24 VAC, ±10%, 50/60 Hz, with optional 230 VAC for DDA models, and 24 VAC for DDC models. Enclosed in a NEMA 2 housing, it features a terminal block for electrical connections and consumes low power (DDA: 5 VA, DDC: 4 VA). Standard accessories include imitative baffles, baffle setscrews, actuator body setscrews, and an aluminum gasket. It fits shaft diameters of 0.4" (10 mm) or 0.5" (13 mm), has overload protection with a magnetic clutch, and offers a mechanically adjustable angle of rotation of 95°. Running time varies depending on the torque (72 sec. for torque up to 53 in-lb, 160 sec. for 70 in-lb). It has a visual position indication, allows for both clockwise (CW) and counterclockwise (CCW) rotation, and has a manual override push button. Control input options include two-position floating for DDA models and 4-20 mA or 0-10 VDC for DDC models. The Dwyer DDC13 has a life expectancy of 60000 full cycles and produces sound at <45 dB.
