Dwyer DDA32 is a Non-Spring Return Direct Coupled Actuator with a temperature range of -22 to 122°F (-30 to 50°C). It has a power requirement of 110 VAC, 24 VAC, ±10%, 50/60 Hz, single phase, with an option for 230 VAC. The enclosure is made of NEMA 2 (IP40) material and has a terminal block for electrical connections. It consumes 5 VA for 110 VAC models, 3 VA for 24 VAC models, and 4 VA for DDC models. The actuator comes with standard accessories including imitative baffles, baffle setscrews, and an aluminum gasket. It is compatible with shaft diameters of 0.4" (10 mm) or 0.5" (13 mm) and has overload protection with a magnetic clutch. The angle of rotation is mechanically adjustable at 95° and the running time varies depending on the model. The actuator features a visual position indicator, clockwise/counterclockwise rotation, and a push button manual override. The control input is two-position floating for DDA and 4-20 mA or 0-10 VDC for DDC. The actuator has a life expectancy of 60000 full cycles and operates quietly, producing sound levels of less than 45 dB.
