Description
Dwyer ACT-SR07 is a pneumatic and electric actuator designed for hazardous locations. It has a temperature range of -40 to 140°F and can be powered by 110 VAC, 220 VAC, 24 VAC, or 24 VDC. The enclosure rating is NEMA 7, and it has electrical connections of 1/2″ female NPT. The actuator features powder-coated aluminum construction, a cycle time detailed in the instruction manual, and a maximum supply pressure of 120 psi. It is available in DA (double-acting) or SR (spring return) types, and comes with a position indicator and two limit switches as standard features. The supply pressure for DA models is 40 to 115 psi, and for SR models, it is 80 psi. Other specifications include NAMUR standard accessory mounting, a modulating input of 4 to 20 mA, and a duty rating detailed in the instruction manual.
