18-28VAC/DC-3/15# EP Xdcr W/OR

The EP-311/313 incorporate quiet low wattage poppet valves and a pressure sensor to measure and adjust the branch line pressure proportional to the input. This unit has no air consumption and is immune to mounting orientation or supply line pressure fluctuations. The EP-313 incorporates a manual override switch and, in the manual mode, the pressure can be increased or decreased with two push button switches. This feature is most desirable for check out/commissioning and manual operation in case of controller failure. Universal 24 VAC/24 VDC supply voltage and field selectable 4-20 mA, 0-5 VDC, or 0-10 VDC inputs ensures single unit compatibility to most of the systems. Unique steel chassis design substantially reduces the overall size of the unit and, at the same time, provides for ease of installation in a control panel directly or with a snap track. A precision gauge is provided for the branch line pressure. Rugged aluminum manifold, brass barb fittings, floating poppet solenoid valves, silicon pressure sensor, high performance electronics and a liberal five year warranty are some of the features which make the EP-311/313 the highest performance and the most reliable electropneumatic transducers in the industry.
