The Allen-Bradley 836-C8S electromechanical pressure controller has been manufactured as part of the Bulletin 836 Pressure Controls product series. It is a Style C controller, it has external copper alloy bellows and Type 4X non-metallic enclosure for protection, but it supports no modifications. This unit has a maximum line pressure rating of 500 PSI and 650 PSI of maximum rated occasional surge pressure. The adjustable differential pressure range of this controller is from 4 to 45 PSI, and the adjustable operating pressure range is from 6 to 250 PSI. Some of the typical applications of the Allen-Bradley 836-C8S pressure controller include compressed air monitoring systems, control of liquid levels, vacuum transfer systems, monitoring low/high pressure, and high pressure alert applications. 

Other notable features of the Allen-Bradley 836-C8S series electromechanical pressure controller include an ambient operating temperature range of -30 to 66 degrees Celsius and an ambient non-operating temperature range of -30 to 93 degrees Celsius. It comes with a non-inductive voltage rating of 240 Volts with a current rating of 5 Amps, and 600 Volts with a current rating of 3 Amps. The Bulletin 836 series pressure controls, including the Allen-Bradley 836-C8S pressure controller, generally come with repeat accuracy ratings of -/+ 0.5 percent and also with independently adjustable differential and operating pressure ranges. Additionally, they are approved and certified for compliance with the CSA and UL standards and with the NEMA requirements. Because the Allen-Bradley 836-C8S pressure controller has copper alloy bellows, it cannot be used in applications that involve corrosive chemicals, vapors, gases, or fluids.
