The Allen-Bradley 836-C12E Pressure Controller Unit is an electromechanical pressure control device from the Bulletin 836 pressure control series that is designed to control and monitor the operating pressure conditions of a wide range of industrial pneumatic or hydraulic applications such as compressed air monitor systems, vacuum transfer systems, liquid level control, and air compressor applications. The 836-C12E Pressure Controller features a rugged, compact, and industry-grade design that helps to improve application processes and systems, to protect expensive equipment, and to help safeguard factory personnel. The Allen-Bradley Bulletin 836 pressure controls feature snap-action precision contacts that provide accurate and consistent operation, and they also feature adjustable trip and reset pressure settings.

The 836-C12E Pressure Controller belongs to the Style C series. The Style C pressure controls feature external Copper Alloy bellows and quarter-inch N.P.T. female pipe connectors for precise and reliable pressure connections. They also offer independently adjustable operating and differential pressure ranges to accommodate a wide range of applications. The 836-C12E Pressure Controller has an adjustable operating range between 200 millimeters of mercury (mmHg) and 900 PSI. It also has an adjustable differential range between 25 PSI and 115 PSI. The 836-C12E Pressure Controller has a maximum line pressure rating of 1300 PSI and an average “occasional surge pressure” rating of 1600 PSI. The 836-C12E Pressure Controller with its copper alloy bellows is compatible for use with water, air, and other liquids or gases that are not corrosive to copper alloy. The 836-C12E Pressure Controller has a single-pole design with standard double-throw contacts. Each contact has a non-inductive rating of 3 Amps at 600 Volts AC and a control circuit rating of 24 to 600 Volts AC (125 Volt-Amps).
