The Allen-Bradley 836-C12J Electromechanical Pressure Controller is an external sensor device from the Allen-Bradley Bulletin 836 Pressure Controls product series. The 836 Pressure Controls devices are designed to monitor or control the operating conditions of both hydraulic and pneumatic-type applications. The 836-C12J Pressure Controller has a compact design and it comes with high-quality components that provide long-lasting operation in applications that involve air, water, oil, vapors, non-corrosive gases, and corrosive liquids and gases. These high-quality components are also notable for their ruggedness and longevity when they are used with all of these substances, thereby improving application processes and systems, protecting expensive equipment, and helping safeguard the operators.

The 836-C12J Pressure Controller is a Style C pressure controller with external copper alloy bellows and adjustable differential and operating pressure ranges. The 836-C12J Pressure Controller features standard quarter-inch NPT female pipe connectors with adjustable pressure trips and reset settings to accommodate a wide variety of applications. The 836-C12J Pressure Controller offers an adjustable differential range from 25 PSI to 115 PSI and an adjustable operation range from 200 Vacuum Mercury (in-Hg) to 900 PSI. It comes with a single-pole, snap-action precision terminal that is equipped with silver contacts. Each contact has a non-inductive current rating of 5 Amps at 240 Volts AC and it can be wired to open or close on increasing or decreasing pressures. The 836-C12J Pressure Controller has 24 to 600 Volts AC and 125 Volt-Amps (VA) or 115 to 230 Volts DC and 57.5 Volt-Amps (VA) control circuit ratings. The 836-C12J comes in a NEMA Type 4 and 13 weather-tight enclosure that provides a degree of protection against water, oil, and non-corrosive liquids.
