The 836-C65 controller is an electromechanical pressure control switch that has been designed and distributed by Allen-Bradley/Rockwell Automation as part of the Bulletin 836 Pressure Controls series. It is a Style C 836 series pressure controller, it has a pressure specification of 65, and it has an open enclosure type. Some of the components of this device include the contact block, clear contact inspection cover, differential pressure reference scale, differential pressure range adjustment screw, operating pressure range adjustment screw, external bellows connection, mounting bracket, and the nameplate with pressure and electrical rating information. The Allen Bradley 836-C65 pressure control device features independently adjustable operating and differential pressure ranges.

The Allen-Bradley 836-C65 electromechanical pressure controller from the Bulletin 836 Pressure Controls series is intended for use in different types of applications and industries. It is designed to be flexible and easy to install, and it can be used in pneumatic pressure systems and hydraulic pressure systems for functions such as maintaining the preset pressure levels between 2 different values. The 836-C65 pressure control unit can be used to operate by detecting overpressures of liquids or gases in pressure systems, thus protecting the machines, personnel, and application processes. Additionally, it is suitable for use in detecting excessively low pressures to protect the host equipment from lubrication loss and coolants loss. The Allen-Bradley 836-C65 electromechanical pressure controller has an operating pressure range of 35 to 375 PSI, a differential pressure range of 8 to 80 PSI, and maximum line pressure and occasional surge pressure ratings of 650 PSI each.
