The Allen-Bradley 836-C11AX15A controller is a pressure control device which belongs to the Bulletin 836 family of electromechanical controls sensors and switches. It is intended for use in industrial applications where the control and monitoring of hydraulic or pneumatic applications is required. Features of the Bulletin 836 sensors include a rugged and compact design, standard and custom controls, multiple enclosure types, copper alloy or steel bellows, an adjustable pressure range, and adjustable differential ranges. The 836-C11AX15A controller is a style C controller with external bellows made of copper alloy. The pressure rating for the 836-C11AX15A controller is 650 PSI. Other specifications include a maximum line pressure rating of 1300 PSI and variable differential rating of 16 PSI. The enclosure type of the control is Type 1.

Factory modifications on the 836-C11AX15A controller include the X15A feature, manual reset contact block, and the single pole double throw feature. The controller includes one normally closed contact that opens on the rise and remains open till the system comes back to normal operation conditions, at which time the contact on the control can be reset manually. A second contact on the 836-C11AX15A controller closes when the first one opens. The 836-C11AX15A controller has default factory settings for resting and tripping. The types of pressure media which can be controlled by the Bulletin 836 controls include air, hydraulic fluids, water, and various types of liquids and gases. The actuator used on the control will vary with the type of pressure media. The 836-C11AX15A controller is not suited for use in hazardous locations. The operating and storage temperature ranges for the 836-C11AX15A controller are -22 to 150 and -22 to 200 degrees Fahrenheit.
