Allen-Bradley 836-A1E Pressure Control Module

Allen-Bradley 836-A1E Pressure Control Module is a general-industrial pressure control switch from Rockwell Automation’s Bulletin 836 family, designed for pneumatic and hydraulic systems that require a reliable trip point. It uses an internal copper alloy bellows sensing element and is housed in a metallic aluminum enclosure rated for multiple NEMA configurations (Type 7 & 9 and Type 4 & 13) within a device-style A package. The unit ships with standard trip and reset settings factory-set within the maximum operating range and minimum differential defined for this pressure control switch. For Style A models like the 836-A1E, the adjustable operating range runs from 30 in Hg vacuum to 375 psi, with an adjustable differential of 2 to 95 psi and a maximum line pressure of 750 psi, with occasional surge pressures up to around 850 psi in some service conditions. This pressure control module is designed to sense process pressure and actuate connected control circuits in industrial equipment such as machine tools and presses, providing dependable mechanical pressure switching in rugged environments.
