The 836T-T252JX40X9 controller is a pressure control and sensing device that has been manufactured by Allen-Bradley/Rockwell Automation. This specific device comes with 2 contacts that enable it to perform a powerful trip action to protect a single piece of equipment or a group of equipment in a system. This pressure controller comes with an enclosure that provides protection against solid particles and can be mounted on a panel or stable mounting surface. It is important to avoid exposing the Allen-Bradley/Rockwell Automation 836T-T252JX40X9 pressure control and sensing device to corrosive materials such as vapor, gases, or liquids. More importantly, the device cannot perform pressure measurements on these kinds of fluids since they may corrode and damage the controller. The internal bellows of the pressure control device are made of copper alloy.

The Allen-Bradley/Rockwell Automation 836T-T252JX40X9 pressure control and sensing device comes with an adjustable operating pressure range and an adjustable differential pressure range. Both ranges can be adjusted to improve the functioning of the trip action and to change the reset setting. When the contacts have performed a trip action, it means the pressure levels have exceeded the established operating range. Once this pressure starts stabilizing, the device will reset and start functioning again. This device has been designed to monitor the pressure of a machine or an application process. The Allen-Bradley/Rockwell Automation 836T-T252JX40X9 pressure control and sensing device comes with a high-intensity pilot light LED that works as an indicator of the current status of the device and its overall operations.
