The 836T-T253JX121X15 controller is an Allen-Bradley 836 series pressure controller. It is available in an oil tight industrial enclosure which is a NEMA Type 1, 4, and 13 enclosure. This enclosure is designed for applications where a stream or water or oil may flow over the enclosure occasionally. Other applications suitable for the 836T-T253JX121X15 controller are those where it is required that the enclosure is able to resist lint, dirt, and dust. A 2-circuit device such as the 836T-T253JX121X15 controller has a single set of one normally open contact and one normally closed contact. The 836T-T253JX121X15 controller is designed for mounting to a base with 2 screws. It should only be supported by the pressure and electrical connections. Allen-Bradley recommends use of a support wrench for tightening the pressure and electrical hub connections.

The 836T-T253JX121X15 controller has bellows which are made from copper alloy. The operating pressure range on the 836T-T253JX121X15 controller is adjustable between 12 and 150 PSI. The differential range on the 836T-T253JX121X15 controller is also adjustable between 6 and 30 PSI. The 836T-T253JX130X15 controller is designed for connection to pressure media which has a maximum pressure rating of 350 PSI. The 836T-T253JX130X15 controller can be connected to pressure media which experiences an occasional surge of pressure at up to 450 PSI. The 836T-T253JX130X15 controller is shipped from the factory with the settings configured for maximum operating rating and minimum differential rating. Standards with which the 836T-T253JX130X15 controller complies include the UL 508, UL 698, CSA 22.2, and NEMA ICS standards. The maximum operating temperature that the 836T-T253JX130X15 controller can tolerate is 66 degrees Celsius.
