836T-T400J

The 836T-T400J controller is an industrial pressure controller. It is designed by Allen-Bradley and it is part of the Bulletin 836T product line. The trip setting for the pressure controller is the operating pressure setting at which the electrical contacts are required to move. The reset setting is the operating pressure setting at which the contacts return to their normal position. The trip setting is reached when hydraulic or pneumatic pressure is applied to the pressure control actuator, which in the case of the 836T-T400J pressure controller is a piston with a seal. The 836T-T400J pressure controller supports independent trip and reset setting options for differential applications. The 836T-T400J pressure controller  is a Style T pressure controller in a NEMA Type 1, 4, and 13 enclosure.

The pressure specifications for the 836T-T400J pressure controller include a maximum occasional surge pressure rating of 15,000 PSI, an adjustable low reset pressure setting of 0 to 250 PSI, and an adjustable high pressure trip setting of 500 to 3000 PSI. The 836T-T400J pressure controller is a standard pressure controller and it is available from Allen-Bradley with the operating pressure range set to the maximum setting and the differential pressure range set to the minimum setting. A fluid return line for the return of hydraulic fluid to the reservoir is not required for the 836T-T400J pressure controller. The contact block on the pressure controller is an SPDT contact block and it includes 2 circuits. The device style, pressure media, pressure connections, and several other factors need to be considered when ordering a pressure controller from Allen-Bradley. For optimal pressure control performance, an ambient temperature range of -30 to 66 degrees Celsius is required. Only trained technicians should install the pressure controller.
