836-C11A

The 836-C11A controller is an Allen-Bradley Bulletin 836 pressure control device. It is used for the activation of electrical circuits depending upon measured pressure levels. The pressure rating of the 836-C11A controller is 650 PSI. Type C pressure controls with external copper alloy bellows such as the 836-C11A controller can have pressure ratings ranging from 30 to 900 PSI. The Bulletin 836 series also includes 2 other types of pressure controls which are Type A with internal bellows and Type C with external stainless steel bellows. The adjustable pressure range for Type A pressure controls is 30 to 375 PSI and the pressure range for Type C pressure controls with external steel bellows is 30 to 375 PSI. The 3 different types of pressure controls which make up the Bulletin 836 series also have different maximum pressure thresholds.

The adjustable differential pressure (mid-range values) for the 836-C11A controller is 16 PSI. The peak line pressure rating for the 836-C11A controller is 1300 PSI. This controller has a Type 1 enclosure and comes without factory modifications. An LED pilot option is not available on the 836-C11A controller. The control has a standard contact block with a single-pole, double throw snap action. Non-inductive DC ratings for the 836-C11A controller are 57.5 VA at 115 to 230 Volts. The non-inductive AC ratings for the 836-C11A controller are 125 VA at 24 to 600 Volts. The control can be used at temperatures below freezing, provided that the water or other fluids which may solidify and impede the operation of the control are absent. The peak operating temperature for the 836-C11A controller is 66 degrees Celsius.
