849A-ZOB24

Description:

The Allen-Bradley 849A-ZOB24 Pneumatic Timing Relay is a durable industrial automation timer from the 849 series. It receives an electrical pulse that acts as the trigger for changing the electrical status of its internal switch, and instead of performing this change immediately, it waits for a user-configurable timespan before doing so. This relay is suitable for applications in hazardous or even explosive environments.

About 849A-ZOB24

The Allen-Bradley 849 series 849A-ZOB24 Pneumatic Timing Relay is a type of timer switch that is specifically designed for applications where using a straight-up electrical timer instead of a pneumatic timer could be hazardous or even cause an explosion, such as in applications that involve the control and measurement of liquid gasoline levels in a tank. In this pneumatic timer, the electrical contacts are safe for hazardous environments and they are triggered by an external signal which is delayed for a specified period of time that is configured by a simple configuration screw that is located at the front of the unit. The Allen-Bradley 849A-ZOB24 Pneumatic Timing Relay uses a needle valve attached to the configuration screw for regulating the displacement of air from the internal pneumatic bellows until it reaches a point where the electrical contacts are forced to change their default status from open to closed or vice versa.



 



The Allen-Bradley 849A-ZOB24 Pneumatic Timing Relay is normally used in legacy systems and applications and mostly in industries such as chemical processing, oil and gas, and power generation applications. Any industrial application where the surrounding air can accumulate higher concentrations of explosive or flammable materials than normal is an ideal candidate for this pneumatic time relay. The Allen-Bradley 849A-ZOB24 Pneumatic Timing Relay can also be used as a spark suppression or fire and explosion prevention device that contributes significantly to worksite safety. This timing relay is also resistant to high levels of humidity and its accuracy is not compromised by temperature variations. Note that only technicians who have received special training in pneumatics should be allowed to perform maintenance on this timer. Keeping the pneumatic circuit of the timer clean is key for guaranteeing a long, trouble-free operating lifespan.
