849A-ZOB24

The Allen Bradley 849A-ZOB24 is a pneumatic timing relay that provides essential timing functions for control applications. It is compatible with a nominal voltage range from 110 to 120 volts AC and operates at frequencies between 50 and 60 Hz. This ensures solid functionality across different electrical environments.

This relay is designed with normally open electrical contacts that handle a rating of 10 Amps at both 120 and 240 volts AC, making it suitable for various circuits. The timing range extends from a mere 0.05 seconds to 180 seconds, accommodating a wide variety of timing needs. Designed for on-delay applications, the timing mechanism can be adjusted using a manual dial or screw, allowing for straightforward and precise timing configuration.

The 849A-ZOB24 includes mechanical isolation to effectively separate the coil from the contacts, enhancing reliability and safety. Constructed with silver alloy contacts, this relay ensures high performance and a lower likelihood of contact failure over time. For installation, it uses a panel-mounted design accompanied by screw terminal connections, simplifying the wiring process.

This device operates reliably in ambient temperatures ranging from −10 °C to +60 °C, making it robust enough for many industrial environments. Additionally, the relay withstands operational shocks of up to 10g without compromising performance. Overall, the 849A-ZOB24 is engineered to deliver dependable timing control in a compact form factor.
