The 871295-8 application field and working principle can be categorized as Miscellaneous. 871295-8 is an integration module for Emergency Stop System, designed to integrate a variety of emergency alarm functions on the fieldbus. The module provides a common button for connecting three emergency alarm and corresponding signal output signals. During an emergency situation, the button can pull three signal wires up simultaneously and, depending on the system set up, can trigger additional emergency alarm equipment such as truck brakes.

The main features of the 871295-8 module includes direct fieldbus connection with no additional wiring required; local reset button to enable rapid reset for emergency conditions; two local status indicators to provide feedback on signal status and visual detection; adjustable sensitivities for each input signal; and different trigger behaviors for each signal. 871295-8 is a versatile and cost-effective solution for emergency stop applications.

The working principle of 871295-8 simply involves the receiving of input signals from various sources, such as manual or electronic emergency stop switches, alarm horns, buzzers, etc. When any of these input signals are triggered, the module will automatically send out an emergency stop signal to the connected fieldbus. In some cases, 871295-8 also has the ability to trigger additional emergency signals; such as brakes on a truck, or tools to immediately stop operation. For resetting the system, a reset button is provided to quickly resume normal operation.

In addition to emergency stop systems, 871295-8 modules can also be used as part of a safety interlock system. The module provides two signal output lines for the purpose of interlocking with other devices. This feature helps to further reduce the risk of accidental operation during an emergency situation by ensuring that the system will automatically stop the connected devices until the reset button is manually operated.

871295-8 is especially useful in hazardous environment such as industrial sites, mines, and other potentially dangerous work places. In such situation, the emergency stop system acts as a secondary back-up system to quickly activate once any of the input signals are triggered. This fast response time significantly improves the safety of personnel working in hazardous environments.

Therefore, 871295-8 application field and working principle definitely belong to the category of Miscellaneous. By seamlessly integrating emergency stop systems, 871295-8 module provides a simple but highly effective solution to improve safety in hazardous environment. Thanks to its versatility and cost-effectiveness, 871295-8 is a popular choice for emergency stop systems in industrial sites.
