Chassis Mount Resistors: RER50F28R0RCSL Application Field and Working Principle

Resistors are integral parts of electrical and electronic circuits. The RER50F28R0RCSL, manufactured by the Siemens, is a chassis mount resistor. It is a component that retains a fixed level of resistance, and is designed to work in harsh environments where safety and reliability are paramount. This article will explain the application field and working principle of the RER50F28R0RCSL chassis mount resistor.

Application Field

The RER50F28R0RCSL is designed to provide a reliable and durable solution for both commercial and industrial applications. It is suitable for a variety of environments such as, hazardous areas, electrical cabinets, control panels, and more. In particular, the resistor is well-suited for applications requiring resistors of higher power and dissipation, or in areas of high temperature where other components may falter.The RER50F28R0RCSL is designed to be resistant to common environmental hazards, such as extreme temperatures, shock and vibration. As a result, it can be deployed in industrial applications, such as oil refineries and power plants, where safety is paramount. Furthermore, the resistor is designed to be non-flammable and is UL certified for use in UL 508 compliant systems.

Working Principle

The RER50F28R0RCSL chassis mount resistor is a Non-Inductive Fixed Value Resistor. This type of resistor is most typically used in applications where a precise level of current is required for the system to operate correctly. This type of resistor is designed to retain a fixed value of resistance, irrespective of increases in temperature or other environmental conditions. The resistor is composed of two main elements: an encasing and a resistive element. The encasing protects the resistive element and helps it withstand environmental conditions such as temperature and humidity. The resistive element works by providing a fixed amount of resistance to the current it is experiencing. As the current increases, so does the resistive element\'s resistance. The resulting opposition decreases the amount of electrical current that flows through the resistor which protects the connected electrical components from damage due to excessive current.

Conclusion

The RER50F28R0RCSL is a chassis mount resistor designed for industrial and commercial use. It is resistant to environmental conditions and designed to meet UL508 standards. It is a Non-Inductive Fixed Value Resistor, and works by providing a fixed level of resistance that is unaffected by increases in temperature or other environmental conditions. The RER50F28R0RCSL is an ideal choice for use in environments where safety and reliability are crucial.
