Main features and advantages:
Wide input voltage range: F7126 can accept an input voltage range of 18-36 V DC. This wide range enables it to be used in various industrial environments where there may be fluctuations in the input power supply. For example, in areas with mobile industrial equipment or unstable power grids, the module can still operate at its optimal state, ensuring the continuous operation of the connected security system.
Stable output voltage: It provides a precisely regulated 5V DC output, which is crucial for powering sensitive electronic components in safety related automation systems. The output voltage can be adjusted within a range of ± 0.5 V, with the factory setting at 5.4 V DC ± 0.025 V. This level of accuracy ensures stable power supply to the connected devices, minimizing the risk of faults caused by voltage fluctuations.
High output current capacity: With an output current of 6.3 A (some specifications) or up to 10 A (other specifications), F7126 can power multiple devices simultaneously. This high current capacity is crucial in large-scale industrial applications, where many sensors, actuators, and control units require power supply. It can meet the power requirements of complex security related device networks without any problems.
High efficiency: The efficiency rate of this module is>90% (some sources) or ≥ 77% (other sources). This high efficiency not only reduces power consumption, but also reduces heat generation. In industrial environments where energy conservation is important and excessive heat may cause problems for other components, the efficiency of F7126 is a significant advantage. It helps to reduce overall operating costs and improve the reliability of the entire system.
Safety isolation: There is a safety isolation of>3 kV DC between the input and output voltages. This isolation protects the connected equipment from electrical faults and surges in the input power supply. In industrial environments where electrical noise and voltage spikes are common, this isolation function ensures the integrity and safety of safety related automation systems.
Overvoltage and short circuit protection: The F7126 is equipped with overvoltage protection, set to 6.5 V ± 0.5 V. It also has a short circuit protection function to ensure that the output is protected under short circuit conditions. These protective functions can prevent damage to the module itself and the connected devices, improving the overall reliability and service life of the system.

Application areas:
In the refinery,F7126 supplies power to the complex network of Safety Instrumented Systems (SIS). These systems are responsible for monitoring and controlling key parameters such as pressure, temperature, and flow rate. Once an abnormal situation occurs, such as a sudden increase in pressure that could lead to catastrophic rupture, the SIS powered by F7126 will quickly issue an emergency stop signal to isolate the affected area. The stable power output of this module is crucial here, as any power fluctuations can cause delays in operations that are critical to life and property safety.

In chemical plants, the safety requirements for handling hazardous substances are extremely high, and F7126 supplies power to a series of equipment. This includes designing safety valves to release excess pressure in the reaction vessel, as well as emergency lighting systems that are crucial for safe evacuation in emergency situations. This module is capable of operating within a wide temperature range of -40 to+70 ° C, making it suitable for harsh environments commonly found in chemical manufacturing, where extreme high or low temperatures may exist.
