I/O Relay Module Racks are used to store and protect various types of I/O (Input/ Output) relays, which are used in power-controlled devices in a wide variety of industrial and other applications. The PB-4H I/O Module Rack is designed with respect to static electricity prevention, heat dissipation, and EMI (electromagnetic interference) prevention, and it offers output selection flexibility and installation components. It is suitable for use in a number of different types of applications where I/O relays are required.

The design of the PB-4H I/O Module Rack uses sophisticated solid-state components in combination with LEDs for better safety. The PM-4H rack has 4 slots for input and output modules, plus 4 slots for output expansion modules. These slots allow for a range of different signals to be relayed, including pulse, ON/OFF, and step-by-step, as well as various combination signals.

The PB-4H is designed to provide a flexible and economical answer to I/O relay requirements. It helps simplify system wiring and make it possible for the user to save power and time when installing, using, and maintaining the rack. The PB-4H also helps minimize any risks related to EMI, providing strong shielding from electrical interference.

The PB-4H has two power ratings: 24 VDC and 12 VAC. The 24 VDC power should be used for general applications, while the 12 VAC version should be used when special protection is needed from noises. The PB-4H also helps protect devices from abnormalities and power-related issues, both during and after installation.

The working principle of the PB-4H I/O Module Rack is based on electrical signals being switched from one segment to another, ultimately leading to the activation or deactivation of the desired output. A circuitry inside the module receives the input signal and relays it to the output segment, where it is amplified. The output is then passed on to a separate output, which is either an electric current or a mechanical movement, depending on the type of application.

In summary, the PB-4H I/O Module Rack is an ideal choice for applications where a range of I/O relays are required. It offers high reliability and strong shielding from electrical interference, making it perfect for industrial and other similar settings. Its two different power ratings also enable the user to choose the best option for their application, and the user-friendly design makes installation, use, and maintenance easy.
