Input/output (I/O) relay modules are instrumental components used in electrical control and automation systems to transfer signals from one system to another. A type of I/O relay module is the X4ODC5 manufactured by Gowanda. This device uses solid-state relay technology, with a switching time of 5 ms (max.). In this article, we’ll examine the typical application field and explain the working principle of X4ODC5.

Application Field
The X4ODC5 is designed for use in a variety of general-duty and industrial-grade applications, such as machine control, power control, DC motor control, and so on. It supports both AC and DC control signals, allowing a wide range of applications. The X4ODC5 also provides weather security and offers high immunity to noise, thanks to its internal noise filter. It is also compatible with most PLCs and other industrial controllers, making it ideal for industrial control systems.

Working Principle
At the core of the X4ODC5 is a patented solid-state relay (SSR) technology. Essentially, an SSR operates by turning on and off a solid-state switch to control the current flowing through it. The X4ODC5 includes a state-of-the-art MOSFET circuit, allowing it to switch on and off at very high speeds (up to 5 ms). As such, the X4ODC5 is capable of quickly and accurately controlling the current flow, as required for various industrial applications.

When used with DC power supplies, the X4ODC5 employs an isolated DC-DC converter to provide the necessary voltage. This is typically achieved via an optocoupler, which provides the necessary isolation between the input (e.g., a DC power supply) and the output (e.g., a DC motor). The optocoupler will also form a stable voltage and current loop, allowing for a desired control signal to be transferred from the X4ODC5 to the output.

On the other hand, the X4ODC5 uses an SCR (silicon controlled rectifier) as an AC-controlled switch. An SCR is able to provide a very precise and fast switching action, allowing for precise control of AC power. The SCR’s switching time is significantly faster than mechanical relays, and its immunity to noise is also higher.

In sum, the Gowanda X4ODC5 is a reliable and robust I/O relay module designed for a variety of industrial applications. Its patented solid-state relay technology allows it to provide consistent and reliable control signals, while its internal noise filter ensures a high immunity to noise. In addition, its SCR switching technology and isolated DC-DC converter allow for precise control over DC and AC power sources.
