Interface I/O Expanders, such as PM8054B-F3GI, are complementary devices to IO-limited applications designed for extending a control networks’ I/O capabilities. They are designed to enable the fast and easy integration of multiple IO devices with the highest flexibility.

The PM8054B-F3GI is a Universal Analog/Digital IO expander, based on an 8-bit parallel I/O architecture with up to 3 channels. The PM8054B-F3GI is an integrated solution, offering up to 14 channel modes, including digital level checking and general-purpose I/O (GPIO). Its features include high-speed data transfer (up to 3 Mbps), wide input range (2.5V to 12V), low power consumption (1.5mA max) and a robust design.

To use the PM8054B-F3GI as an I/O expander, it is first necessary to configure the expander through the I/O expander’s dedicated programming mode. In this mode, the user can configure the expander according to their application requirements by setting the I/O channels, input-output type, input range and output logic levels. After configuring the I/O expander, the user can then achieve a higher level of automation and control in their control systems by connecting a large number of IO devices to the PM8054B-F3GI.

For applications where low-cost, high-speed I/O expansion is needed, the PM8054B-F3GI is the perfect choice. The PM8054B-F3GI can be used for industrial, medical, and commercial applications, including access control systems, security systems, automatic data acquisition systems, digital displays, and various industrial and consumer control systems.

The working principle of the PM8054B-F3GI is based on the connection of multiple devices (inputs, outputs and sensors) to an I/O expander through serial interfaces such as USB, UART and SPI, using the pins of the expander. The PM8054B-F3GI then builds a network of devices connected to it. Through the I/O expander programming mode, the user can control the output devices (motors, LEDs, etc.) according to the input devices’ status (temperature sensors, photocells, switches, etc.) by configuring their I/O channels, input-output type, input range, and output logic levels.

In short, the PM8054B-F3GI is an ideal solution for those who need to expand their IO capabilities in a cost-effective, yet reliable way. Its fast data transfer rate and low power consumption makes it suitable for any control network, while its versatility and robust design make it a very reliable device.
