XRA1203IL24-F application field and working principle

XRA1203IL24-F application is mainly in industrial automation, remote device control and instrumentation. It is mainly used for digital output and digital sensing and in these applications, signal integrity and interface compatibility is most important. The applications of XRA1203IL24-F include automatic test systems, industrial system development and instrumentation.

Digital I/O Expander

A digital I/O expander is a device which provides additional I/O ports to an existing system. The XRA1203IL24-F is a digital I/O expander which can expand up to 24 digital inputs and outputs. It provides an external relay which can be controlled by digital I/O and can rapidly switch between two states in order to control the external devices remotely. The digital I/O pins can be configured as Input, Output, Interrupt or PWM.

Working Principle

XRA1203IL24-F has 24 digital I/O pins which can be configured as either output or input. The digital output pins provide 3.3V or 5V level output operating at TTL or CMOS voltage levels. The digital input pins can be configured to detect any level between 0V and 5V. The external relay can be controlled by the digital I/O pins. The relay contacts can be switched from ON to OFF or from OFF to ON rapidly with a minimum switching time of 25ms.

Relay Control

XRA1203IL24-F has an external relay that can be controlled by the digital I/O pins. The relay is rated at 3A and 75VAC. It can quickly switch between two states to control external devices, such as motors, pumps, valves, etc.
