Discrete LED indicator components serve to alert personnel when a switch is in the on/off status, whereby they provide visual and highly reliable feedback as to the status of numerous types of machines or systems. Among them, the SLI-343UR3F device is a specialty discrete LED indicator component that is useful in a variety of applications.

Description

The SLI-343UR3F is a small-sized, discreet component, measuring just 28 mm x 11 mm x 5.8 mm. It features a pair of light sources, associated with an actuation and reset switches, each of which flashes a distinctive pair of green and red LEDs when actuated. This indicator is suitable for a variety of applications, most often in communication and signage systems. It is fitted with flush mounting pins that can be easily adjusted to a variety of mounting positions, making it well-suited for cramped or restricted areas.

Principle of Operation

The SLI-343UR3F is activated when the actuation switch is placed in the on position. This causes an interior microcontroller to energize the pair of green and red LEDs. An increase or decrease in voltage on the reset switch allows the operator to selectively reset the indicator device. In most cases, the reset switch is wired to the control logic to allow reset when changes in the machine’s status trigger a reset event.

Applications

Since the SLI-343UR3F produces both a green and red LED, it is well-suited for signaling binary status information. This type of discrete LED indicator can be used for diverse applications, including machine control systems, instrument panels, and communication devices. For instance, the indicator is often used to signal the presence of fault conditions in an instrument or machine, or to signal the overload or over-temperature in AC power supply systems. It can also be useful in signaling when to replace batteries or cartridges during machine maintenance operations.

It is also useful in operational communications systems, acting as an audible indicator when a data packet has been received from the central unit. The distinctive flash of the green and red LEDs is detectable from a distance, making it easier for operators to distinguish multiple indications of a machine process.

Conclusion

The SLI-343UR3F discrete LED indicator is a highly reliable and accurate signal device for a range of applications. Its distinctive green and red LEDs signal binary information in both visible and audible form, ensuring a high degree of accuracy in determining machine status from a distance. The indicator is small and easy to mount, even in confined spaces, making it an excellent choice for control systems, instrument panels, and communication devices.
