LED Indication is one of the most commonly used methods to visually indicate the presence of power and status of a device or environment. Discrete LED indicators are separate, individual LEDs that are placed in different locations to indicate various states in the system. One of the most common examples is the LED indicator for power on/off. The LED indicator for this state usually takes the form of a single red LED which is used to indicate the presence of power in either the powered on or powered off states. A typical example of discrete LED indicator is the SLI-343D8U3F.

Application Field of SLI-343D8U3F

The SLI-343D8U3F is a discrete LED indicator developed by Synapse Technology Corp., specifically designed for industrial and commercial applications. In particular, it is used to visually indicate the presence of power, status, and warning signs in machinery and environments. Some common examples of its applications include; equipment power on/off status indicators, environmental alarms, and fault warning indicators in industrial systems.

Working Principle of SLI-343D8U3F

The SLI-343D8U3F is an LED indicator driven by an integrated circuit that is optimized for robust operation in harsh environments. It has a small form factor that is designed for use with minimal real estate. It operates on DC voltages between 3V and 20V and has a current consumption of less than 8mA. It follows a simple on/off principle which can be triggered by either a low (L) or high (H) signal on the input I/P pin. When triggered by the L signal, the LED indicator will turn on, indicating a presence of power. On the other hand, when a H signal is detected by the I/P pin, the LED indicator will turn off, indicating the absence of power. The indicator can also be triggered manually via a push button switch connected to the I/P pin.

The integrated circuit of the SLI-343D8U3F also contains a Schmitt Trigger - an electronic circuit with hysteresis which increases the noise immunity and switching speeds of the indicator. This, in turn, makes the indicator highly reliable and more able to handle fast changing signals, providing false-positive readings in harsh environments.
