LED Indication - Discrete refers to the use of LEDs (light emitting diodes) as an indicator in discrete form, as opposed to in continuous form like pixels in an LCD display, for example. The intention is to provide a visual indication for states such as “on” and “off”, “operating” and “standby”, or to signal a change in the system’s operating status.

EAST3215BA4 is an AC/DC output type red LED display indicator module from EAST, designed to indicate on/off functions in application systems. The indicator can be programmed to operate as a signal lamp in systems of an indicator is required. The being rating is UL 94V-0, this module can be suitable in application fields required strong flame retarding performance.

The EAST3215BA4 is a dual-color LED indicator integrated with low current consumption, high brightness and low heat radiation. Outstanding features of the EAST3215BA4 indicator include a standard working temperature range of -40 ° C to +85 ° C, and a working current of no more than 40mA.

In terms of its physical characteristics, the EAST3215BA4 module has low profile with a maximum height of 7mm, and a standardized LED size with a diameter of 5.4 mm. It is simple to install, with two pins for output connection; the pin size is 4.3*0.8mm(L*W), providing excellent connection reliability and stability. Environmental-friendly materials used enable it to pass the UL94V-0 safety test.

In terms of its internal structure, the EAST3215BA4 is driven by TTL logic, and is provided with reverse polarity protection and transient voltage protection. Of the two LED output pins, one is the positive pin, while the other is the inverted pin. The working voltage can be set to 3-5V DC through a power-on/off switch.

The EAST3215BA4 is designed to change color with a programmable supply voltage level. Both of its pins provide output voltage when the voltage of the output pin and the reversed pin are above the set value. Of the two pins, one emits red light and the other emits orange light when the voltage is above 3.6V. When the voltage falls below the set value, the output pin shows a low voltage level, no light emitted.

This module can be used in a wide array of application fields, from systems like security alarm, equipment electric system, to lighting control and automation equipment. The EAST3215BA4 is designed to provide an excellent level of reliability and performance due to its features, and is commonly used to provide a visual indication or as a warning light. As a result, it is widely used in GPS air and ocean navigation systems, as well as in high speed railway signalling systems.
