The SC40-19SRWA is a type of Display Modules - LED Character and Numeric specifically designed for use in applications involving interfacing TTL signals and controlling data displays. It is a direct drive unit, comprised of an array of 19 digits each of 7-segment type with a total display area of 140 x 19 mm. It can be used both in single and multiple digit combinations.

One of the most advantageous features of the SC40-19SRWA is its compatibility with TTL logic. This is because of the self-contained display power module, which allows connection via logic levels and not current. This makes the SC40-19SRWA adaptable to a range of interface signals, depending on the system’s current requirements.

The SC40-19SRWA is a multi-functional device featuring an array of characteristics that make it particularly beneficial for systems requiring displays of multiple characters. These include extremely low power consumption, register control and indicators, as well as buffer loss protection, making the SC40-19SRWA well-suited for use in a variety of applications. It is also extremely durable, able to withstand environmental exposure and intensive use.

In terms of its working principle, the SC40-19SRWA works by emitting light from the LED segments to form characters that can be read from a distance. The LED segments are driven by a simple logic circuit, with each of the 19 halves being individually controlled. Data is received and stored in a display RAM and written to the LED display in three sequence steps.

The first step consists of writing a character to the LED segments located in the top half of the display module. This is achieved by using RAM to supply the necessary information. In the second and third steps, the data is written to the bottom part of the display and the LEDs lit. On completion of these steps the display will remain on until a new character is received.

The SC40-19SRWA is an energy-efficient device, with a maximum power consumption of 1.4 watts in driving mode and 0.8 watts in standby. The display also offers a range of additional features such as pulse output for optical excellence and auto power save for enhanced power efficiency.

In short, the SC40-19SRWA is a multipurpose display module designed to drive both single and multiple character displays with ease. It offers compatibility with TTL logic, low power consumption, durable construction and additional features, making it an ideal choice for use in a wide range of application fields.
