BLK202A-S Application Field and Working Principle

The BLK202A-S is a type of display module used in various industrial, marine and commercial applications. This module is intended for use with 12- and 24-volt systems, and features a dual-line, 20-character, dot matrix LCD display. Generally, it is used to indicate the parameters of temperature and other system status. The BLK202A-S display module consists of a liquid crystal display, two control buttons, two LEDs, and two covers (indicators) in one 8mm, 2RU chassis. The module measures 114mm x 60mm and requires a nominal supply voltage of +5VDC. The display module uses a character generator ROM and ROM select/blank control, operated by an industry standard HD44780 chip, to generate the characters that are shown on the LCD screen. It is designed for a 12-character per output RAM interface.The BLK202A-S display module provides the following features:

• A dual-line display of 20 characters each
• Point mode selectable for each RAM character
• Ability to set up or disable CGROM/CGRAM
• A separate LED status indicator for each line
• Ability to customize the backlight brightness
• Built-in EEPROM memory
• RJ45 Connector with two buttons and two LEDs
• An optional energize and acknowledge relay

The module can be used with an optional relay connected to a terminal block or RJ45 port on the back of the display unit. The relay can detect an energize signal and acknowledge a response when receiving data. It can also be used with a terminal block for connection to external data and/or power peripherals.In addition to displaying various parameters, the BLK202A-S display module can also be used to set up alarms and alerts. The alerting feature measures the parameters and if any of the parameters fall out of an acceptable range, it will display an alert message on the LCD screen.The BLK202A-S display module can be used in a variety of applications, including temperature and current monitoring, production line process monitoring, CNC control, temperature monitoring, and process control. It is also suitable for use with other electronics such as HVAC systems, dedicated controllers, magnetic sensors, and many more.The BLK202A-S display module is a user-friendly and reliable industrial display solution. It is easy to install and its operations are straightforward, making it a great choice for industrial and commercial applications. The rugged design makes it ideal for harsh and humid industrial environments, while the long-lasting backlight ensures the display will be visible even in dimly lit areas. The BLK202A-S display module is a cost-competitive solution for any industrial, marine or commercial application. The dual line 20 character display and built-in EEPROM memory provide an efficient and reliable way to monitor and display various parameters. With its robust design and reliable performance, the BLK202A-S display module is an ideal choice for any type of industrial display application.
