LCD-Terminals
PER LCD-TERM20
- High power nonstandard version of LCDTERM
- Use LCDTERM20 instead of standard LCDTERM for:
4x20 displays. - Large displays requiring high backlight drive current.
- Large or extended temperature modules
requiring high negative contrast voltages. - Non-RS232 levels
- 4 x 20 LCD module driver software and form factor: 60x98 mm.
- Software for other modules available optionally.
900mA @ 5V backlight supply, switchable. - Contrast voltage generation -15 to +5V (for large modules).
- RS232 standard serial line, optional module socket for level shifter modules: 20mA TTY, RS422, fiber optic.
- Other features like LCDTERM
LCDTERM20 is the choice for all applications requiring extra features. Displays with 4 lines of 20 characters are very common but have other character positions than the other displays. LCDTERM20 fits these displays in size and mounting holes.
There are many other applications where special features are needed: extended temperature displays (-10 to +60 °C) often need -5V to +5V contrast voltage while large displays need up to -15V. Also large 12mm character size 4x20 modules need up to 800mA of backlight current where LCD-TERM20 is the choice.
RS232 is very common, however, for extended lengths of cable 20mA or RS422 are better suited. There's an LCDTERM20 version with a module socket that seats level shifter modules for these line types. CTS handshake is not supported on these modules. See LCDTERM for standard features.
Technical data:
Size: 60x98mm, Current consumption with 24V input 15mA, with direct 5V input 55mA. Connectors needed: D9F, 16p header LCD, 20p header keyboard.
