Compact Dotmatrix Displays in Snap-in Housing for Easy Mounting


ELECTRONIC ASSEMBLY’s LCD Dotmatrix series in snap-in housings provides text displays in three variants, and four different font sizes with graphics, icons and logos.

ELECTRONIC ASSEMBLY GmBh introduced ready to operate LCD Dotmatrix series in snap-in housings for fast and uncomplicated mounting.


All displays are addressed through the serial RS-232C interface as standard. Optional control through RS-422 is also possible. Data transmission rates of 300, 1,200, 2,400 and 9,600 baud are selectable. All cursor controls, such as line feed, are executed automatically.

Text displays in three variants
The snap-in variants are available for three text displays with 1×8, 2×16 and 4×20 characters, as EA SER081-92NLED, EA SER162-92NLED or EA SER204-92NLED.

They are able to display the complete ASCII code, including German diacritics and “ß”. The installation dimensions (70.5×48.5 mm) and the viewing window (56.5×22.0 mm) are identical for all of them.

  • The single-line version EA SER081-92NLED can display eight characters with a height of 11.48 mm.
  • The two-line model EA SER162-92NLED displays 16 characters each with a height of 6.68 mm on two lines.
  • The four-line panel EA SER204-92NLED consists of four 20 characters with a height of 3.72 mm.

The text displays can be connected directly to a PLC, as they can be powered with 9 to 35 V same as with 5 V.

Current Consumption
The current consumption for all three models amounts to 140 mA.

Up to 64 displays can be individually addressed at a serial interface via adjustable addressing. Optionally, they are also available with a keyboard input for a 5×5 matrix. Its integrated panel lighting can be switched on and off by software command.

Touchscreen Displays For The Raspberry Pi

Four different font sizes in one display

This display can display a maximum of 8×21 characters in four font sizes, also in mixed display. Moreover, it loads small graphics, icons or logos via the RS-232 interface (optionally also RS-422).

This allows displays to be adapted individually and texts and measured values to be highlighted as required. Minimum effort required, to realize situation-adapted display content.

Display’s Viewing Window
The module with 71.6×40 mm still offers generous viewing window, even with compact external dimensions of 93x70x28 mm. Runs on 5 volts and draws a maximum of 220 mA when the LED lighting is activated.
