Laurel Electronics MAGNA User Manual

ELECTRONICS, INC.

Description

Viewing distances up to 320 feet (100 m) are

achieved with oversize digits. A rule of thumb is that
viewing distance in feet is 40 times digit height in
inches, or in metric terms, that viewing distance in
meters is digit height in millimeters divided by 2.

Four digit heights are available: 57 mm (2-1/4"),
102 mm (4.0"), 150 mm (5.9"), and 200 mm (7.9").
Solid segments are used for normal brightness 2.2"
and 4.0" digits. Individual 5 mm LED pixels are used
for larger digits and outdoor brightness versions.
The number of digits can be 4, 6 or 8, depending on
the display function.

Indoor or Outdoor Viewing: MAGNA Series
Displays with normal brightness LEDs can be read
across an entire plant floor to keep workers informed
without leaving their work area. Displays with
outdoor brightness LEDs can be read across an
industrial yard, parking lot or roadway, for example
to display vehicle load. Available mounting options
are panel mount, wall mount and suspension mount.
Environmental sealing to IP65 (NEMA-4X) is
standard.

Choice of Signal Inputs: MAGNA Series Displays

are available for different signal types, with can each
be associated with 4 or 6 digits. Please click on the
links below for detailed information by signal type:

•

Serial data from PCs, PLCs, serial output
transmitters, and smart sensors.

•

Process input (e.g., 4-20 mA)

•

Strain gauge / load cell input

•

Pulse input for frequency or rate

•

Pulse input for total or quadrature position

•

Pulse input for operation as a clock or timer

Available Options are dual 5A relays, an analog
output, an RS-232 or RS485 serial data output, and
95-264 Vac or 11-30 Vdc power.

Intuitive Setup is normally provided by means of
built-in front panel switches, which can be locked. It
is also possible to remotely wire four pushbuttons to
the display.

Notes: Models with 57 mm (2.2") digits, 4 digits and 4 relays require the larger 6-digit case.

For panel mount versions, add 18 mm (0.7") to case width and height for the bezel and
25 mm (1.0") for cable glands in back of the case.
