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.
