Description

MAGNA Series Clock & Timer Large Digit Displays can serve as accurate time-of-day clocks that are visible across a factory floor. Typical accuracy is within two minutes per year. By using the optional serial data output, a single clock display can feed up to 32 synchronized slave displays around the factory.

MAGNA Series Clock & Timer Large Digit Displays can also serve as highly accurate count-up or count-down timers. A battery-backed quartz crystal clock chip provides excellent long-term stability. Start and stop signals can be proved by common industrial pulse inputs, such as contact closures, NPN or PNP proximity sensors, 5V logic pulses, or 24V PLC pulses.

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. Clock displays are available with 4 or 6 digits for a HH:MM or HH:MM:SS display with colon dividers.

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.

Options include two or four 2A relays, an analog output, an RS232 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.
