The A103-002 is a low cost positioning or length measurement display when used with a bidirectional encoder or other input device that produces quadrature signals. Housed in a DIN standard 36mm x 72mm case, its features include an input scale factor which allows its display to be calibrated in meaningful engineering units such as inches, feet, yards or meters. It has an 8 digit supertwist LCD display which can be backlighted by connecting an external DC (10-28 Volt) power supply. It is powered by either one or two replaceable 3V Lithium batteries which allows for a new battery to be installed before removing the old one. A NEMA 4X front panel and noise immunity tested to IEC 801 level 3 makes this unit suitable for harsh environments.
