KOBOLD Instruments Inc.versal display unit, usable in all 4-20mA transmission circuits, is completely powered via the 4-20mA loop and is fully scalable in any applicable ratio through two control buttons. Programming capabilities include scaling, decimal point location, damping, and optional switch output. Programming information resides inside the system's nonvolatile EEPROM memory, making the unit immune to power failures for up to ten years.
The AUF indication range is -1999 to +9999 with ±0.2% full scale accuracy displayed on an easily readable 4-digit LED. When sandwiched directly between a standard DIN 43650 (Hirschmann style) plug and socket assembly, the unit's compact size makes it the easiest of displays to install. NEMA 4 protection is standard on all units. A typical application would be on 4-20mA pressure transducers to provide a digital display of the current pressure.
