Overview:

The KOBOLD AUF compact local electronic display transforms any 4-20 mA transmitter into a complete monitoring solution through its innovative sandwich-style design that installs effortlessly between existing EN 175301-803 Form A connectors without requiring additional wiring or power supplies. This intelligent display unit draws its power directly from the current loop while providing a clear 4-digit red LED readout with programmable scaling, decimal point positioning, and adjustable gate time—all configured through simple two-button menu navigation that stores settings permanently in non-volatile EEPROM memory. Available in multiple configurations including standard 2-wire operation, 3-wire compatibility, and optional open collector output for limit switching applications, the AUF accommodates diverse process monitoring requirements across flow, pressure, level, and temperature measurements with exceptional 0.2% accuracy. The rugged orange plastic housing with IP65 protection withstands industrial environments from 32°F to 140°F while the rotatable display orientation adapts to any installation angle for optimal viewing accessibility. With integrated diagnostic monitoring, overrange/underrange indication, and up to 10-year data retention capability, this maintenance-free display upgrade delivers professional-grade local indication without the complexity or cost of traditional panel-mounted instruments, making it ideal for retrofitting existing transmitters or enhancing new installations with immediate visual feedback.
