Barksdale Electronic Trip Amplifier, UAS3 Series

UAS3 Series Electronic Trip Amplifier

Brand: Barksdale
Add Product to My Catalog

Barksdale's UAS3 Electronic Trip Amplifier and controller is the perfect companion to any sensing device that provides a 4-20 mA or 0-10 Vdc Analog output.

Our UAS3 offers the unique ability to switch four discrete circuits in a single, compact unit. In addition to its four SPDT relays, the UAS3 comes standard with either a 4-20 mA or a 0-10 Vdc Analog output and a digital display with 1/2" tall, easy-to-read digits.

A scalable bar graph display provides even greater visibility. Analog transducer outputs are scalable from 25% to 100% of the full adjustable range.

A 12-bit microprocessor provides built-in diagnostics and allows for switch time delays and pressure cycling up to 100 times per second. Display units may be readily toggled between psi, bar, kPa, °C and °F units.
