Description for Barksdale UAS3 Electronic Trip Amplifier
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 1/2Inch 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. For applications requiring precision control, multiple switchpoints, and extremely long life, the UAS3 Series is the ideal solution.General Specifications*Accuracy:0.2% f. s.Linearity Error:±0.2% f. s. at 77°F (25°C)Repeatability:±0.01% f. s.Material:Housing (Electronics):Seal (Housing):Keypad:Cast aluminumNeopreneRPolyester fi lmMeasuring Ranges:(free scalable): -9999 to +9999Measuring Principle:Amplifier with 12 Bit A/D-converterElectrical Connection:Plug-in, terminal strip with 14 slots for 1.5mm2 , 14 AWG slotsSensor Connection:Plug 3-pin acc. to DIN 43650 / meter including electrical plug with molded cableCable Gland:1 x PG 13.5 side entry - standardPower Supply:18 - 30 VDC, reversed polarity protectedPower Consumption:appr. 350 mA at Ub = 24 VDC (without load)A/D-Converter:Resolution:Scanning Rate:12 bit (4096 steps per measuring span)1000 / sAnalog Inputs:Current Input:Voltage Input:Resistance Input:Temperature:4 - 20 mA0 - 10 VDC0.5 - 100 kOhmPT100 element acc. to IEC751Analog Output:Current Output:Load:Load Influence:Scanning Rate:Voltage Output:Rating:Adjustment Range:4-20 mAMax.
