Description for Barksdale UDS3 Multiple Output Electronic Switch
Barksdale's UDS3 Electronic Pressure Switch offers the unique ability to switch four discrete circuits in a single, compact unit. In addition to its four SPDT relays, the UDS3 comes tandard with either a 4-20 mA or a 0-10 VDC analog output and a digital pressure display with 1/2Inch tall, easy-to-read digits. A scalable bar graph display provides even greater visibility. Analog 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. Pressure units may be readily toggled between psi, bar, kPa, °C and °F units. For applications requiring precision pressure control, multiple switchpoints and extremely long life, the UDS3 Series is the ideal solution.General Specifications*Accuracy:0.5% FSLinearity Error:±0.5% f. s. at 77°F (25°C)Repeatability:±0.1% f. s.Sensor Element:Piezoresistive silicon measuring cellWetted Parts:Housing:Seals:Keypad:304 stainless steelCast aluminum FKMPolyester fi lmMeasuring Ranges:0 - 9,000 psi, gaugeMeasuring Ranges (psi):1507501500300060009000Proof Pressure (psi):220110021754400900011600Process Connection:1/4“ NPT FOption : G1/4 F, bottom entryElectrical Connection:Plug-in, terminal strip with 14 slots for 1.5 mm2, 14 AWG slotsPower Supply:18 - 32 VDC, reversed polarity protectedA/D-Converter:Resolution:Scanning Rate:12 bit (4096 steps per span)1000 / sTime Constant:Approx. 40sAnalog Output:Current Output:Load:Load Influence:Scanning Rate:Voltage Output:Rating:Adjustment Range4-20 mAmax.
