GENERAL DESCRIPTION Models 290A 292A cost, compact, isolation amplifiers that optimized single multichannel industrial applications, respectively. model 290A self-contained oscillator intended single channel applications. single external synchronizing oscillator drive model 292A's virtually limitless number model 292A's configured using multiple oscillators. user supply external oscillator circuit specify model oscillator module, which includes voltage regulator operation over wide single supply voltage range +28V. Models 290A 292A design features include: adjustable gain, from 100V/V, dual isolated power, ±l3V ±1500V ground isolation, l00dB minimum 60Hz, source imbalance, compact 1.5" 1.5" 0.6" module. Models 290A 292A achieve input noise pk-pk (10Hz bandwidth, 100V/V), nonlinearity ±0.1% pk-pk output, input/output dynamic range pk-pk. Using modulation techniques with reliable transformer isolation, models 290A 292A will interrupt ground loops, leakage paths, voltage transients, while providing 2kHz (-3dB) response. WHERE MODELS 290A 292A Industrial Applications: data acquisition systems, computer interface systems, process signal isolators high instrumentation, models 290A 292A offer complete galvanic isolation protection against damage from transients fault voltages. High level transducer interface capability afforded
with pk-pk input signal range gain 1V/V operation. portable single multichannel designs, single power supply operation (+8V +16V) enables battery operation. DESIGN FEATURES USER BENEFITS Isolated Power: Dual ±l3V output, completely isolated from input power terminals (±1500V isolation), provides capability excite floating signal conditioners, front buffer amplifiers remote transducers such thermistors bridges. Adjustable Gain: Models 290A 292A adjustable gain offers compatibility with wide class input signals. single external resistor enables gain adjustment from 1V/V 100V/V providing flexibility both high level transducer interfacing well level sensor measurement applications. Floating, Guarded Front-End: input stage models 290A 292A directly accept floating differential signals configured high performance instrumentation front-end accept signals having with respect input power common. High Reliability: Models 290A 292A conservatively designed, compact modules, capable reliable operation harsh environments. They have calculated MTBF over 400,000 hours designed meet MIL-STD-202E environmental testing well IEEE Standard Transient Voltage Protection (472-1974: Surge Withstand Capability).
