The Murata DVME-613 Isolated Industrial Product Data Channel VME A/D Board is a low-cost isolated analog input board for VME bus computers. The DVME-613 will accept sixteen single-ended or eight differential input channels which are all isolated from the VME bus by ±500 Volts. In addition, each channel is protected from adjacent channel overloads up to ±150 Volts. The common mode voltage range is ±11 Volts relative to isolated analog ground.
The analog input range is selectable as ±10 Volts for bipolar inputs or 0 to +10 Volts unipolar. By using an on-board programmable gain amplifier (PGA), inputs may be accepted directly from bridges, load cells, RTD's, and strain gauges. The PGA includes selectable gain ranges of times one, ten, and on hundred for low level inputs.
An optional signal conditioning pad area accepts shunt resistors, attenuators, hash filters, and clamps. This allows direct input from isolated 1-5 mA or 4-20 mA transmitters and from voltage sources greater than ±10 Volts full scale. For bridge-type sensors, on-board regulated DC excitation voltage is provided which is fully isolated from VME bus.
The DVME-613 inputs are plug compatible with DATEL's DVME-691 rack-mount signal conditioning panel for screw terminal inputs. Three A/D converter options are offered. The DVME-613A is a 12-bit A/D converter with overall accuracy of ±0.05% of full scale. Resolution of the DVME-613A is 2.5 millivolts per count for unipolar inputs.
The DVME-613B offers a 14-bit A/D converter and for highest resolution inputs, a 16-bit converter is included on the DVME-13C. All models produce left-justified data outputs so that boards may be interchanged without having to rewrite existing software to scale the data. A/D conversion takes 24 microseconds for the DVME-613A. The sampling A/D converter design offers continuous automatic calibration. To insure reliability in industrial process control environments, lcoal channels may be dedicated to ground and reference inputs for self-testing of signal paths.
The DVME-613A Murata Isolated Industrial Product Data Channel VME A/D Board may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
