A6.1.3 Dataanalog - 8 Channel Analog To Digital Converter; A6.1.3.1 Technical Specifications - Rutter VDR-100G3 Installation Manual

The DataAnalog interface monitors the status of 8 analog input signals, and indicates the voltage
or current on each input channel via an NMEA-0183/IEC 61162 format data sentence transmitted
once per second. Using a 12-bit A/D converter, the interface represents the signal level measured
at the input with a value between -4096 and +4094 in the output data sentence. The DataAnalog
inputs are arranged in four isolated groups of two, which share a common return. This
arrangement provides the ability to simultaneously monitor signals from four separate systems
while maintaining electrical isolation between those systems. It is ideally suited to measure the
electrical indications for order and response from 4 shipboard systems (i.e., Rudder
Order/Response, Engine RPM Order/Response, Pitch Order/Response, Bow Thruster Order and
Response). The internal voltage divider circuit on the inputs can be configured to measure bi-
polar (+/- 5V or +/- 10V), uni-polar (0 to 5V or 0 to 10V), and current (4 to 20 mA) indicators. The
RS232/422 output baud rate is also configurable. In addition to the 8-channel DataAnalog
interface described above, a 4-channel version is also available.
The DataAnalog is certified by the Canadian Standards Association as meeting the rigorous EMC
and environmental resistance criteria defined by IEC 60945. The inputs are high impedance,
output ports are opto-isolated, and the power input is DC/DC isolated. This will ensure the safe,
reliable operation of the DataAnalog and all devices connected to it. It is easily installed and will
provide dependable, uninterrupted service in the extreme environments typically found aboard
vessels.
Features include:
Output channel activity LED indicators;
Power LED indicator;
Configurable input voltage ranges, and output baud rates;
Configurable NMEA-0183/IEC 61162 sentence identifiers (up to 64 unique
IDs);
19" inch rack or DIN rail mountable (mounting brackets available);
Max wire size for smaller gauge Phoenix plug connectors, used on interface front panel
connectors, is 20 AWG or 0.5 sq. mm. Max wire size for the larger Phoenix connectors,
used on interface rear panel connectors, is 18 AWG or 0.75 sq mm;
Power and data output connectors on both front and back panels.
