Because the AC Reference source is commonly shared or tied to many different destinations (other hardware) in a typical system isolation on the reference inputs protects not only the user circuitry of the D-R converter, but also every user of the reference source in the system.
The use of internal Isolation Transformers on the reference inputs provides phasing flexibility, immunity from ground loops or ground reference induced noise, and are an effective barrier to prevent any electrical noise on the reference source input from effecting the users digital control system and the PC104 databus’ DC supply rails. They accept either direct 115, 26VAC or user scalable inputs as standard model selections. Models are available in both commercial (parts 0 degrees C to +70 degrees C) and extended COTS - Military / Industrial (parts -40 degrees C to +85 degrees C) operating temperature range selections.Īdditionally the PC104-DS Series feature internal micro-transformers for 100% isolation of the AC Reference inputs. Metallic heat sinks are provided to assure high reliability as installed and loaded over the full operating temperature range.īIT inputs and Enable outputs are facilitated for direct compatibility with external Synchro booster amplifiers for driving very high power loads up to 300 VA. These units feature virtually indestructible, thermally and transient protected, completely short-circuit proof, low output impedance amplifiers capable of providing up to a full 50ma.+ output drive per channel. The PC104-DS Series are Low Cost, Dual Channel, PC104 Compliant Digital / Synchro / Resolver Output Cards designed to simulate precision AC Synchro and resolver formatted signals for use in navigation and positioning systems or test sets on both industrial and COTS - military type applications.Īll models provide 16 Bits resolution (0.0055degrees), and model selectable accuracy grades from +/-4 arc.
