SYNCHRO-TO-DIGITAL CONVERTERS The SDC series converters are continuous tracking, type 2 servo loop, synchro or resolver to digital converters intended for military and industrial control applications. All units feature transformer isolation of the signal and reference inputs with up to 500V dc common mode voltage capability. The SDC1700, SDC1702 and SDC1704 are unique in that transformers for 60Hz are included withir. the low profile height of 0.4. All units provide a BUSY output line which indicates when the output counter is being changed. An INHIBIT input line is provided which prevents updates of the output. Input/outputs are TTL compatible. The SDC1700 and SDC1704 have a velocity output pin which provides a dc volt- age Droportional to input angular velocity. This output can replace a separate tachometer in certain control loop applica- tions. Outputs are provided in parallel in natural binary angle. The MSB equals 180, the next equals 90, etc. SPECIFICATIONS (typical @ +25C and +15V dc and +5V dc unless otherwise noted) Oucput Accuracy Signal Signal Reference Tracking Acceleration Temp Frequency Resolution (See Note) Ref.
