Resolver to Digital Converters (HSDC/HRDC27 Series) is the digital to synchro converters or resolver to digital converters for continuous tracking of type II servo loop, it parallelly latches and outputs 12-bit or 14-bit natural binary coded data with 32-line dual-in-line metal package, features the advantages of small volume, light weight and high reliability etc., it is widely applied in such automatic control system as Radar system, navigation system, etc. The operating power adopts ±15V and + 5V DC power. There are two types of output signal: three-line synchro and reference signal (SDC converter) or four-line resolver and reference signal (RDC converter); the output adopts parallel digital codes of binary system.

Resolver to Digital Converters (HSDC/HRDC1459 Series) synchro/resolver-digital converter is a hybrid integrated conversion device for continuous tracking designed on the principle of model II servo. This series products are designed and manufactured by MCM process, the core elements adopt special chip developed independently by our institute. The pin arrangement is compatible with SDC14560 series products of American DDC company, 16-bit parallel natural binary code data latch output, 36-line DIP totally sealed metal package, have the advantages of high precision, small volume, low power consumption, light weight and high reliability etc., and can be widely used in important strategic and tactic weapons such as aircraft, naval vessel, cannon, missile, radar, tank, etc.

Resolver to Digital Converters (MSDC/MRDC37 series) are 16-bit digital to synchro or digital to resolver converters. The input signal is divided into four-wire resolver and excitation signal or three-wire synchro and excitation signal. The output signal is parallel natural binary code buffered through three-state latch and compatible with TTL level.
