Computer Conversions Corporation (CCC)

Synchro/Resolver & Motion Control Solutions

Computer Conversions Corporation (CCC) has been an expert manufacturer for over 30 years developing converters, power amplifiers, displays, and encoder solutions for synchro, resolver, and LVDT/RVDT-based position and motion control. Its products are used in a wide range of applications from industrial automation systems to military radar and navigation platforms, particularly where reliable measurement and simulation of absolute angle/position information is required.

CCC offers cards suitable for numerous bus formats such as PC, PCI, PCIe, VME, cPCI/PXI, PC/104, VXS, and XMC, along with synchro/resolver converters, brushless resolver packages, absolute and incremental encoders, programmable limit switches, and angle displays. Thus, it provides a complete product family for carrying shaft/sensor data to digital control systems in both new designs and renovation/improvement projects.

Embedded Synchro/Resolver/LVDT I/O Cards

CCC’s Embedded Synchro–Resolver–LVDT I/O Cards family provides multi-channel AC position sensor interfaces in VME, PCI, PCIe, cPCI/PXI, PC/104, VXS, XMC, and CompactPCI Express form factors.

Up to 4 or 8 synchro/resolver/LVDT/RVDT inputs and outputs can be configured on a single card; card area can be optimized by mixing different converter types.
100% transformer isolation is provided for all AC I/Os, preventing ground loops, inductive pulses, and high-voltage transients from affecting the card and backplane.
Cards are offered in industrial and military (wide temperature range) versions; and easily integrated into PC-based ATE, simulation, and motion control systems with high-speed 32-bit register-based interfaces and a “plug & play” structure suitable for real-time operation.

These cards enable the direct transfer of position and angle data to computer-based control systems in applications such as antenna/target orientation, radar platforms, ship speed indicators, navigation systems, motor/servo feedback, and coordinate control.

Synchro/Resolver/LVDT Converters

In addition to embedded cards, CCC offers independent converter modules:

Synchro-to-Digital and Resolver-to-Digital converters
Digital-to-Synchro and Digital-to-Resolver converters
LVDT/RVDT-to-Digital and Digital-to-LVDT/RVDT converter modules
Custom converters with linear DC, ACP/ARP, incremental, and quadrature encoder outputs

With 10–16 bit programmable resolution, multi-speed (fine/coarse) support, solid-state control transformer/differential transmitters (SCT, SCDX series), and different package options, CCC provides a suitable electronic interface for almost any type of shaft encoder/position transducer.

Power Amplifiers, Displays, and Subsystems/Systems

The product range is not limited to converters.

Synchro power amplifiers and AC reference sources
Angle displays, programmable limit switches, and industrial control modules
Brushless resolver packages, resolver systems, and subsystems
Resolver-based absolute encoder systems and synchro/resolver/LVDT simulators

With these, a complete motion control chain is formed for both real sensors and simulated signals.

Quality and Reliability

CCC offers its products in commercial, industrial, and military temperature ranges; all units subject to static and dynamic tests, and test data is provided to the user as standard. The quality assurance program is compliant with AS9100 and ISO 9002 requirements; compliance with quality requirements in U.S. Navy, aircraft, missile, and nuclear programs has been proven.
