Overview

The PCI-SynchroTM  Series" product line are full size  PCI 2.2 compliant synchro, resolver, and LVDT I/O cards, and resolver-sensor card sets are used as absolute encoder systems.

These cards are ideally suited for both industrial and COTS  military  concerns using any PCI bus compatible computer for simulation, ATE, "Absolute" position sensing and motion control, coordinates  & process control, navigation, GPS, data acquisition, radar, ships speed indicators, antenna & targetting applications.

The PCI-SynchroTM Series converters provide up to 4 and 8 channels of Isolated Synchro/Resolver LVDT/RVDT or absolute encoder interface on a single, standard full size 2 PCI printed circuit card.

Computer Conversions' full line of standard, proven "whole" Synchro/Resolver input and output type converters, CT's and CDX's etc ... are used to populate the same standard PCI compliant CCA's.

Differing converters may be mixed to minimize real estate of any type.  Both industrial and COTS military grade (extended) temperature range versions are available.

100% Transformer Isolation is offered for all AC I/O, and various Isolated DC converters are available as standard product, eliminating concerns for ground-loops, ground interjected (intermittent and ghostly) field noise, inductive surges, differing potentials, and high voltage field transients from effecting the card itself, the sensitive PCI bus backplane and any other device or system sharing these signals.

Maximum versatility has been employed on all PCI-SynchroTM products to assure the universal compatibility in adressing, timing, system, and specific computer hardware, software, and backplane independence.   

All PCI-SynchroTM cards are configured with full plug and play capabilities, and are ideally suited to real-time applications because there is no PCI-Bus latency. The interface is a solidly-reliable / high-speed, true 32 bit "Long-Word-Level" register access.

Status registers are provided for various levels of fault indication, Built-in-Test (where applicable), and configuration criteria.

A sample demonstration program written in Visual C++ is provided with source code, which may be easily modified by the user for his/her particular application.

The demonstration program (with source code) is provided for Out-Of-The-Box testing, without any user programming required.

All cards may be user configured completely Bus-Powered, with no external power supplies required. Power souirce jumpers are provided to select the +/- 12vdc power source as "Bus-Powered" or as external inputs via the onboard terminal block.

The use of "proven whole converter" modules assures the user of garunteed systen accuracy and dynamics ability, long term conversion integrity and stability.

All wiring is made through standard or 50 pin "D" style connectors.

Isolated D-A/A-D Converters, Digital Modulators, Demodulators, AC Referencs Supplies, & related function converters may be used with these cards The availability of synchro/resolver I/O on the PCI Bus, allows the user to configure his systems with resident test ability, switched manual or automatic self test, and simulation type programs.

Description

The PCI-SynchroTM cards facilitate up to 8 isolated input chanels, and are 1-8  continuously tracking synchro or resolver to IBM PC/ATTM card converters, employing type 2 ratiometric tracking converters for high performance applications.

They will accept any group of upto 8 individual, or 4 sets of  paired multispeed; 3-wire Synchro, or 4-wire Resolver inputs, or 2-4 wire LVDT/RVDT inputs; over a frequency range of 50Hz. to 10KHZ., and convert them into 10-16 bit words of natural binary data. 

Data is addressable in a long word 32 bit format over the IBM PC/ATTM backplane. Data made available to the bus is continuously updated (tracking) without interruption; output data is accurate, monotonic, and always fresh up to the maximum tracking rate of the converter. 

When the address is applied, and normal bus variables are set; the converters data bits are latched simultaneously into separate buffered registers to prevent false reads.

A Forced Self-test feature is optioned "-WS" that allows on program command an internal disconnect of inputs to read a 30o fixed analog test.

  A continuous Built-In Test (BIT) output representing the tracking mode, Loss of signals, Loss of Reference, for status report are provided for each input channel.

No external transformers, modules or signal conditioners are required.  The synchro/resolver converters used feature internal solid-state or Transformer Isolated Scott T's that accept direct field voltage inputs.

Isolation
Transformer isolated
units are completely isolated from each other and the backplane for all the reference and signal lines.

This completely isolates the card and effectively the whole computer from all field wiring, and especially from any other device sharing these signals: eliminating concerns over; troublesome ground loops, ground induced noise, differing potentials, ground interjected spikes, and  ghostly filed noise that so frequently takes down entire systems.

Bus Powered
No external supplies required ! 
All units are available as completely bus powered via the PCI backplane or as external inputs for the +12VDC supplies. Power required is +12, +3,  and +5VDC, and the source is for the +12VDC is strap selectable for power sourcing via the ISA backplane or as external power via the I/O connector.    

Options currently available include: DC velocity outputs, internal reference supplies, quadrature pulse train outputs, high reliability and mil-grade extended temperature range units.  Units with on-board DC-to-DC converters also available.

Additionally, PC/AT cards can be configured to meet particular OEM requirements.  Many perspective  custom applications can be configured with 100% standard product.

Description
The PCI-SynchroTM output channels are complete PCI to Synchro and Resolver output converters used for self-test, simulation, and control in military and industrial applications.

The PCI card is populated by 1-3 Industry Standard Digital to Synchro and/or Digital to Resolver Converters, CT's or CDX's mixed as specified for the application.

32 Bit long word level double buffered inputs are provided on each channel and addressable via independent or successive address.

The true 32 Bit architecture allows the converters to be written to as single word writes, without any ear of low-byte/high-byte ambiguities.

All of these converters feature virtually indestructibel short-circuit proof outputs, overvoltage, and transient protection, internal solid-plate heat sinks, and automatic thermal cutoff.

Complete transformer isolation is porvided on all reference inputs ad signal outputs to: eliminate ground loops, differing potentials, and to keep any high voltage transients from affecting the PCI backplane.

Both low cost "DSL/DRL Series" and referenced powered "DSP Series" converters are offered to drive on board loads up to 4.5VA and external "booster amplifiers" are available to drive loads up to 150VA.

DSL/DRL TYPE CONVERTERS
The DSL/DRL series are low cost models that are powered from either + 15VDC or optionally +12VDC supplies. The DC supply source may ve field selected as sourced by and external input or Bus Powered for the PC/AT backplane . The power supplies should be verified as capable of providing the required current.

Stadard +12VDC units drive 1.2VA loads, and standard +15VDC units drive 1.5VA loads. Higher drive models are available.

Frequencies of 400Hz. and higher require no external components , and two different types of output transformers are offered for 50-60Hz. units.
These units occupy one full size with a singlewidth slot.

Absolute value, vector units "active" Differentials, Dynamic Rotators, & 2-10HZ. models are available as standards for motor control apparatus and realtime simulators.

DSP TYPE CONVERTERS
DSP series 60Hz. units don't require any external transformers, and drive all 50, 60, & 400 Hz. loads.

The DSP series derives the output power from the reference (RH,RL) input and requires no +15 or +12VDC supplies. This series features a very efficient, internal pulsating power supply that converts the reference input into a high-power, angle-weighted, synchro output format.
400Hz. DSP units drive up to a full 4.5VA load, and 60Hz. units drove a full 1.5VA load direct without requiring external output transformers.
The DSP units occupy one full size doublewidth slot (DSP modules are .8H).

OTHER CONVERTERS
By looking at the model selection guide you will notice the PCI Series models, allow the choice of both Read and Write type Converters. Units with Isolated Digital to Analog, or LVDT converters, multispeed conversion, Vector Generators, Control Transformers, and Differentials etc...can be configured by requesting "IBB Series Extended Model Selection Guide" from the factory.
