Converters require no external transformers.

Press Release Summary:



PC104 Series consists of 3- and 4-channel PC/104 and compatible Synchro, Resolver, and LVDT/RVDT to digital converters employing type 2 ratiometric tracking converters. They accept any group of up to 4 individual, 3-wire Synchro, or 4-wire Resolver inputs, or 2-4 wire LVDT/RVDT inputs; over frequency range of 50 Hz to 10 kHz, and convert them into 10-16 bit words of natural binary data representing input signals absolute physical position.



Original Press Release:


New PC/104 Stackable Synchro/Resolver/LVDT Tracking Input Modules


The PC104 Series are 3 and 4 channel PC/104 and compatible Synchro, Resolver, and LVDT/RVDT to digital converters, employing type 2 ratiometric tracking converters specifically
suited for high performance embedded applications.

They will accept any group of up to 4 individual, 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 virtually jitter and lag free, natural binary data representing the input signals absolute physical position.

Data is addressable in a single word 16 bit format over the PC/104 stack-bus. 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.

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

Transformer Isolation is offered for all the reference and signal input lines. This completely isolates the card and effectively the whole computer from all field wiring, eliminating concerns over: troublesome ground loops, ground induced noise, differing potentials, ground interjected spikes, and ghostly field noise that so frequently takes down, and/or corrupts the operation of entire systems.

Transformer isolated units, facilitate PC/104 module densities up to 4 channels per card, and separate reference inputs are provided for each channel; allowing up to 4 different reference
sources to be used with a single card, and complete channel to channel and channel to bus isolation exceeding 500VDC.

Accuracy, performance, and dynamic characteristics are specified and tested inclusive of the whole PC/104 assembly, and printed test data is provided, and maintained, on all units.

Maximum versatility has been employed on the PC/104 Series' products to assure the universal compatibility in addressing, timing, system and specific computer hardware and software
independence.

The PC/104 Series cards are configured with a full 16 bit range of jumper-plug selectable I/O addressing. The interface is a solidly-reliable, high speed, true 16 bit "Word-Level" register
access. Simply address the I/O; and read the data.

"Auto-handshaking" is provided on board, to prevent false reads, and a true 16 bit data bus is used; there is no need to employ and additional software steps to inhibit the converters, or
manipulating 8 bit bytes; and the user is assured only the most current, valid and "dynamic" data is presented to the bus.

Additionally, a single Status Word is provided to report the BIT/Fault status of each independent channel.

Software code fragments that may be used as drivers, are provided in various and generic C, assembly, and (examples in) Basic programming languages. In additional, a C written
demonstration program is provided for Out-Of-The-Box testing, scaling and offsetting; without any user programming required.

PC/104's are available in: commercial 0°C, to +70°C, industrial -40°C to +85°C (operating), temperature range models. Military extended temperature range units available on request.

These compact, full function highly reliable, low power PC/104 Series converters are ideally suited to applications that demand: assured out-of-the-box performance, finite, data integrity, inherent sensor compensation, long term repeatability and reliability.

Prices start at $995.00 each in small quantities. Delivery is 4 weeks ARO
