S/D or R/D Converter, ISA Bus

Description:

The SDC-36016 is a versatile, full-size 8-bit ISA card which can be configured for one to four channels of fully independent synchro-to-digital or resolver-to-digital conversions. For each channel, the conversion process is implemented using a DDC RDC-19222(S) 16-bit Monolithic converter.

Each converter channel can be configured for a 90V or 11.8V line-to-line differential, synchro or resolver format, or 2V single-ended input. Each channel can be programmed for 10-, 12-, 14-, or 16-bit resolution, and 100 Hz, 300 Hz, or a user-defined bandwidth.

Custom line-to-line voltages are also available. Consult the factory for information regarding this feature. Each channel provides a separate reference input signal which can be programmed to accept two voltage ranges. Also, DDC has designed the product to operate over a frequency range of 360 Hz to 5 kHz. Lower carrier frequency operation can be achieved with userdefined bandwidth.

In addition to the angular position data available, each channel provides a ±4V Velocity Signal, which is accurate to 1% of the rotational rate.

Software available on request includes drivers in “C,” Pascal, LabWindows, LabWindows/CVI, and demonstration software, which exhibits the SDC- 36016’s capabilities.
