A/D Boards | DEWE-ORION Cards - 1

DEWE-ORION A/D boards define a new Standard in Data Acquisition! Simultaneous sampling of all analog input channels is guaranteed by using a separate A/D converter for each channel. But more than this all digital I/Os, counters, encoders and the onboard CAN interfaces are acquired synchronized, too. To reach multi-channel instruments several cards can be installed within a single unit. All cards are synchronized via the internal sync-bus to ensure absolute simultaneous sampling of all channels. Key Features Simultaneous sampling Separate A/D converter channel Synchronized analog, digital, counter and CAN inputs Clock output for synchronizing external devices, e.g. video cameras Sync option for synchronizing multiple systems or synchronize to IRIG or GPS For high channel count or distributed systems multiple instruments can be synchronized using the ORION-SYNC option. Depending on distance and local preconditions there are several choices how to use this option. The easiest way is to simply daisy-chain all instruments by sync-cables. Standard CAT6 cables with RJ45 connectors can be used for short distances. The maximum length depends on the sampling rate and the A/D technology and ranges between 30 m to 200 m. For large distances which do not allow physical connection of the instruments a DEWETRON sync-interface using GPS or IRIG time is connected to the ORION-SYNC input. The ingenious driver design enables total continuous gap-free disk storing rates of more than 100 MB/s. Of course each DEWE-ORION card always comes with a calibration certificate. There is no compromise in quality.

A/D Knowledge Analog to Digital Conversion Technologies Delta-Sigma Converter This technique is used in the DEWE-ORION-0424, DEWE-ORION-0824, DEWE-ORION-1624 and DEWE-ORION-1622 /-3222 series boards. The 24 bit converters offer highest dynamic range (up to 120 dB). Whenever you choose a sampling rate, the used internal sampling rate is 512 times higher. Using this oversampling technique full anti aliasing protection is guaranteed. These boards can not be external clocked, but synchronized from board to board and also synchronized to GPS or to IRIG time using DEWE-CLOCK. Flash Converter This...

Counters of DEWE-ORION Boards ADC-clock Counter input DEWETRON distinguishes between two different stages of extension (all of them are fully phase synchronized) ORION standard counters ORION advanced counters In which way are they different? All counter inputs provide felxible signal routing enabling easy signal connection and the usage of the same input pin for all counter input functions and for digital inputs. Some pins even can be used for digital output. In addition to the basic counter functions like simple event counting, up/down counting and gated event counting also period time,...

Counters of DEWE-ORION Boards Counter Options of DEWE-ORION Boards with 2 Counters (-xx0 & -xx1 cards) Without any option the two counters and 8 digital I/Os of the first DEWE-ORION board in a system are wired to a D-Sub-37 socket on DEWETRON instruments. The two counters can be switched to eight digital inputs per software. The figure on the right side shows the pin out of the D-Sub-37 socket labeled “Bx_Digital I/O”. Digital Input Counter Input Counter Digital Input Input As an option (ORION-CNT2LEMO) the two counters can be wired to female 7-pin LEMO sockets in parallel for direct...
