DEWE-ORION-1616-10x
The input voltage range in sensed mode is limited to ±12 V. The voltage level of the sense input is the same
like the current set input voltage range.
Example for input range ±5 V
Ch x = +8 V, Sense = 4 V, voltage difference = 4 V, result is valid
Ch x = +10 V, Sense = 6 V, voltage difference = 4 V, result is not valid (the input voltage is less than
12 V but the sense voltage level (6 V) is higher than the input range.
If you use a customized cable for signal connection, we strongly recommend using twisted pair cables.
Although the single ended configuration each channel has to get its own twisted pair with signal and AGND.
Otherwise the high channel to channel isolation (channel cross Talk) get lost. Also the high signal to noise
ratio can only be guaranteed by using a shielded twisted pair cable to connect the signal sources to the
DEWE-ORION-1616-10x.
The analog input structure of the analog expansion board (DEWE-ORION-3216-10x) is absolute identical to
the structure of the main board.
2.5 Counter and digital I/O
2.5.1 General functionality
The DEWE-ORION-1616-10x is also suited with synchronous 32-bit counters and digital inputs. The flex -
ible signal routing allows easy signal connection and the usage of the same input pin for all counter input
func tions and for digital inputs. Some pins also can be used for digital output. In addition to the basic coun-
ter function like simple event counting, up/down counting and gated event count ing also period time, pulse
width, two-edge separation, frequency and all encoder measurements are sup ported.
2.5.1.1 DEWESoft settings
In Dewesoft there are three basically functions implemented:
Event counting
Waveform timing
Sensor
