SIRIUS® XHS digital counter inputs
As highlighted earlier, the SIRIUS® XHS data acquisition systems boast Dewesoft's cutting-edge SUPERCOUNTER® technology across all eight counter inputs. The counter inputs can be supported on all SIRIUS® XHS instruments, providing users with enhanced counter/encoder input capability.
Counter is available in two options:
Conveniently located on the back panel of the SIRIUS® XHS instrument, the counter inputs ensure easy accessibility and seamless connection of all sorts of counter and encoder sensors via the LEMO 1B 7-pin female connectors.
The counters boast a timebase of 150 MHz, a maximum bandwidth of 15 MHz, and a 32-bit resolution. Dewesoft SUPERCOUNTER® features advanced input filtering to address glitching issues.
Counters channels can be also configured as digital I/O, supporting in total 24 digital inputs and 8 digital outputs.
Standard Supercounter inputs are compatible with 3.3 V TTL/CMOS logic levels.
The variable trigger option of the Supercounters allows the user to adjust trigger level freely in the range of -2 V to + 50 V. Each counter input channel has one digital input which offers AC coupling. With higher overvoltage protection this option is perfectly suited for applications where digital logic is used on high DC potential.
SIRIUS® XHS counter inputs support all these modes:
Event counting
Waveform timing
Encoder
Tacho
Geartooth
Each counter channel comes with three standard inputs (A, B, Z) necessary for encoder applications. It also provides +12 V and +5 V for sensor supply, along with digital output for alarming and fast triggering.
The counter channels can also be used as a digital output. Digital outputs utilize 5 V push-pull logic with a fast triggering option. The triggers out module enables digital outputs based on custom conditions. Either from the analog input channel or digital input channel. This trigger option operates in real-time on the hardware itself. Users have the flexibility to customize the shape of the output pulse in terms of delay and duration.
The total response time can go below 500 ns, proving beneficial in time-critical applications such as emergency shutdowns or alarms.
