Seven connection-friendly digital module types
Bachmann introduces intelligent I/O interfaces for the M100 system.
Bachmann's M100 I/O system offers seven different types of digital I/O modules. This means that the M100 system can optimally meet the most diverse requirements for digital signal transmission.
Visually, a 2D-QR code on the display panel is noted at first glance. The 2D-QR code can be scanned with any commercially available smartphone or tablet or with industrial scanners. Device designation, part number, and serial number are immediately displayed. Then a webLink to an extensive information system enables one-click access to data sheet, wiring diagram, user manual or other information concerning the module.
The module types with single-core connection offer a maximum channel density of up to 24 channels per I/O slot. Sensor-specific cables can be directly connected on the modules with a two-core or three-core connection. This eliminates shunting, reduces wiring costs, and facilitates troubleshooting and maintenance.
Each I/O module has a highly accurate and synchronized clock that makes it possible to place the sampling time of the inputs and the consistent setting of multiple outputs, precisely and with optimal spacing relative to the fieldbus cycle. Fieldbus-sync sampling cycles to 100 µs and optional oversampling are possible.
Time stamps to 10 ns resolution enable precise differential time measurement and assessment of event sequences. For precise feed-forward controls or pre-triggers, the M100 outputs can also be switched at a defined point in time apart from the fieldbus cycle. Thus, a more exact process control and higher cycle times are possible, even at slower bus cycles.
All digital input modules have up to four counter units; this means that cost-intensive special counters or position-sensor modules are no longer needed for straight-forward counting tasks. Moreover, external contactors can be dispensed with for many applications in the lower power range: The PWM-capable digital outputs can be switched in parallel multiple times and this enabels multiplication of the switchable load currents.
