SA24M
IBIS Master
Main Features
- 1 channel master
- Over-current and short-cut protection
- Optical isolation
- -40 °C to +85 °C
Integrated Board Information System
The SA24M provides one IBIS master interface with an external 24 V supply. While a fieldbus master controls the data traffic, the data transfer between master and slave participants is initiated only by the master.
IBIS is a fieldbus used in public transport vehicles. It is based on a UART structure and can therefore be combined with duagon products that support any kind of UART interfaces together with SA-Adapter slots.
Versatile I/O Features
SA-Adapters are small universal boards providing the line drivers for legacy serial I/O, fieldbus interfaces and other I/O functions. One serial line is provided per adapter, which can be plugged directly to duagon products such as CPU boards as a mezzanine. Alternatively, the adapter can be connected to the front panel via ribbon cable.
Interface Extensibility
The SA concept allows to add additional I/O interfaces to duagon products, enhancing flexibility for line transceivers and isolation requirements. Compatibility of SA-Adapters or a combination thereof with duagon products is determined by mechanical, performance, FPGA and operating system criteria and needs to be verified for every board configuration requested.
Long-Term Availability
Long-term availability ensures an extended product life and future-safety.
