SA2
RS422/RS485 Interface Adapter
Hauptmerkmale
- 1 RS422/485 channel
- Optically isolated
- Shielded 9-pin D-Sub connector
Full- or half-duplex communication
The SA2 is a 1-channel RS422/485 half-/full-duplex interface adapter with optical isolation.
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.
