IO505: RS-232/RS-422/RS-485 serial UART protocol support from Simulink

IO505

Galvanically Isolated Serial I/O Module Supporting RS232/RS422/RS485

The IO505 I/O module is a galvanically isolated 4-channel, RS232-, RS422- and RS485-capable asynchronous serial module with Simulink^® driver blocks.

The serial channels offer the highest flexibility as they are individually programmable. The maximum supported baud rate for RS232 is 921.6 kbps and 5.5296 Mbps for RS422/RS485. The termination is software-selectable for RS422 and RS485.

This I/O module is ideal for closed-loop controls and hardware-in-the-loop (HIL) simulations using MATLAB^® and Simulink.

4 channels individually programmable as RS232, RS422 or RS485 (half and full duplex)
RS232 baud rate up to 921.6 kbps
RS422/RS485 baud rate up to 5.5296 Mbps

MTBF (Mean Time Between Failure) - MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2; Environment: GB 20°C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
