IO504: 8 Port Serial I/O Module

8 port serial I/O module supporting RS232, RS422 and RS485, with Simulink driver blocks

This is a very versatile asynchronous serial module supporting RS232, RS422, or RS485 on each of the 8 ports individually. It supports very high baudrates, especially for RS422 and RS485. The Simulink Real-Time driver blockset for this module offers a composite Send/Receive block as well as low-level setup, send, receive, FIFO, status, and utility blocks.

  • 8 independent serial ports
  • Supports RS232, RS422, RS485 half-duplex, and RS485 full-duplex
  • RS232 baud rates up to 921.6kb/s
  • RS422/RS485 baud rates over 5Mb/s

Galvanic isolation is available with the IO505 I/O module.

Reliability  
Mean time between failures (MTBF)* 620,000 hours
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.
