Innovation design on reliability、flexibility、expansibility and stretch
The i-8411/i-8811 is equipped with 4/8 I/O slots and multi-serial ports. It not only
supports i-8K and i-87K series I/O modules such as DI, DO, DIO, AI, AO and
Counter/Frequency for I/O slots application, but also the I-7K series I/O modules for a
wide range of RS-485 network application.
Each I/O modules allows various numbers of channels. For example, with i-8040 or
i-8041, the i-8810 provides max 256 digital input or digital output channels.
For more information on i-8K and i-87K series modules, please refer to "Appendix B.
i-8K and i-87K series I/O modules".
Built-in watchdog circuit
The built-in watchdog circuit will reset the CPU module if a failure occurs in either the
hardware or software. If the application program does not refresh the watchdog timer
within 0.8 sec, the watchdog circuit will initiate a reset of the CPU.
