The Ovation controller can directly support up to 16 independently driven branches of Ovation I/O. For local I/O, all modules reside in up to four standard cabinets, which are placed side by side. All field wiring leads to these cabinets.
Ovation Local I/O Specifications | |
---|---|
Max branches per controller | 16 branches |
Max I/O modules per branch | 8 modules |
Max I/O modules per controller | 128 modules |
Max local I/O bus length | 20m (60ft) |
Redundant Ovation I/O modules are installed in the same fashion as standard Ovation I/O modules, but are associated in pairs located in adjacent branches.
The module pairs exchange health, status and I/O information via their personality module interconnections. This approach allows the user to take advantage of I/O redundancy by wiring the field terminations into a single terminal block on the primary I/O base, with no special control strategy configuration required.
Redundancy is applied at I/O configuration time, and during normal operation, the Ovation system automatically reads and compares the I/O channels of both modules and determines which value to use. When a fault is detected the system automatically switches to the backup module thus increasing reliability and availability of the process inputs or outputs.
Refer to the Ovation Redundant I/O Overview data sheet for complete details.
