Emerson Ovation™ I/O Input/Output Modules features

Ovation I/O Architecture 

The Base

Ovation packaging reduces the system footprint by using base units which attach to mounting plates by DIN rail;

these hold four independent Ovation I/O modules of any style.

This approach simplifies maintenance by making it easy to install, move or replace individual base units. 

Base unit features include:  

▪ Field terminal blocks that accept two 14 AWG or a single 12 AWG 

▪ I/O bus communications built into the base 

▪ I/O modules automatically addressed by location 

▪ I/O modules may reside in any location 

▪ I/O module redundant power distribution 

▪ No interconnecting cables for I/O bases 

▪ Built-in spare fuse holders and strip gauge in base 

The base unit’s high-impact plastic housing protects the backplane, exposing only the connectors as modules are removed.  

The I/O Module 

The I/O module includes an electronic module and a personality module or cavity insert.

The I/O module converts field signals into data and sends it to the controller.

Electronic module styles include digital and analog input and output modules,

contact inputs, RTD inputs, pulse accumulator / counter, HART input and output modules,

FOUNDATION Fieldbus, Profibus, DeviceNet, Ethernet and serial link controller modules. 

I/O modules offer a number of protective features including: 

▪ Signal conditioning, part of the surge-withstand feature, dissipates voltage “spikes” to protect the electronics 

▪ Fuses protect the circuit in case of a short in the field device line 

Each module is “hot swappable,” allowing it to be removed and replaced without interrupting system power or using mechanical tools.

The standard Ovation system configuration allows for up to 128 I/O modules in a local configuration.

This modular approach simplifies maintenance by requiring less assembly and offering a compact and uniform architecture. 

Controller I/O Capabilities

The Ovation controller supports multiple I/O capabilities in various combinations, including: 

▪ Hardware I/O interfaces to Ovation I/O 

▪ Q-Line I/O plus software I/O in the form of simulated I/O 

▪ Virtual I/O generally communicated from OEM models and systems 

Ovation I/O has two methods of implementation: locally within the controller and remotely away from the controller.

Remote I/O provides a means to distribute I/O throughout a plant.
