I/O Modules for Industrial Fieldbus
from trusted manufacturers
I/O Modules for Industrial Fieldbus help you group signals from sensors on a machine and monitor and control the entirety of industrial equipment. They bring invaluable data and connectivity to your machine-building projects, while saving you valuable installation space and cost.
Top-quality products for ultimate control
Our portfolio of extension I/O devices for Industrial Fieldbus includes block I/O Modules as well as fieldbus modular I/O Systems. You can choose from a wide range of products from the renown companies:
Learn about the differences between the two – block I/O modules and modular fieldbus I/O systems
Add, increase, or expand PLC functionality
I/O Modules for Industrial Fieldbus provide you with a wider range of solutions for industrial automation by increasing the functionality of the PLC controller. On a fieldbus system, devices can communicate data between each other and the host control system, using a single pair of wires. With fieldbus, your data is not limited to a measurement variable, but also includes diagnostics data, status information, and alarms.
Apart from much less cabling, the fieldbus I/O is distinguished by smaller cabinet footprint and higher accuracy of the measured variable, as it isn’t converted to a current loop. The possibility of control performed in the field devices lessens the effort of the control system.
Improve process efficiency with fieldbus I/O Modules
Reduce machine manufacturing costs with I/O modules by saving on storage costs, reducing implementation time, and shortening start up times. You will also save due to the uniform connection of devices to the I/O module.
In addition, the I/O modules will allow you to configure your machine at any time. During machine process changes, you will be able to replace devices connected to the module, even while the machine is running. This will make your production line much more flexible.
With the help of the fieldbus I/O modules, you will always know the condition of your machine. They will also provide you with diagnostic information about errors. This will make it easier for you to carry out preventive maintenance and implement appropriate measures in a timely manner.
Fieldbus products resist harsh industrial environments
The use of devices to improve production processes in industrial applications is only possible if all components survive the difficult environment. I.e., they must endure hot, humid, and harsh conditions.
Depending on the requirements of your application, you can choose from a range of fieldbus I/O Modules and Systems from different protection classes:
- Ex fieldbus products for an explosive environment are designed and certified to meet the highest requirements in terms of explosion protection in process automation.
- IP67 fieldbus products that are water- and dust-proof can be mounted directly in the field.
- IP20 fieldbus products that are protected only against solid objects, are intended for Control Cabinet installation.
Benefit from a great variety of options
A variety of available fieldbus I/O system options determines configuration of the fieldbus system. Depending on your needs you can choose between analog and/or digital signals.
To connect your devices to a fieldbus system, several industrial networks and protocols are available. Depending on your requirements and specifications you have the choice between PROFIBUS-DP, PROFIBUS-PA, Foundation fieldbus, DeviceNet, CANopen and Modbus RTU/ASCII. Also the Ethernet protocols PROFINET, Ethernet/IP, Modbus TCP and EtherCAT are available.
You can also choose between a distributed I/O or remote I/O. The former features multiple controllers and a brain or some computing capacity. The latter, however, is at remote place physically located a distance from a control PLC. It doesn’t have a brain or capability of any computing function at all. There is only one controller, or PLC, involved. This type of set up comes in useful when modules are located in hazardous zones.
Use fieldbus technology in various applications
You can use block I/O modules and modular fieldbus I/O systems in a wide range of process automation applications, e.g.:
- Data acquisition for Industry 4.0
- Modular machine building
- Distributed assembly production lines, F&B, intralogistics, etc.
Some of them are designed and certified to meet the highest requirements in terms of availability and explosion protection in process automation, especially in the:
- Pharmaceutical,
- Chemical and
- Oil & Gas industries.
