4. TURCK Remote I/O & Decentralised I/O Systems
TURCK Remote I/O places I/O modules closer to field devices instead of routing every individual field signal back to a central control cabinet. The modules collect local signals and communicate with the PLC or controller through an industrial network.
This approach is useful for distributed machines, production lines and process installations where field devices are located across different areas.
Key advantages include:
- Shorter signal wiring between field devices and I/O modules.
- Easier distribution of I/O across machines or production areas.
- Modular expansion of I/O points.
- Reduced need to route individual field signals to a central cabinet.
- Flexible installation for machine-level and field-level automation.

How TURCK I/O Systems Connect the Field to the Controller
The basic architecture is:
Field Devices → TURCK I/O Modules → Fieldbus / Industrial Ethernet → PLC or Controller
For example, sensors can send input signals to a TURCK I/O module. The module communicates this information through a supported network such as PROFINET, PROFIBUS, Modbus TCP or EtherNet/IP, depending on the selected system.
The controller can then process the information and send output commands back through the I/O system to connected actuators and other field devices.
For field devices used to generate these signals, explore our Turck Sensors.

|---|---|
| I/O modules are distributed closer to field devices | I/O modules are concentrated in a central cabinet |
| Suitable for distributed machine architectures | Suitable for centralised control architectures |
| Can reduce individual field signal wiring to the central cabinet | Field signals generally need to be routed towards central I/O |
| Allows I/O to be distributed across different machine areas | Keeps I/O in one primary location |
| Communicates with the controller through an industrial network | Typically connects field signals directly to central I/O |
The choice between centralised and decentralised I/O depends on the overall automation architecture. Explore our TURCK Industrial Automation Products for a broader view of TURCK solutions for industrial applications.
