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.

Decentralised I/O requires suitable field-level connections. For connectors, cordsets, junction boxes and other connection components, explore our TURCK Industrial Connectivity Solutions.

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.

How Does TURCK Remote I/O Work?

TURCK Remote I/O allows I/O modules to be installed closer to field devices while communicating their signals with a central PLC or automation controller through an industrial network.
01. Field Devices Generate Signals

Sensors and switches detect machine or process conditions and generate input signals.

02. TURCK I/O Modules Collect Signals

Connected I/O modules receive digital and analog signals from field devices.

03. Data Is Transferred to the Controller

The I/O system communicates collected signals to the PLC through a supported fieldbus or industrial Ethernet network.

04. The Controller Processes and Sends Commands

The PLC processes the data and sends output signals through the I/O system to control actuators and other field devices.
