Ethernet I/O Modules: Integrating the Field Level into the Network

Seamless connection of sensors and actuators to the industrial network

Ethernet I/O Modules from Pepperl+Fuchs are critical components for integrating discrete and analog signals from the field level directly into the industrial Ethernet network. They act as gateways that standardize communication between various devices (sensors, valves, drives) and controllers (PLCs), utilizing high-speed industrial protocols such as PROFINET, EtherNet/IP, and Modbus TCP.

Purpose and Advantages

These modules provide flexibility, speed, and cost savings in building automation systems:

• Decentralized Architecture: Allows placement of I/O points as close as possible to the equipment, reducing wiring length and simplifying installation.

• Protocol Versatility: Models support multiple protocols, allowing easy integration into any existing network (Multiprotocol I/O).

• High Channel Density: Compact modules accommodate a large number of I/O ports, optimizing space in the control cabinet or directly on the equipment.

• Reliability in Harsh Environments: IP67/IP69K rated models are available for mounting outside the control cabinet, resistant to water, dust, and vibration.

Key Functions of Ethernet I/O Modules

The Pepperl+Fuchs range includes modules optimized for different signal types:

• Digital I/O Modules:

  • Designed for processing binary signals (ON/OFF) from standard sensors, limit switches, and buttons.

  • Often include diagnostic functions and short-circuit protection.

• Analog I/O Modules:

  • Convert standardized analog signals (0-10 V, 4-20 mA) from measuring devices into digital data for the PLC.

  • Provide high accuracy and digitization speed.

• IO-Link Master Modules:

  • Act as master devices that collect data from intelligent IO-Link sensors and devices, connecting them to the Ethernet network.

  • This allows not only transferring production data but also retrieving diagnostic information and remotely configuring sensors.

• Modules for Hazardous Areas:

  • Specialized solutions for operating in explosive atmospheres (Ex-zones), ensuring intrinsically safe connection.
