IO-Link master overview
IO-Link masters are the heart of every IO-Link-based automation solution. They connect IO-Link-enabled sensors and actuators directly to the control level, enabling consistent, digital communication down to the field level.
In addition to pure process data transmission, IO-Link masters offer numerous additional functions such as automatic device detection, parameterisation, and comprehensive diagnostics – both locally and remotely.
Intelligent interface between sensors and PLC
Thanks to support for common fieldbus and IT protocols, IO-Link masters can be seamlessly integrated into existing PLC systems and simultaneously used for Industry 4.0 applications – for example, for condition monitoring, predictive maintenance, or cloud connectivity.
We offer the right IO-Link master for your application and requirements.
For classic automation with the PLC
If you want to record sensors or control simple actuators directly via the PLC, our two product lines will help you find the right solution.
The StandardLine (AL11 series) is ideal for all classic automation tasks where simple sensor technology is paramount. If you're after good value and your application has basic performance or functionality requirements, this is the right choice.
- Optimised for simple applications – you only get the features you really need.
- IP67 for industrial applications and IP69K for cleaning processes
- 4 x A ports and 8 x A ports for IO-Link
- Variants for EtherNet/IP and PROFINET
- Basic diagnostic functions
- Ideal for cost-optimised applications
- Ready for moneo configure
The PerformanceLine (AL14 series) is suitable if your system also needs to supply actuators with higher power requirements. This provides more power and flexibility per port without sacrificing simplicity.
- Up to 2A per IO-Link port – enables direct operation of valves, grippers, or small motors without additional hardware.
- Integrated voltage transfer – reduced wiring effort saves space in the control cabinet or field.
- IP67 for industrial applications and IP69K for cleaning processes
- 4 x A ports and 4 x B ports for IO-Link
- Variants for EtherNet/IP and PROFINET
- M12 L-coded power connector with daisy-chain function for voltage transmission up to 16 A
- Ready for moneo (basic)
For PLC and digitalisation (Y-Path)
If you want to not only control your machine but also make it transparent for cloud connectivity, condition monitoring, or predictive maintenance, then our IIoT-capable masters offer the right basis.
The DataLine (AL13 series) is ideal for taking your first steps toward IIoT. It enables access to machine data via both the PLC and modern IT interfaces such as MQTT or JSON.
- Quickly get started with IIoT projects – without changing your existing PLC logic.
- Interfaces such as MQTT/JSON facilitate connection to existing IT systems, dashboards, or condition monitoring solutions.
- IP67 for industrial applications and IP69K for cleaning processes
- 4 x A ports or 8 x A ports for IO-Link
- Variants for EtherNet/IP, PROFINET, EtherCAT, and Modbus TCP
- M12 A-coded power connector
- Ready for moneo (advanced)
The SolutionBlock (AL15 series) combines an IO-Link master and edge device in a single device and enables easy connection to IT systems via integrated Node-RED, MQTT, and OPC UA.
- Complete solution with all IT/OT interfaces – no additional modules required.
- Integrated Linux platform – offers maximum flexibility for future IoT applications.
- Multi-protocol capability: Supports PROFINET and EtherNet/IP
- Certificate-based encryption and OPC UA – meets typical requirements of end customers and IT departments.
- MQTT and REST API in JSON format with TLS encryption
- IODD interpreter: Automatic sensor data translation into plain text
- NTP support: Precise time synchronisation in the network
- Ready for moneo (advanced)
The CabinetLine (AL19 series) offers the same functionality as the DataLine, but is designed for installation in control cabinets. It's ideal for retrofit projects or control centers.
- Space-saving IP20 alternative for control cabinets – without compromising functionality.
- Perfect for centralised architectures, e.g., in building automation or existing machine parks.
- 8x A ports for IO-Link
- MQTT/JSON IIoT port
- Variants for EtherNet/IP, PROFINET, EtherCAT, and Modbus TCP
- Combicon terminals for easy wiring
- Ready for moneo (advanced)
