Fieldbus Variable I/O Modules: LioN-Link

LioN-Link is a modular, decentralized IP67 system for field level applications. Based on a bus coupler, the I/O modules are distributed independently of the field bus and decentrally via two lines to the field. Up to 15 modules can be connected per line. A 100 m extension is possible in each case.

Bus couplers are available for PROFINET,  EtherNet/IP, PROFIBUS, DeviceNet™ and CANopen® as well as digital I/O modules in 8 I/O universal or 16 I/O universal or 8 I  

and 16 I variants; there are also analog  input modules as well as valve interface components. The digital input and output modules are equipped with universal I/O functionality, which allows the most varied configurations to be implemented as every signal pin can be used both as an input  

and an output – and without additional  configuration.

The LioN-Link modules were developed for process-oriented use.

Thanks to an innovative technological  development, the complete production  process can be carried out without  encapsulation, making LioN-Link modules ideal for use in the smallest handling robots due to their low weight.

All modules are vibration- and shock-proof  as well as water-proof in accordance with IP67, which means they can be used in a process-oriented applications. The cordsets to the sensors and actuators can therefore also be shortened. Impermeability is guaranteed for a variety of coolants/lubricants. Critical  or unfamiliar agents can be tested in our laboratory for compatibility.

The LioN-Link system offers a cost-optimized wiring solution, due to its field bus-independent  I/O modules. The wiring of the LioN-Link modules is performed on the basis of standard wiring components such as CAN-/DeviceNet™ Thin Cables; no special cables such as fiber optic cables or M12 connectors with special plug-in arrangement (six-pole) are required. A terminating  resistor is not required for connecting the last LioN-Link module in a line.

Use of standardized components allows a reduction in the variety of part types and simplifies global procurement.

LioN-Link provides a comprehensive portfolio of connection components at the field level. These include components for the control of electric drives, the networking of intelligent sensors  and actuators (e.g., proximity switches, motor starters and valves) as well as straightforward retrofitting/conversion of machines.
