Industrial and Mechanical Engineering

The comprehensive selection of I/O modules for different potentials and signal types saves time and money because the sensors/actuators can be wired directly – even in safety-related applications.


Building Automation

The broad portfolio enables flexible, cellar-to-ceiling solutions with conventional I/O modules, standardized industry-specific fieldbus protocols and subsystems (DALI, KNX, DMX) for typical applications in lighting, shading, heating, HVAC and more. The whole thing is rounded off by a wide range of accessories (e.g. RJ45 connector or RS485 interface).


Marine and Onshore/Offshore Automation

Use in these applications requires assessment and qualification by independent classification associations such as ABS, GL, LR, etc. More than half of the 20 tests administered apply to EMC. The results achieved from these tests permit operation on marine diesels exposed to vibrations and in the EMC-sensitive area of a vessel’s bridge (compass approval). Of course, these cost-effective modules are also suitable for other industries.


Process Automation

The safety of people, a clean environment and safe, trouble-free plant operation are particularly important to this sector. The possibility of use in hazardous locations is also a requirement in the chemical, energy, gas and oil industries. The WAGO-I/O-SYSTEM is suitable for use in Zone 2 in order to process field signals in Zone 1 and Zone 0 via intrinsically safe I/O modules.


Energy Grids (Telecontrol Technology)

The main objective of the power generation and distribution industry is to ensure the reliable and safe supply of power. With an extensive product portfolio, WAGO offers customers a broad spectrum of application options: the automation of energy generation plants and energy distribution to remote solutions, as well as energy monitoring and control with I/O components for current and energy measurement technology.


Railway Applications

Whether for railway vehicles, signal technology or train stations, WAGO is the right partner wherever electricity flows or signals are transmitted and converted. Our WAGO-I/O-SYSTEM 750 XTR ideally supplements our customer's safety-oriented controls for implementing preventative maintenance. Whether on rails or switches, our products fulfill the requirements of railway standards (DIN EN 50121-4, EN 50121-5 and DIN EN 50155) – no application limitations.
