As part of its System 200V range, Vipa, the German designer and manufacturer of modular automation products, offers an alternative range of lower-cost fieldbus and I/O expansion modules. Known as the ECOnomical range, these modules have been engineered to provide mid-range specifications as are often required for smaller and more straightforward centralised automation applications.
The ECOnomical range includes Profibus-DP and CANopen slave modules, each with potential for eight expansion modules. For I/O expansion, the range covers eight- and 16-channel digital input and output units, and four-channel/12-bit analogue input and output units with both +/- 10V and 4-20mA configurations.
Cost savings of up to 50 per cent can be achieved when comparing these modules with full-featured System 200V alternatives, and all modules can be freely mixed to optimise costs in more complex systems.
The compact and modular Vipa System 200V control system has programming options for Siemens Step7, an extensive range of expansion modules and includes a wide choice of master and slave fieldbus options. It is a well-matched and scaleable PLC range, aimed at small to medium, centralised or decentralised automation applications.
