What characterizes milestones in technical development? These milestones make the impossible possible! Complex obstacles are overcome while freedom and flexibility increase. All these characteristics apply to THE BARRIER from Pepperl+Fuchs. This new product represents a big step forward for process automation.
This ground-breaking device replaces several traditional modules with a single multi-functional I/O module. Pepperl+Fuchs is the only company providing flexible isolated barriers corresponding to universal input cards of control systems.
