Two sensors - one line Two signals, one line The patented 2:1 technology from Pepperl+Fuchs provides potential savings of 50% on sensor wiring in hazardous areas. Signals from NAMUR sensors can be transmitted in pairs to a control device via one line. Two digital sensors are wired anti-parallel to one strand pair that is connected to the switch amplifier. This device divides the signal again into two separate output channels and sends them to the output. The advantages A significant reduction in material, planning and installation costs for routing cables in hazardous areas A perfect application for system enhancements, when additional signals are to be routed via existing and possibly at-capacity field wiring A special synergy effect is created in combination with Pepperl+Fuchs’ double sensors for monitoring valve or rotary drive positions Pepperl+Fuchs also provides this technology in sensor and valve interface modules for fieldbus applications. End customers such as plant…
