The line includes a segment protector for use with both Foundation Fieldbus and Profibus PA and a Foundation Fieldbus power supply. Based on a T-bus connection system, the components are hot-swappable and allow easy system expansion. The segment protectors serve as an interface between trunk cable and various field devices. The hot-swappable T-bus system makes it easy to expand the system or segment, or to perform maintenance, without disrupting network communication, says the vendor. At just 5.25mm per spur for a 10-spur installation, the modules are designed save significant DIN rail space. Phoenix Contact www.phoenixcon.com800.322.3225
