Surge voltage protection for analog, digital signals in slim design

July 20, 2010  EP&T Magazine

PHOENIX CONTACT LINETRAB surge protection devices provide surge protection for systems and plants and help prevent costly downtimes. The narrow surge arrestors protect your (0)4 to 20mA analog or 24Vdc digital signals, providing up to 4 channels in a single module. Normal mode surge protection between the signal wires can be extended to almost any degree across multiple modules using a bus adapter for mounting rails. This can provide effective protection for interfaces with more than four signals (e.g., for six control loops). Since the surge-resistant PE snap-in foot establishes a local shield to ground bond already during assembly, this saves both time and money.
