TURCK ZENER DIODE BARRIERS FOR HAZARDOUS AREAS LIMIT EXCESS ENERGY WITH A COMPACT, CONVENIENT DESIGN
| Minneapolis, Minn.—September 28, 2009—TURCK introduces MZB series Zener diode barriers, designed to effectively limit excess energy before it reaches a hazardous area. The MZB barriers provide convenient removable terminals within an extremely efficient and space-saving design—with channels as small as 6.3mm wide—to consume minimal panel space. Additionally, the MZB series features a bussed power feed and offers both relay and solid-state switch models. |
Each channel of the new MZB Zener diode barriers is fitted with two stages of pulse-tested Zener diodes and an infallible terminating resistor. If an electrical fault such as an overvoltage occurs in the non-hazardous area of the barrier, the Zener diodes limit the voltage available to hazardous area circuits, while the series resistance limits the current. Within this circuit is a fuse designed to immediately and safely rupture if the excess energy continuously applied to the barrier exceeds the design criteria for the loop.
