Zener diode barrier.
TURCK, MINNEAPOLIS. The new MZB series Zener diode barrier limits excess energy before it reaches a hazardous area. If an electrical fault (such as an overvoltage) occurs in the non-hazardous region of the barrier, the Zener diodes restrict the voltage available to the hazardous area circuits, while the series resistance regulates the current. The circuit contains a fuse designed to rupture should excess energy continuously applied to the barrier exceed the design criteria for the loop. The design includes removable terminals with 6.33 mm-wide channels, each fitted with two stages of pulse-tested Zener diodes and a terminating resistor. The MZB series features a bussed power feed, and offers both relay and solid-state switch models.
