齐纳阻挡单元
齐纳阻挡单元是一个电路,它对输出 电压和电流设置极限值.这意味着在 危险区内,短路等情况下,短路火花 将由齐纳阻挡单元限制,使其不能产 生足够的能量使危险气体点火.

Zener Barrier
A zener barrier is a circuit which sets a limit for voltage and current of the output. This means that in a case of short circuit etc. in the hazardous area, the spark produced will be limited by the zener barrier and not able to produce sufficient energy to cause ignition of hazardous gases.
控制系统—继电器单元ACRB
The ACRB unit serves as a central point for various functions in the control system such as emergency stop chain and run chain with associated relays and also to streamline wiring to reduce cable branching etc.
