安全栅简介
安全栅又称安全保持器。本安回路的安全接口，它能在安全区和危险区之间双向转递电信号，并可限制因故障引起的安全区向危险区和能量转递。一般安全栅有齐纳式、隔离式.
由于安全栅被设计为介于现场设备与控制室设备之间的一个限制能量的接口，因此无论控制室设备处于正常或故障状态，安全栅都能确保通过它传送给现场设备的能量是本质安全的

The UPR 05 Power Rail is a complete unit consisting of the electrical insert and an aluminum 35 x 15 x 2000 mm DIN rail.Devices are simply snapped onto it for an electrical connection.Without the use of a Power Rail, the power supply to the device is directly through the device terminals.Accessories:103367_e n g 06.03.2002。
