詳細描述德國P+F齊納式安全柵，V1-G-2M-PUP

 Reduced power consumption results in very   low heat dissipation Longer lifetime due to less heat in cabinet 
Up to 30 % space saving in the control cabinet   
 or power supplies Enables redundant power supply Avoids daisy chains
齊納式安全柵的核心元件為齊納二管，限流電阻及快速熔斷絲。
 Many devices with SIL2 and SIL3 Comprehensive international support 
International approvals and safety manuals available Clear
 and useful documentation with 2-D, 3-D drawings and EPLAN macros
Single loop integrity with one channel modules  in small 12.5 mm housing
隔離式安全柵不但有限能的功能，還有隔離功能，
Grounding directly connected with DIN-rail
Variants with field replaceable fuses provide a convenient means of disconnecting
or open-circuiting the instrument loop without interfering with the wiring,
making commissioning and maintenance operations much easier.
due to slim design of 12.5 mm HiC modules
due to slim design of 12.5 mm housings Horizontal and vertical mounting without derating  
 Single-loop integrity with one-channel modules in small 12.5 mm housings 
安全柵的主要功能為限流限壓，現場儀表可得到的能量在安全范圍內。

Simple expansion and replacement during operation Modules simply snap onto Power Rail
Line fault detection of field loops Reduced power consumption and efficient 
design result in very low heat dissipation Longer lifetime due to less heat in cabinet
Ensures group protection with fused power  feed modules
Zener barriers provide cost saving Ex-protection for various applications in process automation systems.
Maximum channel density in the 20 mm  housings – only 5 mm per channel 
它主要由回路限能單元，信號和電源隔離單元、信號處理單元組成。
 Up to four channels in 18 mm HiD modules  – up to 64 channels on one 16-position termination board
Separation of field loop by removing the fus
Z-system zener barriers are available with high density up to 2 channels / 12,5 mm width.
安全柵主要有齊納式安全柵和隔離式安全柵兩大類。
The amount of energy transferred to the hazardous location is limited to
 a safe level incapable of igniting the explosive atmosphere.
Z-system zener barriers from Pepperl+Fuchs are directly mounted on a 35 mm DIN-Rail.
 Horizontal and vertical mounting of the 8- and   16-position termination boards
Simple snap-on of modules on pre-wired  termination boards  Modules with coding pins avoid misplacements
 Reduced planning and wiring with system cables System connectors for various DCS Customized termination boards
安全柵又稱安全限能器，是本安系統中的重要組成部分。
Up to 30 % space saving in the control cabinet
Through accessories, the required grounding can be done directly on the DIN mounting rail.
Fast mounting on the DIN-rail
Highly functional modules for temperature,  frequency transmitters and strain gauges
 Setup with top-mounted switches Configuration with PC or pushbuttons
Display for monitoring Large label flaps for tagging and identificatio
