特點(diǎn):
FieldMonitor危險區(qū)域解決方案
支持本質(zhì)安全傳感器安裝沒有外部安全屏障
兼容170190雙電隔離器

本特利內(nèi)華達(dá)1701/06隔離器終端底座和170190雙電隔離器是FieldMonitor危險區(qū)域解決方案，支持本質(zhì)安全傳感器安裝，沒有外部安全屏障。

1701/06隔離器終端底座(ITB)和170190雙電隔離器是FieldMonitor*危險區(qū)域解決方案，支持本質(zhì)安全傳感器安裝，沒有外部安全屏障。您必須將FieldMonitor ITB及其相關(guān)模塊定位在非危險，2區(qū)或2區(qū)區(qū)域，而連接的傳感器可能位于1區(qū)，1區(qū)或0區(qū)區(qū)域。
170190雙電隔離器直接安裝到ITB中。該模塊消除了，安裝和連接外部安全屏障，或建立和維護(hù)齊納安全屏障所需的本質(zhì)安全接地的需要。兩種電隔離器版本可用:
該170190-01兼容170133和170172內(nèi)部雙近端*傳感器。它還適用于我們的大多數(shù)標(biāo)準(zhǔn)Bently Nevada*外部Proximitor傳感器，速度傳感器，Velomitor*傳感器和使用170180傳感器I/O模塊的加速度計。
該170190-02是專門設(shè)計用于與CEC 4-131和等效的速度傳感器。
注:可選電纜組件(p/n 138925)，當(dāng)緩沖的動態(tài)輸出需要路由到外部配線板，或任何其他需要動態(tài)信號的設(shè)備。

Features:

The 1701/06 Isolator Terminal Base (ITB) and 170190 Dual Galvanic Isolator are the FieldMonitor* hazardous area solutions that support intrinsically safe transducer installations without external safety barriers. You must locate the FieldMonitor ITB and its associated modules in non-hazardous, Division 2, or Zone 2 areas while the connected transducers may be located in Division 1, Zone 1, or Zone 0 areas.
The 170190 Dual Galvanic Isolator installs directly into the ITB. This module eliminates the need to specify, install, and wire external safety barriers, or establish and maintain an intrinsically safe ground that zener safety barriers require. Two Galvanic Isolator versions are available:
? The 170190-01 is compatible with the 170133 and 170172 Internal Dual Proximitor* sensors. It also works with most of our standard Bently Nevada* external Proximitor sensors, velocity transducers, Velomitor* sensors, and accelerometers that use the 170180 transducer I/O modules.
? The 170190-02 was especially designed to be used with the CEC 4-131 and equivalent Velocity Transducers.
Note: An optional cable assembly (p/n 138925) is available when buffered dynamic outputs need to be routed to an external patch panel, or any other device requiring dynamic signals.
