BEI IDEACOD安全模塊EM系列介紹及選型
該本質安全屏障模塊是BEI固有安全編碼器的完美補充，當一起使用時，構成了針對I級和II級1區(qū)（0區(qū)）危險環(huán)境中編碼器操作的完整工程解決方案。這個單一的屏障為具有差分正交輸出和索引的增量編碼器提供了電源和信號隔離。當使用單獨的電源和信號屏障時，這種多合一的方法節(jié)省了成本，不便和系統(tǒng)設計時間。該隔離層是電隔離的，從而消除了維持高完整性接地的額外成本。通過差分線路驅動器輸出，該屏障可用于可靠地傳輸高達500英尺，帶寬高達250 kHz的信號。它圍繞標準DIN導軌安裝（類型EN 50022，35 mm X 7.5 mm）設計，可輕松安裝在標準機柜中。每個模塊都提供一定長度的DIN導軌。該模塊可直接直接卡到DIN導軌上，即可使用。
本質安全屏障模塊經(jīng)過認證，可以安裝在Class I，Div。中。 2（區(qū)域2）區(qū)域。
正確連接后，差分數(shù)據(jù)信號具有固有的抗噪聲能力，因為它被拒絕作為共模信號。但是，如果編碼器和屏障之間的連接斷開或斷開不正確，則它可以充當天線并仍然產(chǎn)生信號。 BEI的固有安全屏障（僅28V / V和28V / 5）上提供了開路檢測（ISD）選項。如果數(shù)據(jù)線被切斷或未正確連接，則ISD選件可以檢測到連接阻抗的變化，并使差分信號的兩條腿上的輸出數(shù)據(jù)變低。這會創(chuàng)建一個錯誤的邏輯狀態(tài)，操作員可以使用它來暫停或修改過程。
This Intrinsic Safety Barrier Module is the perfect complement to BEI’s Intrinsically Safe Encoders and, when used together,constitutes a completely engineered solution for encoder operation in Class I and Class II, Division 1 (Zone 0) Hazardous Environments. This single barrier provides both power and signal isolation for an incremental encoder with differential quadrature outputs and an index. This all-in-one approach saves the cost, inconvenience and system design time needed when using separate power and signal barriers. This barrier is galvanically isolated which eliminates the added cost of maintaining a high integrity earth ground. With differential line driver outputs, this barrier can be used to carry signals reliably up to 500 feet with a bandwidth of up to 250 kHz. It is designed around a standard DIN Rail mounting (Type EN 50022, 35 mm X 7.5 mm) for easy installation in standard enclosures. A length of DIN rail is supplied with each module. The module simply snaps directly to the DIN rail and is ready to use.
The Intrinsic Safety Barrier Module is certified to be installed in Class I, Div. 2 (Zone 2) areas.
When properly connected, differential data signals have an inherent immunity to noise since it is rejected as common mode. However if a connection between the encoder and the barrier is broken or improperly terminated it can act as an antenna and still create a signal. An open wire detection (ISD) option is available on BEI’s Intrinsically Safe Barriers (28V/V and 28V/5 only). In the event that the data line is cut or not properly connected the ISD option can detect a change in the impedance of the connection and cause the output data on both legs of the differential signal to go low. This creates an erroneous logic state that can be used by the operator to halt or modify a process.
