BEI IDEACOD安全模块EM系列介绍及选型
该本质安全屏障模块是BEI固有安全编码器的完美补充，当一起使用时，构成了针对I级和II级1区（0区）危险环境中编码器操作的完整工程解决方案。这个单一的屏障为具有差分正交输出和索引的增量编码器提供了电源和信号隔离。当使用单独的电源和信号屏障时，这种多合一的方法节省了成本，不便和系统设计时间。该隔离层是电隔离的，从而消除了维持高完整性接地的额外成本。通过差分线路驱动器输出，该屏障可用于可靠地传输高达500英尺，带宽高达250 kHz的信号。它围绕标准DIN导轨安装（类型EN 50022，35 mm X 7.5 mm）设计，可轻松安装在标准机柜中。每个模块都提供一定长度的DIN导轨。该模块可直接直接卡到DIN导轨上，即可使用。
本质安全屏障模块经过认证，可以安装在Class I，Div。中。 2（区域2）区域。
正确连接后，差分数据信号具有固有的抗噪声能力，因为它被拒绝作为共模信号。但是，如果编码器和屏障之间的连接断开或断开不正确，则它可以充当天线并仍然产生信号。 BEI的固有安全屏障（仅28V / V和28V / 5）上提供了开路检测（ISD）选项。如果数据线被切断或未正确连接，则ISD选件可以检测到连接阻抗的变化，并使差分信号的两条腿上的输出数据变低。这会创建一个错误的逻辑状态，操作员可以使用它来暂停或修改过程。
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.
