>>>>>型号:FBM237 RH914XS  接口模块   具有坚固的挤压铝外壳 

【功能描述】

品牌/制造商：福克斯波罗

尺寸：20厘米*6.2厘米*15厘米

重量：0.4千克

原产国： 美国

描述：接口模块

FBM237包含8个0-20 mA模拟输出通道。在控制系统可靠性很重要的情况下，FBM237 可能安装了冗余模块。这允许所有八个输出

在存在单个故障的情况下以及在拆卸和更换可疑模块期间保持运行。0-20 mA信号与HART@现场设备在电气上兼容。

FBM237 0至20 mA输出模块包含8个通道。输出与其他通道和接地电隔离。该模块可以用作单个单元，也可以用作冗余对(两个

FBM237)。

当用作冗余对时，现场输出信号连接到一个公共端接组件。该对中的每个模块独立地将输出保持在其指定的输出值。

Description: Interface module

The FBM237 contains eight 0-20 mA analog output channels. When control system reliability is important, redundant modules may be installed on the FBM237. This allows all eight outputs

Maintain operation in the presence of a single fault and during removal and replacement of suspect modules. The 0-20 mA signal is electrically compatible with HARt@field equipment.

The FBM237 0 to 20 mA output module contains eight channels. The output is electrically isolated from other channels and ground. The module can be used as a single unit or as a redundant pair (two

FBM237).

When used as a redundant pair, the field output signal is connected to a common termination component. Each module in the pair independently keeps the output at its specified output value.

peculiarity

The main features of the FBM237 are:

Eight 20mADC analog output channels

0 Each output channel is electrically isolated

Single or redundant module

0 Rugged design for G3 class (harsh) environments

The housing port termination Assembly (TA) is used to connect local or remote field cables to the FBM237

0 TA is used to output bypass stations for maintenance operations

The 3-layer terminal components for each channel of the internal and/or external loop powered transmitter are maintained during output 0.

0 The FBM237 is electrically compatible with standard HART signals.

Physical design

The FBM237 has a modular design with a robust extruded aluminum housing for the physical protection of the circuit. Enclosures designed for mounting FBM according to ISA standard S71.04

For all levels of environmental protection up to harsh environments (G3 class).
