Input/Output Channels Four 0 to 20 mA dc analog input channels and four 0 to 20 mA dc analog output channels. Each channel is isolated and independent.
Input/Output Range (Each Channel) : 0 to 20.4 mA dc
Communication : Communicates with its associated FCM or FCP via the redundant 2Mbps module fieldbus.
Power input voltage range (redundant) : 24 V dc +5%, -10%
Power consumption : 10 W (maximum) total for redundant pair
Product type : I/O Interface Module (Redundant)
Manufacturer : Foxboro
Foxboro FBM205 Interface Module. 0 to 20 mA I/O (Redundant) Simple Type: Interface Module
The FBM205, 0 to 20 mA I/O Interface (Redundant) contains four redundant 0 to 20 mA dc analog input channels and four redundant 0 to 20 mA dc analog output channels.
The inputs/outputs are galvanically isolated from other channels and ground.
A redundant pair of the modules combine to provide redundancy at the Fieldbus Module (FBM) level, with field I/O wired to one common termination assembly (see Figure 1).
Each module independently attempts to hold the output(s) at its specified output value(s), and each independently reports its observed value of the inputs.
A redundant analog input and redundant analog output block in the control software validates each input and output in conjunction with information to/from the module.
