Description
Fieldbus Modules provide the interface between process sensors/actuators and the redundant Fieldbus. The modules appropriately convert the electrical input/output signals used by field devices to permit communication with these devices via the
Fieldbus. The Fieldbus Modules available for use with I/A Series systems are partitioned into three categories; main modules, expandable main modules, and expansion modules.
Main Modules
Each main module independently connects to the Fieldbus, has a fixed (that is, non-expandable) capacity of field input/output channels, and performs the signal conversions and other related operational executions required for these resident input/output channels. All main modules contain the following:
Digital processor
Dual transceivers (for Fieldbus communications)
Memory
dc/dc power converter (accepts redundant power inputs)
Security logic
Power security and on-line self-check circuits.
