VISUAL INDICATORS Light-emitting diodes (LEDs) incorporated into the front of the module provide visual indication of the Fieldbus Module operational status, as well as the discrete states of the individual input and output points. EASY REMOVAL/REPLACEMENT The module can be removed/replaced without removing field device termination cabling, power, or communication cabling. FIELDBUS COMMUNICATION A Fieldbus Communications Module or a Control Processor interfaces to the redundant 2 Mbps module Fieldbus used by the FBMs. The FBM241 accepts communication from either path (A or B) of the redundant 2 Mbps Fieldbus - should one path fail or be switched at the system level, the module continues communication over the active path. MODULAR BASEPLATE MOUNTING The module mounts on a DIN rail mounted baseplate, which accommodates up to four or eight Fieldbus Modules. The Modular Baseplate is either DIN rail mounted or rack mounted, and includes signal connectors for redundant Module Fieldbus, redundant independent dc power, and termination cables. SECURITY Field power for contacts or solid state switches is current limited. TERMINATION ASSEMBLIES Field I/O signals connect to the FBM subsystem via DIN rail mounted TAs. The TAs used with the FBM241/b/c/d are described in “5 A at up to 120 V ac (see “GENERAL PURPOSE PLUG-IN RELAY TERMINATION ASSEMBLY SPECIFICATIONS” on page 23)” on page 8.
