Description
The FBM207/b/c Voltage Monitor/Contact SenseInput Module functions as a 16-channel DC voltagemonitor or 16-channel contact sensor. Each channelaccepts a 2-wire input from a DC voltage source(FBM207) or pair of contacts or solid state switches(FBM207b/ FBM207c). Associated termination assemblies (TAs) support discrete input signals atvoltages of 60 V DC, 120 V AC/125 V DC, or 240 VAC. For voltages higher than 60 V DC, the TAs haveadditional signal conditioning hardware that providesvoltage attenuation and optical isolation.
The module performs signal conversion required tointerface electrical input signals from field sensors tothe redundant module Fieldbus. In addition, itexecutes programs for Discrete Input, Ladder Logic,Pulse Count, and Sequence of Events, withconfigurable options of Input Filter Time.
The module can be used as a single unit, or as aredundant pair (two FBM207s). When used as aredundant pair, the modules combine to provideredundancy at the Fieldbus Module (FBM) level, withfield input signals received from one commontermination assembly though a redundant adapteraffixed to the FBMs' baseplate. The input current forredundant modules is doubled. A redundant digitalinput block in the Foxboro Evo™ Control Softwarevalidates each input in conjunction with informationto/from the module, and selects the input with thehighest quality for processing in the control strategy.In a redundant configuration, contact sense powerfrom each module is diode OR'd together in theredundant adapter to assure redundant power.
A redundant contact input function block, CINR, isused for each redundant pair of inputs. The CINRblock handles input reads and initialization logic forthe redundant channels. On each execution cycle ofthe CINR block, identical reads are sent to bothmodules, fully exercising the fieldbus and the logiccircuitry of each module.
FEATURES Key features of the FBM207/b/c modules are: - Sixteen discrete inputs - Supports discrete input signals at voltages of: • 15 to 60 V DC - contact sense • 120 V ac/125 V DC - voltage monitoring orswitch inputs • 240 V ac - voltage monitoring or switchinputs - Each input is galvanically isolated. Group isolatedwith external excitation - Single or redundant modules - Rugged design suitable for enclosures in ClassG3 (harsh) environments - Executes programs for Discrete Input, LadderLogic, Pulse Count, and Sequence of Events withconfigurable Input Filter Time option - Termination Assemblies (TAs) for locally orremotely connecting field wiring to the FBM207 - Termination Assemblies for per channel internallyand/or externally loop powered devices - Various Termination Assemblies (TAs) haveadditional signal conditioning hardware thatprovides voltage attenuation and optical isolation.
