Key Product Details
Manufacturer:Foxboro(formerly Invensys,now part of Schneider Electric)
Part Number:P0914WH
Model Designation:FBM207B
Product Type:Channel Isolated 16-Input Voltage Monitor/Contact Sense Module
Core Functionality
The FBM207B P0914WH functions as a 16-channel input module capable of:
DC Voltage Monitoring:Each channel can accept a 2-wire input from a DC voltage source.
Contact Sensing:It can act as a 16-channel contact sensor,accepting inputs from pairs of contacts or solid-state switches.
Key Features and Specifications
Input Channels:16 discrete input channels.
Isolation:Each discrete input is galvanically isolated from other channels and ground,ensuring signal integrity and protection.
Input Voltage Support:
FBM207b(this specific model):Designed for 24 V DC contact sense.
Other FBM207 variations(FBM207,FBM207c)support different voltages(e.g.,60 V DC,120 V AC/125 V DC,240 V AC)and functions(voltage monitoring,switch inputs).
Termination Assemblies(TAs):The module uses external termination assemblies to match the externally powered voltage level and provide additional signal conditioning hardware,including voltage attenuation and optical isolation for higher voltages.
Redundancy:The FBM207B can be used as a single unit or as a redundant pair(two FBM207s)for enhanced reliability,with control blocks managing the redundancy.
Fieldbus Communication:Communicates via a redundant 2 Mbps module Fieldbus with associated Fieldbus Communications Modules(FCM)or Field Control Processors(FCP).
Program Execution:The module executes programs for Discrete Input,Ladder Logic,Pulse Count,and Sequence of Events,with configurable options like Input Filter Time.
Rugged Design:Features a robust extruded aluminum exterior,making it suitable for enclosures in Class G3(harsh)environments.
Indicators:Includes visual LED indicators for operational status and discrete input states.
Easy Maintenance:Designed for easy removal and replacement without disturbing field device termination or communication cabling.
Operating Conditions:
Operating Temperature:-20°C to 60°C(-4°F to 140°F)(some sources cite up to 70°C).
Storage Temperature:-40°C to 70°C(-40°F to 158°F).
Relative Humidity:5%to 95%(non-condensing).
