Description
The Foxboro FBM203 RH914SV is a high-performance Fieldbus Module (FBM) designed to interface with resistance temperature detectors (RTDs) in the Foxboro DCS system. It provides eight galvanically isolated input channels for 2- or 3-wire RTD sensors and supports a resistance range of 0 to 320 ohms.
The module performs accurate signal conversion from field sensors to the optionally redundant fieldbus. Its rugged design meets Class G3 (harsh) industrial environments, and it supports flexible installation via DIN rail or modular rack-mounted baseplates.
Key Features
-
Eight RTD Input Channels: Each channel is galvanically isolated.
-
2- or 3-Wire RTD Support: Compatible with a 0 to 320 Ω resistance range.
-
High Accuracy: Sigma-delta data conversion provides new analog input values every 25 ms.
-
Configurable Integration Period: Reduces process noise and eliminates power line frequency effects.
-
Rugged Industrial Design: Meets Class G3 (ISA S71.04) contamination standards.
-
Visual Indicators: Red and green LEDs indicate operational status.
-
Easy Maintenance: Removable/replacable modules on DIN rail or rack-mounted baseplate (supports 4–8 FBMs).
-
Fieldbus Communication: Interfaces with redundant 2 Mbps module Fieldbus via either path (A or B).
-
Termination Assemblies: DIN rail or baseplate-mounted, supporting multiple wiring types and sizes.
