Product Overview

The FBM216 is a Foxboro by Schneider Electric HART Communication Redundant Input Interface Module. This module provides 8 individually isolated channels for connecting HART field instruments. It supports HART protocol versions 5, 6, and 7, making it a versatile choice for process automation in industries like oil and gas, chemical, and power generation. Designed for high reliability, the FBM216 enables redundant operation to maximize system uptime.

Technical Specifications Analysis

The FBM216 offers 8 individually isolated channels with point-to-point, master/slave, asynchronous, half-duplex communication at 1200 baud. It achieves 2 messages per second with error checking via parity on each byte and one CRC check byte. The module delivers analog accuracy of ±0.075% of full scale with 15-bit resolution. It includes a per-channel isolated 24 V DC ±10% loop supply. The input voltage range is 24 V DC +5% -10% with a maximum consumption of 7 W and heat dissipation of 4 W. Operating temperature ranges from -20 to +70°C for both module and termination assembly. It is suitable for Class G3 (Harsh) environments per ISA Standard S71.04.

Application Scenarios & Usage Methods

In a refinery, the FBM216 connects to HART pressure transmitters and temperature sensors, providing redundant input paths to the control system. Use the module in point-to-point mode to read process variables and diagnostic data from each instrument. The 100 ms update rate supports fast loop control. For tank farm monitoring, the FBM216 interfaces with level and flow HART devices, ensuring reliable data collection over distances up to 3030 m (10000 ft) as per HART FSK physical layer specification. The module’s galvanic isolation protects against ground loops in harsh industrial environments.

Installation Guide & Packing List

Mount the FBM216 module onto a compatible Foxboro termination assembly in a clean, dry cabinet. Ensure the 24 V DC power supply meets the input voltage range of 24 V DC +5% -10%. Connect field wiring per the termination assembly diagram, observing polarity and torque specifications. The packing list includes the FBM216 module, termination assembly (if ordered), and documentation. No additional cables or software are included.

Purchasing Advice

When selecting the FBM216, verify that your control processor supports I/A Series software v8.2 to v8.8 or Foxboro Evo Control Core Services v9.0 or later. Consider redundant module configuration for critical loops to enhance system reliability.
