Here is all you need to know
The FBM214 HART Communication Input Interface Module contains eight 4 to 20 mA group isolated analog input channels. The FBM214 supports any mix of standard 4 to 20 mA devices and HART devices.
The FBM214 serves as a HART communications field device host, enabling the I/A Series system to request and receive two digital messages per second
from the field device. The message pass-through capability can be used to support HART universal, common practice, and device-specific commands,
but not the burst communication mode. These commands are implemented using the Intelligent Field Device Configurator
The FBM214 provides a common isolated power supply to power all eight channels. Optionally, the channels can be powered by an external power
supply. However, when a common external power supply is used with two or more channels, a Cable Balun module is required to prevent channel cross
talk.
The FBM214 has a compact design, with a rugged extruded aluminum exterior for physical protection of the circuits. Enclosures specially designed for mounting the FBMs provide various levels of environmental protection, up to harsh environments per ISA Standard S71.04.
A Fieldbus Communication Module or a Control Processor interfaces the redundant 2 Mbps module Fieldbus used by the FBMs. The FBM214 module
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. The use of an external power supply common to two or more loops requires a Cable Balun Module to maintain communication signal line balance.
The module mounts on a modular baseplate which accommodates up to four or eight FBMs. The modular baseplate is either DIN rail mounted or rack
mounted, and includes signal connectors for redundant fieldbus, redundant independent dc power, and termination cables.
Eight analog input channels, each accepting one
of the following inputs:
Standard 4 to 20 mA analog sensor signal
Digital HART Frequency Shift Keying (FSK) signal superimposed on a 4 to 20 mA analog input signal.
FSK modem dedicated to each input channel for bi-directional digital communications with a HART field device
Analog to digital conversion of each of the 4 to 20 mA input signals from the HART devices
Support for the HART universal commands necessary to interface the field device with the I/A Series® system database
Galvanic isolation of the group of 8 input channels from ground and module logic
