FBM216 P0922VV Redundant HART® Communication Input Module

Description

FBM216 P0922VV Redundant HART® Communication Input Module

The FBM216b HART Communication Redundant Input Interface Module contains
eight individually isolated input channels. It supports any mix of standard 4 to 20 mA
devices and HART devices (the signals are electrically compatible).
A pair of modules combines to provide redundancy at the fieldbus module (FBM)
level, with field inputs wired to one common termination assembly (see Figure 1, page
4). In this configuration, one FBM216b is the Master, and the other is the Tracker.
The FBM216b can serve as a HARTcommunications field device host, enabling
Foxboro™ DCS 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 it cannot support the burst
communication mode. These commands are implemented using the Foxboro DCS
Field Device Expert for HART. For details, see Field Device Expert for HART Devices
Control and I/O (PSS 41S-10FDMHRT).
The FBM216b provides individually isolated power supplies to power each of the eight
channels.
Optionally, the channels for this module 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 help prevent HARTcommunication channel
crosstalk.

FBM216

• 8 individually isolated analog input channels. Each channel accepts 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 signal
• Module pair offers redundancy at the FBM level
• 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 signal from the HART
devices
• Support for the HART universal commands necessary to interface the field device
with the Foxboro DCS database
• Per channel galvanic isolation of each of the eight input channels from each
other, ground and module logic
• Rugged design suitable for enclosure in Class G3 (harsh) environments per ISA
Standard S71.04
• High accuracy achieved by sigma-delta conversions for each channel
• Termination Assembly (TA) for locally or remotely connecting field wiring to the
FBM216b
• TA provide for per channel internally and/or externally loop powered transmitters
