RH914TN | FBM211 | 0 to 20 mA Input Module

The FBM211, 0 to 20 mA Input Module contains sixteen 20 mA dc analog input channels, each channel accepting a 2-wire analog sensor input such as a 4 to 20 mA transmitter, a line-monitored digital input signal with end of line resistors, or a selfpowered 20 mA source. The input channels are galvanically isolated from ground and module logic. The module performs the signal conversion required to interface the electrical input signals from the field sensors to the redundant module Fieldbus.
FBM211 executes an analog input application program, which provides configurable options for Conversion Time and Rate of Change Limits.

FBM211

Product parameter

• Sixteen 20 mA dc analog input channels
• Each group of eight input channels is group isolated
• Rugged design suitable for enclosure in Class G3 (harsh) environments
• Execution of an analog input application program that provides conversion time and configurable options for Rate of Change Limits
• High accuracy achieved by sigma-delta data conversions for each channel
• Termination Assemblies (TAs) for locally or remotely connecting field wiring to the FBM211
• Termination Assemblies for external or fieldbus module (FBM) powered transmitters

Application field

Field I/O signals connect to the FBM subsystem via DIN rail mounted termination assemblies, which are electrically passive. TAs for the FBM211 module are available in these forms:
• Compression screw type using Polyamide (PA) material Each FBM211 TA and its associated termination cable provide feedthrough connection between sixteen 2-wire analog input signals and the FBM211.
Loop power is provided to the field devices by a customer-supplied external dc power supply or by the FBM auxiliary +24 V dc power supply depending on the TA selected.
A removable termination cable connects the DIN rail mounted TA to the FBM via a field connector on the baseplate in which the FBM is installed. Termination cables are available in these materials:
• Polyurethane
• Low Smoke Zero Halogen (LSZH)
Termination cables are available in a variety of lengths, up to 30 meters (98 feet), allowing the TA to be mounted in either the enclosure or in an adjacent enclosure. See Table 2, page 12 for a list of termination cables used with the TAs for the FBM211.
