Product Introduction
FBM206 P0916CQ is an 8-channel pulse input module produced by Foxboro, belonging to the I/A series. This module is widely used in automation control systems in chemical, petrochemical, electric power, metallurgy and other industries.
Measurement of a machine's rotational speed is often accomplished using a device that transmits high speed pulses. The FBM206 provide the means to accept up to eight of these pulse signals (up to 25kHz) and provide the values to the Foxboro Evo™ system. The FBM206b accepts up to four pulse inputs and provides up to four 0 to 20 mA outputs for associated controls.

Product Details
STANDARD DESIGN
The FBM206/206b module has 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.
VISUAL INDICATORS
Light-emitting diodes (LEDs) incorporated into the front of the module provide visual status indications of Fieldbus Module (FBM) functions.
EASY REMOVAL/REPLACEMENT
The modules can be removed/replaced without removing field device termination cabling, power or communication cabling.
FIELDBUS COMMUNICATION
A Fieldbus Communication Module or a Control Processor interfaces the 2 Mbps module Fieldbus used by the FBMs. FBM206 accepts communication from either path (A or B) of the redundant 2 Mbps Module Fieldbus – should one path fail or be switched at the system level, the module
MODULAR MODULE MOUNTING
The modules mount 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.
TERMINATION ASSEMBLIES
Field I/O signals connect to the FBM subsystem via DIN rail mounted TAs. The TAs used with FBM206 are described in "FUNCTIONAL SPECIFICATIONS – TERMINATION ASSEMBLIES" on page 7.

Table 1. Certification for Termination Assemblies
| Type | Certification(a) |
| Type 1 | TAs are UL/UL-C listed as suitable for use in Class I; Groups A-D; Division 2 temperature code T4 hazardous locations. They are DEMKO certified EEx nA IIC T4 for use in Zone 2 potentially explosive atmospheres. |
| Type 2 | TAs are UL/UL-C listed as associated apparatus for supplying non-incendive field circuits Class I; Groups A-D; Division 2 hazardous locations when connected to specified 200 Series FBMs and field circuits meeting entity parameter constraints specified in Standard and Compact 200 Series Subsystem User's Guide (B0400FA). They are also DEMKO certified as associated apparatus for supplying field circuits for Group IIC, Zone 2 potentially explosive atmospheres. Field circuits are also Class 2 limited energy (60 V DC, 30 V AC, 100 VA or less) if customer-supplied equipment meets Class 2 limits. |
