FOXBORO 21h2y6b4 Intrinsically Safe I/O Subsystem

FOXBORO 21h2y6b4 Intrinsically Safe I/O Subsystem

The Intrinsically Safe I/O Subsystem provides integration between the Pepperl+Fuchs™ (P+F) modular  intrinsically safe remote I/O systems and the I/A Series® system. The Intrinsically Safe Communications  Module (ISCM) enables I/A Series control processors to view the P+F I/O modules as equivalent 200 Series  Fieldbus Modules (FBMs), which can be monitored with standard I/A Series blocks and standard InFusion™  or I/A Series system/control configurator applications such as the InFusion Engineering Environment and the  Integrated Control Configurator.

FEATURES 

 Intrinsically safe - supports Zone 2, Div. 2 or  Zone 22 (LB-style) environments or Zone 1, or  Zone 21 (FB-style) environments 

 ISCMs interface the 2 Mbps HDLC Module  Fieldbus to the FCP270 or ZCP270 

 Up to 46 (for LB-style Zone 2 Applications) or 48 (for FB-style Zone 1 Applications) P+F  intrinsically safe I/O modules supported per

 Redundant ISCMs allow either module to control  the process. Role reversal is automatic on  detected failures 

 Letterbug set through a letterbug module with  rotary switch plugged into the ISCM. 

 Monitored by standard System Manager or  I/A Series SMDH and FoxView™ displays

OVERVIEW 

The Intrinsically Safe I/O Subsystem provides  integration between the Pepperl+Fuchs (P+F)  modular intrinsically safe remote I/O systems and the  I/A Series system. The Intrinsically Safe  Communications Module (ISCM) communicates  between the two systems, as it enables I/A Series  control processors to view supported P+F intrinsically  safe I/O modules as equivalent 200 Series Fieldbus  Modules (FBMs) over the I/A Series 2 Mbps HDLC  Fieldbus. This allows the I/O modules to be  monitored with standard I/A Series blocks and  standard I/A Series or InFusion system/control  configurator applications such as InFusion  Engineering Environment and ICC.

HIGH RELIABILITY 

In redundant ISCM configurations, the redundancy of  the module pair provides very high subsystem  availability time. 

Either ISCM may be hot-swapped without upsetting  input or output communications to the other module,  or removing power from either module.

PEPPERL+FUCHS MODULAR REMOTE I/O  SYSTEMS 

The Pepperl+Fuchs modular remote I/O systems -  for Zone 2 or Zone 1 applications - are the costeffective connection of field signals in the hazardous  and the intrinsically safe areas to your process  control system via the HDLC Fieldbus. Combinable  I/O modules and high modularity offers cost-saving  installations. The P+F remote I/O systems are  characterized by high functionality and simple  handling.

Only intrinsically safe I/O modules from P+F that are  listed in this PSS are supported by the ISCM. If it is  desired to also include non-IS signals in the same  I/A Series system, then standard 200 Series FBMs  must be used for these signals.

MODULAR UNIT MOUNTING 

The ISCM mounts on supported P+F-supplied LBstyle or FB-style base or extension units, which  accommodate different quantities of P+F I/O  modules, depending on the application. The ISCM base unit includes signal connectors for  the ISCM and P+F I/O modules, redundant  independent power connections, and 2 Mbps HDLC  module Fieldbus connections for communications to  the I/A Series FCP270 or ZCP270.
