Foxboro 0399143 SY-0301060R SY-1025115C/SY-1025120E Control Module

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

optionally redundant ISCM, with a total of

16 ISCMs supported per I/A Series control

processor (FCP270 or ZCP270); a maximum of

204 modules (ISCMs, I/O modules and

200 Series FBMs) supported per FCP270 and a

maximum of 128 modules supported per

ZCP270. provided the maximum CP Fieldbus

load and intrinsically safe I/O power supply load is

not exceeded

Redundant ISCMs allow either module to control

the process. Role reversal is automatic on

detected failures

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.

This subsystem supports both the P+F intrinsically

safe I/O modules and their associated base,

extension or redundancy units for Zone 2. Div. 2 or

Zone 22 (LB-style(1)) environments or

Zone 1 or Zone 21 (FB-style(2)) environments.

Optionally redundant ISCMs are mounted directly on

the appropriate P+F unit along with the I/O modules

and power supplies, as shown in Figure 1 and

Figure 2. Only I/O modules can be mounted in the

extension units. Each I/O module can be plugged

into any desired slot on the base or extension unit.

ISCMs and power supplies are required to be

plugged into their own dedicated slots.
