Foxboro P92 Control 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 cost

effective 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.

For more information on these systems, refer to the

ISCM DESIGN

ISCM modules support I/A Series and HART™

communications over the standard HDLC fieldbus.

They have a compact design, with a rugged exterior

for physical protection of the electronics in

environments with a minimum ingress protection of

IP 54. P+F-provided enclosures specially designed

for mounting of the P+F intrinsically safe I/O modules

provide the appropriate level of environmental

protection (for Zone 2/Div 2 or Zone 1 applications).

The ISCM and the supported P+F I/O modules can

be removed/replaced from the base or extension unit

without removing power. Light-emitting diodes (LEDs)

incorporated into the front of the ISCM and I/O

modules indicate module status.

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.

IS/IO SYSTEM CONFIGURATION

REQUIREMENTS

The requirements in Table 1 must be met to ensure

proper system operation:

MODULAR UNIT MOUNTING

The ISCM mounts on supported P+F-supplied LB

style 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.

Redundant ISCMs must be located in the left-most

two slots in the LB-style base units. One each of the

FB-style ISCMs are located in the main and

redundancy units.

Table 2 lists the available ISCM modules and

available support equipment.
