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.

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.
