PXC Modular
● The Modular is a microprocessor-based multi-
tasking platform for program execution and
communication with other field panels. It scans
field data, optimizes control parameters, and
manages operator requests for data in seconds.
● The program and database information stored in
the Modular memory is protected with a battery
backup. This eliminates the need for time-
consuming program and database re-entry in the
event of an extended power failure. When battery
replacement is necessary, the Modular illuminates
a “battery low” status LED and can send an alarm
message to selected printers or terminals.
● The Modular firmware, including the operating
system, is stored in non-volatile flash memory.
● LEDs provide instant visual indication of overall
operation, network communication, and battery
status.
● Two self-forming buses are an integral part of the
flexibility of the Modular. A self-forming bus to the
right of the controller (see Figure 3) supports up to
500 points through TX-I/O™ modules. Another
self-forming bus to the left of the controller (see
Figure 5) supports hardware connection to
subsystems through Expansion Modules.
TX-I/O Modules
TX-I/O Modules are modular expansion I/O consisting
of an electronics module and terminal base. The
electronics modules perform A/D or D/A conversion,
signal processing and point monitoring and command
output through communication with the Modular. The
terminal bases provide for termination of field wiring
and connection of a self-forming bus. For more
information, see the TX-I/O Product Range Technical
Specification Sheet (149-476).
TX-I/O Power Supply
The TX-I/O Power Supply provides power for TX-I/O
modules and peripheral devices. Multiple Power
Modules can be used in parallel to meet the power
needs of large concentrations of I/O points (see
Figure 2 and Figure 3). For more information, see the
TX I/O Product Range Technical Specification Sheet
(149-476).

TX-I/O Modules.
PXC Modular Expansion Module
The Modular Expansion Module (see Figure 4)
provides the hardware connection for Field Level
Network (FLN) devices.
Using the Triple RS-485 Expansion Module, the
Modular supports up to three RS-485 networks of P1
Field Level Network devices. With the Expansion
Module the PXC Modular can also provide wireless
FLN support.

Modular Control Panels with
Application Flexibility
The PXC Modular is a high performance controller
with extensive flexibility to customize each field panel
with the exact hardware and program for the
application. As a result, the user only purchases what
is needed.
