PXC Modular Series

Figure 1. PXC Modular.

Description

The PXC Modular Series (Programmable Controller–

Modular) is a high-performance modular Direct Digital

Control (DDC) supervisory field panel, which is an

integral part of the APOGEE® Automation System.

The PXC Modular operates stand-alone or networked

to perform complex control, monitoring, and energy

management functions without relying on a higher-

level processor.

● Up to 100 modular field panels communicate on a

peer-to-peer network.

● With the addition of TX-I/O modules and a TX-I/O

Power Supply on a self-forming bus, the PXC

Modular can directly control up to 500 points.

See the APOGEE Wiring Guidelines for Field

Panels and Equipment Controllers (125-3002)

for information on setting up this

configuration.

With the addition of an Expansion Module, the PXC

Modular also provides central monitoring and control

for distributed Field Level Network (FLN) devices.

Features

● Modular hardware components match initial

control requirements while providing for future

expansion.

● Automation Level Network (ALN) support for peer-

to-peer communications over industry standard

10/100Base-T TCP/IP networks or RS-485 P2

networks.

● Optional support for P1 FLN devices.

● Optional support for P1 Wireless FLN.

● Optional operation as a P1 device with default

applications.

● HMI RS-232 and USB ports, which provide laptop

connectivity for local operation and engineering.

● DIN rail mounted device with removable terminal

blocks simplifies installation and servicing.

● Proven program sequences to match equipment

control applications.

● Built-in energy management applications and

DDC programs for complete facility management.

● Comprehensive alarm management, historical

data trend collection, operator control, and

monitoring functions.

● Sophisticated Adaptive Control, a closed loop

control algorithm that auto-adjusts to compensate

for load/seasonal changes (License required with

Firmware revision 2.8.18 and higher).

● PXM10T and PXM10S support: Optional LCD

Local user interface with HOA (Hand-off-auto)

capability and point commanding and monitoring

features.

PXC Modular Series Hardware Hardware PXC Modular ● The Modular is a microprocessor-based multitasking 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 timeconsuming program and database re-entry in the event of an extended power failure.

PXC Modular Series Global Information Access For example, in monitoring applications, the control panel can be customized with the number and type of points to match the sensor devices. For monitoring and controlling a large number of (on-off) fans or motors, more digital points can be added (see Figure 6). Figure 6. PXC Modular, TX-I/O Power Supply, and TX-I/O Modules.

PXC Modular Series Built-in Direct Digital Control Routines Built-in Direct Digital Control Routines The PXC Modular provides stand-alone Direct Digital Control (DDC) to deliver precise HVAC control and comprehensive information about system operation. It receives information from sensors in the building, processes the information, and directly controls the equipment. The following functions are available in the PXC Modular: • Adaptive Control, an auto-adjusting closed loop control algorithm.
