PXC Compact Series for BACnet Networks

Figure 1. PXC Compact Series Controllers

(PXC-24 and PXC-36 shown).

Description

The PXC Compact Series (Programmable Controller–

Compact) for BACnet networks is a high-performance

Direct Digital Control (DDC) supervisory equipment

controller, which is an integral part of the APOGEE

Automation System. The controllers are classified as

either a BACnet Building Controller (B-BC) with support

for BACnet/IP or BACnet MS/TP protocols.

The PXC Compact Series offers integrated I/O based on

state-of-the-art TX-I/O™ Technology, which provides

superior flexibility of point and signal types, and makes it

an optimal solution for Air Handling Unit (AHU) control.

The PXC Compact operates stand-alone or networked to

perform complex control, monitoring, and energy

management functions without relying on a higher-level

processor.

The PXC Compact Series communicates with other field

panels or workstations on a peer-to-peer Automation

Level Network (ALN), or on the Field Level Network

(FLN), and supports the following communication

options:

● Native BACnet/IP communications over 10/100

MB Ethernet networks

● Native BACnet MS/TP on RS-485

The PXC Compact is available with 16, 24, or 36 point

terminations. Selected models in the Compact Series

provide the following options:

● Support for MS/TP or P1 FLN devices.

● Support for MS/TP FLN devices.

● An extended temperature range for the control of

rooftop devices.

● Support for Island Bus, which uses TX-I/O

modules to expand the number of point

terminations for high-speed loop control. For

PXC-36 only.

Features

● BACnet Testing Laboratories (BTL) certified

Classified as BACnet Building Controllers (B-BC)

using the BACnet/IP protocol and/or BACnet

MS/TP, or BACnet Advanced Application

Controllers (B-AAC) using the BACnet MS/TP

protocol for specific models.

● 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 3.5.1 and higher).
