Description

The TC Compact Series Unitary Equipment

Controller (Programmable Controller–Compact) for

BACnet networks is a high-performance Direct

Digital Control (DDC) equipment controller, which is

an integral part of the TALON Automation System.

The controllers are classified as a BACnet

Advanced Application Controller (B-AAC) with

support for BACnet MS/TP protocol.

The TC Compact UEC 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 Unitary Equipment Controller 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 MS/TP on RS-485

Features

 BACnet Testing Laboratories (BTL) certified

Classified as BACnet Advanced Application

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

protocol for specific models.

 Message control for terminals, printers, pagers,

and workstations.

 HMI RS-232 and USB port, which provides

laptop connectivity for local operation and

engineering.

 Extended battery backup of Real Time Clock.

 Auto Save and persistent database backup and

restore within the controller.

 PXM10T and PXM10S support: Optional LCD

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

capability and point commanding and

monitoring features.

 An extended temperature range for the control

of rooftop devices.

Compact Series Unitary

Equipment Controller

The TC Unitary Equipment Controller (UEC) is an

MS/TP device, that can be configured as a

programmable, stand-alone device or as a

networked device on the BACnet MS/TP ALN

(Automation Level Network) or FLN (Field Level

Network) device.

 A Human Machine Interface (HMI) port, with a quick-connect phone jack (RJ-45), uses RS-232 protocol to support operator devices (such as a local user interface or simple CRT terminal), and a phone modem for dial-in service capability.  A USB Device port supports a generic serial interface for an HMI or Tool connection. The USB Device port does not support firmware flash upgrades.  The program and database information stored in the UEC RAM memory is battery-backed.
