TC Compact Series for BACnet Networks

Figure 1. TC Compact Series Controllers

(TC-24 and TC-36 shown).

Description

The TC 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 TALON

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 TC 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 TC Compact operates stand-alone

or networked to perform complex control, monitoring,

and energy management functions without relying on

a higher-level processor.

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

terminations. Selected models in the Compact Series

provide the following options:

● 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 TC-

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.
