Honeywell TC-OAV081 Compatible Analog Output Module

Overview

Plants running the TotalPlant™ Solution (TPS) system need to avoid obsolescence by employing modern technology. 

TPS, introduced in 1998, helped establish open plant automation with a host of advanced applications. 

However, its users are now dealing with compliance issues related to new safety regulations as well as increasing system support challenges.

With Experion LCN, existing control strategy, field terminations, applications, history and graphics can be retained, 

allowing users to focus on high value improvements. 

It minimizes operating disruptions, maintains overall consistency and delivers optional lifecycle advantages with virtualization. 

It also opens the door to Industrial Internet of Things (IIoT) by Honeywell, an approach that connects people to assets, 

automates predictive analytics, and enables increased collaboration.

Analog Output with HART – CC-PAOH01

Function

The Analog Output (AO) Module delivers high-level constant current to actuators and recording/indicating devices.

Notable Features

• Extensive self-diagnostics

• Optional redundancy

• HART-capable, multivariable instruments

• Multiple moems for fast collection of control

How Does It Work?
Expanding on the Enhanced TPS Node capabilities, the Experion LCN further enables continuous innovation for Honeywell customers. 

Using the proven Experion Fault Tolerant Ethernet (FTE) infrastructure, a new ELCN Bridge connects Experion to Classic Coax LCN.  
Once this connection is established, the LCN coax connection can be removed one LCN node at a time. 

Instead of a hardware connection for every Experion TPS Node, only one redundant ELCN Bridge pair is needed to enable virtualization.

Features

All Series C components feature an innovative design that supports enhanced heat management.

This unique look provides a significant reduction in overall size for the equivalent function.

The unique features of Series C I/O include:

• I/O Module and field terminations are combined in the same area. The I/O Module is plugged

into the IOTA to eliminate the need for a separate chassis to hold the electronics assemblies.

• Two level “detachable” terminals for landing the field wiring in the enclosure, providing easier

plant installation and maintenance.

• Field power is supplied through the IOTA, with no need for extra power supplies and the

associated craft wired marshalling.

• Redundancy is available directly on the IOTA without any external cabling or redundancy control

devices, by simply adding a second IOM to an IOTA.

• The Series C innovative styling is one of its unique features. This styling includes features to

facilitate the effective use of control hardware in a systems environment. These features include:

• Vertical mounting for more effective wiring since most field wiring applications require entry from the top or bottom of

the systems cabinet.

• An “information circle” for a quick visual cue to draw the Maintenance Technician’s eye to important status

information.

• “Tilted” design for effective heat management within the cabinet enclosure. Since Series C allows for a significant

increase in cabinet density, an effective heat management system is critical for high systems availability.

• Input and output circuits are protected from shorts to alleviate the need for in-line fusing, reducing installation and

maintenance costs.
