Honeywell SAI-1620M Analog Input 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 modems 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.

variables

• Safe-state (FAILOPT) behaviors configurable on a

per channel basis

• Output read-back and alarm on discrepancy

• Non-incendive output

FAILOPT

Series C AO module supports the FAILOPT parameter on a per channel basis. The user can configure each channel to

either HOLD LAST VALUE, or SHED to a SAFE VALUE. The Output will always go to zero, the safe state, if the IOM

device electronics fails.

Open-wire Detection

This Series C IO function will be able to detect and annunciate open field wire with a Channel Soft Failure indication.
