Product Introduction

The IS220YAICS1AJ analog I/O Pack module belongs to the Mark VIe / Mark VIeS control system series. It is used for the acquisition, processing, and output control of analog signals in industrial automation systems and is a key component of control systems for gas turbines, steam turbines, and large industrial equipment. The analog input and output functions can be used to collect analog signals from on-site sensors (such as temperature, pressure, vibration, flow, etc.).

Product Details

In the Mark VIe control system architecture, IS220YAICS1AJ acts as an I/O Pack and has the following functions:
Analog signal acquisition (Analog Input)
Control signal output (Analog Output)
Communication with the controller (such as UCSB)
Data preprocessing and filtering
Safety control and system feedback

Unlike traditional PLC systems, the Mark VIe adopts a distributed architecture. The I/O modules are no longer concentrated in the rack but are deployed separately on-site, and they are connected to the controller via industrial Ethernet.

In the Mark VIe system, IS220YAICS1AJ can be used for:
Dual redundant system
Triple redundant system (TMR)

Installation Instructions

IS220YAICS1AJ belongs to the I/O Pack + Terminal Board (terminal board) combination structure:
I/O Pack: Core for Data Acquisition and Communication
Terminal Board: Interface for On-Site Signal Wiring

01.

Install the terminal board

Install the terminal plate at:
DIN rail or
Fixed position of the control cabinet

02.

Connect the I/O Pack module

Align the IS220YAICS1AJ with the terminal board interface
Insert the interface vertically (avoid tilting)
Confirm that it is fully inserted
Tighten the fixing screws

03.

Ethernet communication connection

The IS220YAICS1AJ provides two RJ45 interfaces:
Connection method:

Port 1 → IONet network
Port 2 → Redundant or cascaded

04.

Debugging and Configuration

Use the official software of GE: ToolboxST
Add the I/O Pack module
Assign IP addresses
Configure channel parameters
Check the status of IONet

How to check the communication status through the panel indicator lights

The front panel of IS220YAICS1AJ usually includes the following key LEDs

LINK (green) - Network connection status

Each Ethernet port has a LINK LED Constantly on (ON) → Ethernet physical connection has been established (communication foundation is normal)
Off (OFF) → No network connection (problem with network cable/switch/port)

TxRx (yellow) - Data communication status

Blinking → Data is being sent/received (communication is normal)
Constantly on or not blinking → Connection exists, but no data communication
Off → No communication

ATTN (Red) - Module Status/Communication Abnormal Indication

Off → Normal operation (communication is normal)
Always on → Fault (unable to operate)
Fast flashing → Configuration error / No terminal board / Program error
Slow blinking → Position identification (not a fault)

PWR (green) - Power status

Note: Power-on does not equal module communication.

On → Normal power supply
Off → No power supply
