GE IS230PCAAH1B Mark VIe I/O Module

GE IS230PCAAH1B Core Analog I/O Module for Mark VIe

Product Introduction

The IS230PCAAH1B from General Electric is a key component in the Mark VIe series. It handles analog signals for gas turbine control. This I/O module provides 25 inputs and multiple 4-20 mA outputs. It also supports LVDT excitation, servo drivers, and 0-10 V DC analog inputs. You can use it in simplex, dual, or triple-modular redundant (TMR) systems. Because the module integrates several boards, the entire unit is the least replaceable component.

Technical Specifications

The IS230PCAAH1B delivers precise analog measurement and control. Its analog 0-10 V DC inputs achieve an accuracy of ±0.50%. The LVDT excitation monitor input reaches ±1.00%, while the servo driver output provides ±3.50%.

Additionally, the module requires a power supply input voltage of 28Vdc ±5%. It uses surface-mount technology for reliable operation. The operating temperature ranges from -30 to 65°C, making it suitable for harsh industrial environments.

The IS230PCAAH1B connects to a TCAT terminal board via two 68-pin cables on connectors P1 and P2. A single TCAT board can fan signal inputs to one, two, or three linked PCAA modules. For field wiring, the module edge includes 120 Euro-style box terminals.

Furthermore, the module features dual RJ45 Ethernet connectors and a P5 power connector for 28 V dc input. A separate JGPA board provides shield ground and 24 V field power connections.

Mechanical and Environmental Parameters

• Size: 33.02 cm high x 17.8 cm wide

• Technology: Surface-Mount

• Operating Temperature: -30 to 65°C

• Origin: U.S.A.

• Manual Reference: GEH-6721L

Installation Guidelines

First, mount the IS230PCAAH1B module firmly inside the cabinet. Next, attach the JGPA power connector to the P4 connector on the PCAA. Then connect two 68-pin cables from connectors P1 and P2 to the TCAT terminal board.

For proper cable grounding, only finger-tighten the mounting screws into the PCAA and TCAT. Over-tightening may prevent the module from reading the electronic ID on the TCAT. This can degrade communication performance.

Meanwhile, connect one or two Ethernet cables depending on your system configuration. The IS230PCAAH1B works correctly over either port when using a single IONet connection. For dual connections, connect ENET1 to the R controller's network.

After wiring, verify that the JGPA shield wire terminals are grounded. In most cases, these terminals connect electrically to the mounting sheet metal. However, some applications require a separate shield ground. Use insulating hardware and add a dedicated ground wire in such cases.

Finally, apply power through the P5 connector. Check the power and Ethernet status indicator lights to confirm normal operation.

Operation Overview

The IS230PCAAH1B assembly includes four different circuit boards. Because isolating a failure to a single board is difficult, the whole module is considered the least replaceable unit. You cannot replace individual boards.

The processing board inside features a fast processor with RAM and flash memory. It also includes two independent 10/100 Ethernet ports, a watchdog timer, an internal temperature sensor, and status LEDs. The module reads electronic IDs on other boards and supports local power supplies with monitoring and sequencing.

The IS230PCAAH1B operates at frame rates of 40 ms and 10 ms. Its accuracy specifications account for aging, temperature changes, power supply variation, and product tolerance. At 25°C, typical accuracy is better than the specified worst-case limit.

For example, you can use this module in simplex, dual, or TMR systems. A single TCAT terminal board can fan inputs to one, two, or three IS230PCAAH1B modules. Signals exclusive to a single module wire directly to the PCAA terminals.

Frequently Asked Questions (FAQ)

1. Can I replace individual boards inside the IS230PCAAH1B?
No. The IS230PCAAH1B is the least replaceable unit. You cannot replace separate circuit boards. The entire module must be swapped if it fails.

2. Which terminal boards work with the IS230PCAAH1B?
The module works with TCAT and TCAS terminal boards. A single TCAT board can connect to one, two, or three IS230PCAAH1B modules for TMR applications.

3. What is the accuracy of the analog inputs on the IS230PCAAH1B?
The 0-10 V DC inputs achieve ±0.50% accuracy. The LVDT excitation monitor input provides ±1.00% accuracy. These values include aging and temperature effects.

4. How do I ground the shield wires correctly?
Finger-tighten the mounting screws. Over-tightening can cause communication issues. For isolated grounding, use insulating hardware and run a dedicated ground wire from the JGPA terminal.

5. Does the IS230PCAAH1B support both simplex and TMR configurations?
Yes. You can use it in simplex, dual, or triple-modular redundant systems. For TMR, connect three IS230PCAAH1B modules to one TCAT terminal board.
