GE IS220PDOAH1A Product Introduction

GE IS220PDOAH1A is the core discrete output module in the General Electric (GE) Mark VIe series distributed control system, designed specifically for gas turbines, power plants, and industrial automation control, supporting high reliability relay control and real-time communication functions. The following is a comprehensive introduction to the product:

1、 Product Overview

IS220PDOAH1A is a high-performance discrete output control module that is connected to a discrete output terminal board via an Ethernet interface and supports control of up to 12 relay channels (depending on the terminal board type). Its core functions include:

Relay Control: Compatible with Solid State Relays (SSRs) and Electromagnetic Relays, suitable for devices such as fuel valves, starter motors, and protective relays.

Communication integration: Supports dual redundant Ethernet interfaces (RJ45), using Ethernet/IP protocol to achieve high-speed data transmission and network redundancy configuration.

Environmental adaptability: Designed for a wide temperature range (-25 ℃ to+70 ℃), suitable for harsh conditions in industrial environments.

2、 Main features and advantages

High integration design: integrate processor, data acquisition and communication functions into a single module to reduce dependence on external devices.

Four channel independent control: Each channel supports independent configuration and can simultaneously control loads such as motors, valves, alarms, etc.

High speed response: The response time from Ethernet commands to output is less than 1ms, ensuring real-time control accuracy.

Multiple protection mechanisms: built-in overload protection, overcurrent protection, and over temperature protection to prevent abnormal damage to the equipment.

Redundant configuration support: Network redundancy is achieved through dual Ethernet interfaces to enhance system reliability.

Flexible installation: support DIN rail or panel installation, compatible with TMR (the third mock examination redundancy) system.
