Description

GE IS420UCSBHЗA

This is a safety module produced by GE Fanuc for its Mark VIe control system. It is the core component of the system that implements safety-critical functions.

 

Core Product Overview

• Product Name: Mark VIe Safety Module

• Model Number: IS420UCSBH3A

• Manufacturer: General Electric (GE)

• Product Line: Mark VIe Control System

Primary Function and Purpose

The IS420UCSBH3A is a Safety Controller. Its main purpose is to execute logic functions related to machine and equipment safety. It is specifically designed to process safety-critical input signals (e.g., from emergency stop buttons, safety door switches, light curtains) and, based on pre-defined safety logic, control output signals to final elements (such as contactors, safety relays). This ensures that an industrial process can be safely stopped or placed into a safe state in the event of a hazardous condition.

Key Features

1. Safety Rating:

   • It complies with stringent international safety standards such as IEC 61508 and IEC 62061, and is typically capable of achieving Safety Integrity Level (SIL) 3. This means it is suitable for applications with very high safety requirements.

2. Integration within the Mark VIe System:

   • This module plugs directly into a Mark VIe rack and communicates at high speed with other controllers (e.g., the IS420UCSCH1A primary controller) and I/O modules in the system via the backplane.

   • It integrates seamlessly with the Mark VIe system’s engineering tool suite (e.g., ToolboxST) for easy configuration, programming, and diagnostics.

3. Redundancy Support:

   • To further enhance system reliability and availability, the IS420UCSBH3A can typically be configured for redundant operation. Two safety modules run in parallel; if one fails, the other can take over control seamlessly, ensuring continuous safety function.

4. Dedicated Safety Protocol:

   • It uses a protocol specifically designed for safety communications, ensuring the integrity and reliability of safety-related data transmission and preventing safety function failure due to data corruption.

5. Diagnostic Capabilities:

   • The module features robust internal diagnostics, continuously monitoring its own health status and the state of its input/output circuits. It triggers a safety action upon detecting a fault.

Typical Applications

This safety module is widely used in industrial sectors with extremely high demands for safety and reliability, particularly in:

• Gas and Steam Turbine Control Systems

• Wind Turbines

• Oil & Gas Production Platforms and Pipeline Compression

• Critical Process Industries, such as Chemical and Pharmaceutical

Differentiation from Similar Models

Within the Mark VIe system, you may encounter similar models, such as the IS420UCSCH1A. The primary distinction is:

• IS420UCSBH3A: A Safety Controller dedicated to processing safety logic, achieving SIL 3 rating.

• IS420UCSCH1A: A Primary/General Controller responsible for handling routine process control logic, typically used for non-safety-critical or lower safety-integrity applications.
