Product Overview

The GE IS200VAICH1DAA VME Analog Input Board is an industrial analog signal-interface board designed for use within compatible GE control-system architectures. As part of the GE IS200 family, the board provides an interface for analog field signals and supports the transfer of process information into the control system for monitoring, regulation, diagnostics, and automation functions.

Analog input boards are essential in industrial automation because many physical process variables are continuous rather than simply ON or OFF. Temperature, pressure, current, voltage, flow, level, and other measurements can be represented by analog electrical signals. A VME-based analog input board provides the electronic interface required to bring these measurements into a digital control architecture.

The GE IS200VAICH1DAA has listed dimensions of 280 × 150 × 25 mm and a weight of approximately 0.363 kg. Its compact board format is suitable for integration into industrial control equipment where analog measurement signals need to be acquired and transferred to a VME-based control system.

The board should be considered part of a complete control architecture rather than an independent controller. Its actual signal types, channel configuration, electrical ranges, terminal assignments, and system functions depend on the associated hardware and application.

A simplified architecture can be represented as:

Process Instrument → Field Wiring → Analog Input Interface → VME Control System → Control Logic → HMI / SCADA

What Is the GE IS200VAICH1DAA?

The IS200VAICH1DAA is a VME Analog Input Board designed to connect analog process information to a compatible GE industrial control system.

Industrial equipment frequently generates analog signals representing continuously changing physical conditions. For example, a pressure transmitter may generate a signal that changes as process pressure changes, while a temperature transmitter provides an electrical representation of temperature.

The analog input board receives these signals and provides the interface through which the control architecture can acquire the associated process information.

A simplified signal chain is:

Physical Process → Sensor / Transmitter → Field Cable → IS200VAICH1DAA → VME Control Architecture → Application Logic

The exact signal architecture should be confirmed against the host equipment and applicable engineering documentation.

Understanding VME Analog Input Boards

VME is a modular computer-bus architecture that has been used in many industrial, embedded, instrumentation, and control applications.

Within an industrial control system, a VME analog input board can serve as an interface between physical instrumentation and the digital processing architecture.

The general operating concept is:

1. A field sensor detects a physical process condition.
2. A transmitter or signal source generates an analog electrical signal.
3. Field wiring transfers the signal into the control cabinet.
4. The analog input board receives the signal.
5. The associated electronics condition and convert the information as required.
6. The VME control system receives the digitized measurement.
7. Control software uses the measurement for monitoring or control.

This architecture enables continuously varying process information to become usable data within an industrial automation system.

Function and Working Principle

Analog Signal Acquisition

The primary role of the IS200VAICH1DAA is associated with acquiring analog signals from field instrumentation.

Analog signals may represent variables such as:

• Temperature
• Pressure
• Flow
• Level
• Voltage
• Current
• Position
• Process feedback

The actual supported signal ranges and channel assignments depend on the specific system configuration.

Signal Conditioning

Industrial analog signals may require conditioning before being processed by digital control electronics.

Depending on the overall architecture, signal conditioning can involve filtering, scaling, isolation, amplification, or other interface functions.

The purpose is to provide the control system with a stable representation of the measured process variable.

Analog-to-Digital Conversion

A digital control system cannot directly process a continuously varying electrical signal in the same manner as an analog circuit. The input information therefore needs to be converted into a digital representation.

The associated analog-input electronics perform the necessary conversion so that the measurement can be processed by the control system.

Data Transfer

After acquisition and conversion, measurement data is made available to the associated VME control architecture.

The control system can then use the information for:

• Process monitoring
• Alarm handling
• Control calculations
• Feedback processing
• Trend recording
• Diagnostic functions

Analog Interface

The VME analog input board receives and interfaces the analog signals.

Processing Layer

The control processor receives digitized measurements and executes application logic.

Control Layer

Control algorithms use process information to regulate equipment.

Supervisory Layer
