GE IC693ALG221 4-Channel Current Input Module

Description

GE IC693ALG221 4-Channel Current Input Module

Product Dimensions：

The GE Fanuc IC693ALG221 is a high-performance Analog Input Module for the Series 90-30 Programmable Logic Controller (PLC) system. It is designed to interface the PLC with various analog sensors to monitor processes in real-time.

## 1. Product Overview

The IC693ALG221 provides 4 input channels, each capable of converting an analog current signal into a digital value for use by the CPU. This module is specifically designed for current loops, making it ideal for industrial environments where long-distance signal transmission is required.

## 2. Technical Specifications

The following table summarizes the key hardware parameters:

## 3. Key Product Advantages

• High Precision: With 12-bit resolution, it provides the accuracy needed for sensitive pressure, temperature, and flow measurements.

• Fast Processing: A 2ms update rate ensures that your PLC logic is reacting to real-world changes almost instantaneously.

• Easy Configuration: It uses the standard GE Fanuc configuration software (Proficy Machine Edition or Logicmaster), requiring no complex manual calibration.

• Robust Isolation: Provides electrical isolation between the field circuitry and the PLC backplane, protecting the CPU from external surges.

## 4. Important Considerations (Precautions)

• External Power: This module requires an external +24VDC power supply to power the current loops if the sensors are not self-powered.

• Shielding: To prevent EMI (Electromagnetic Interference), it is highly recommended to use twisted-pair shielded cable for all analog signals.

• Module Placement: While it can be installed in any slot of a Series 90-30 baseplate, avoid placing it immediately next to high-voltage AC modules to reduce noise.

• Current Limitation: Do not exceed the maximum input current rating, as this can damage the precision resistors inside the module.

## 5. Common Applications

The IC693ALG221 is widely used in process control industries, including:

• Water Treatment: Monitoring flow rates and tank levels via 4-20mA sensors.

• Oil & Gas: Interfacing with pressure transducers and gas analyzers.

• HVAC Systems: Reading humidity and temperature transmitters.

• Manufacturing: Speed control feedback for Variable Frequency Drives (VFDs).
