Allen-Bradley 1746-INT4 Thermocouple Input Module

Allen-Bradley 1746-INT4 is an isolated thermocouple and millivolt input module. It is designed for use with the SLC 500 series of programmable logic controllers (PLCs). This module offers four isolated input channels. It connects various thermocouple and millivolt sensors to your PLC system.

Key Features

• Isolated Inputs: Each channel is isolated to prevent electrical noise and interference. This ensures other channels or the PLC remain unaffected.
• Thermocouple and Millivolt Compatibility: The module supports a wide range of thermocouple types and millivolt signals. This versatility suits various temperature measurement applications.
• Digital Conversion: The module converts analog signals from thermocouples and millivolt sensors into digital values. The PLC can then easily process these digital values.
• Image Table: It stores the converted data in an image table. This setup allows easy access by the PLC processor.
• SLC 500 Compatibility: Specifically designed for the SLC 500 series PLCs, it integrates seamlessly into your existing automation system.
