GE Fanuc IC670ALG620 4-Channel RTD Input Module Field Control

Overview

The IC670ALG620 module from GE Fanuc is a high-precision RTD input interface designed for Field Control systems. It supports four independent channels and is compatible with both 3-wire and 4-wire RTD sensors, including Platinum, Nickel, Nickel/Iron, and Copper types. The module converts resistance measurements into accurate temperature data for process monitoring, control applications, and industrial automation systems.

Key Features

• Four fully isolated RTD input channels for flexible sensor integration

• Supports 3-wire and 4-wire RTD configurations

• Configurable measurement ranges: 0–500 Ω or 0–3000 Ω

• Outputs in resistance (Ω), Celsius (°C), or Fahrenheit (°F) with tenths resolution

• Built-in diagnostics for open-wire, short-circuit, overrange/underrange, and high/low alarms

• No external loop power required, reducing installation complexity

• Industrial-grade reliability for continuous operation

Technical Specifications

Applications

Ideal for process control systems, distributed control stations, and temperature monitoring in industrial environments where precise RTD measurements are required. It integrates seamlessly with GE Field Control systems for automated and reliable operation.

FAQ

Q: Can the module measure multiple RTD types simultaneously?
A: Yes, each channel can be individually configured for Platinum, Nickel, Nickel/Iron, or Copper RTDs.

Q: Is external power required for the RTDs?
A: No, the module does not require loop power; it draws power directly from the Bus Interface Unit.

Q: How is configuration performed?
A: The module is configured via a handheld device connected to the main Bus Interface Unit.
