GE IC670ALG620 RTD Analog Input Module

Description

The IC670ALG620 module is part of GE's Field Control series.It accepts inputs from 4 independent 3-wire and/or 4-wire RTDs, including platinum, nickel, nickel/iron, or copper types.Converts RTD input levels into digital values for precise temperature measurement.

Specifications

• Input Channels: 4 channels.

• Selectable Resistance Ranges: 0–500 ohms and 0–3000 ohms.

• Measurement Units: Resistance (ohms) or temperature (Celsius/Fahrenheit).

• Data Acquisition Rates: Configurable for 50 Hz and 60 Hz line frequencies.

• Operating Temperature: -20°C to 60°C.

• Storage Temperature: -40°C to 85°C.

• Power Supply: No loop power required; the module provides excitation current for RTDs.

• Humidity Range: 5% to 95% (non-condensing).

Features

• Individual channel configuration for resistance or temperature measurements.

• Reports alarms for high/low, underrange/overrange, open wire, and input short conditions.

• Automatic A/D calibration at power-up and periodic recalibration to adjust for ambient temperature changes.

• Compact and modular design for easy integration into industrial environments.

• LED indicator for module status (e.g., normal operation, faults).
