GE Fanuc IC670ALG620 RTD Input Module

IC670ALG620 GE Fanuc Field Control RTD Input Module

Product Introduction

The IC670ALG620 is a Field Control RTD input module from GE Fanuc. It connects temperature sensors to a Field Control station. Engineers use it to monitor and control industrial processes. The module accepts four independent RTD inputs. Each input works with 3-wire or 4-wire sensors. Supported sensor materials include copper, nickel, nickel/iron, and platinum.

Furthermore, configuration happens through a handheld device. This programmer connects to the main Bus Interface Unit (BIU). The BIU acts as the central processing unit for the distributed control system. Users can set unused channels as inactive. They can also pick RTD types from pre-defined tables inside the module.

Technical Specifications

The IC670ALG620 provides four RTD input channels. Each channel supports 3-wire or 4-wire connections. Scan time is 210 ms at 60 Hz and 230 ms at 50 Hz. Digital resolution reaches 15 bits plus sign. Two resistance ranges are available: 0 to 500 ohms and 0 to 3000 ohms.

Additionally, normal mode rejection is 60 dB at 50/60 Hz across 100% span. Temperature sensitivity from 0 to 60 °C is ±0.004% of reading plus ±1.5 mV per °C referred to input. Maximum lead resistance is 5 ohms per lead.

The module draws 190 mA maximum from the BIU power supply. It detects several fault conditions. These include open RTD, input short, underrange, overrange, and high/low alarm. Such diagnostics help users find wiring or sensor problems quickly.

Mechanical and Environmental Parameters

The IC670ALG620 has one status LED at the front. A steady light means normal operation. An off LED means the module has no power. A flashing LED signals a fault inside the module. The module is solid-state and installs into an I/O Terminal Block.

Moreover, up to eight Field Control modules of any type can connect to one BIU. These eight modules plus the BIU form a Field Control station. This station equals a modular PLC system in function. The compact design saves panel space and simplifies wiring.

Installation Guide

First, insert the IC670ALG620 into an I/O Terminal Block. Next, connect the terminal block to the main Bus Interface Unit. Then, wire the RTD sensors to the input channels. Use 3-wire or 4-wire connections as needed. After that, attach the handheld programmer to the BIU. Finally, configure each channel through the programmer.

Besides, keep lead resistance below 5 ohms per lead. Check the LED after power-up. A steady light confirms normal operation. If the LED flashes, inspect the module for faults. If the LED stays off, verify BIU power and terminal block seating. For unused channels, set them as inactive in the configuration.
