IC670ALG630 GE Fanuc 8-Channel T/C Input Module

IC670ALG630 GE Fanuc Thermocouple Input Module

Product Introduction

The IC670ALG630 is an 8-channel thermocouple input module from GE Fanuc. It belongs to the Field Control series. This microprocessor-based unit receives signals from eight isolated inputs. Then it converts those signals into digital form. The bus interface module handles the complete I/O data exchange. At each power-up, the module runs A/D calibration on itself automatically.

Moreover, the IC670ALG630 uses the word data type. It provides 8 words of analog input data and 8 words of analog output data. Users can configure each thermocouple input individually. Specifically, each channel can report readings as temperature or as millivolts.

Technical Specifications

The IC670ALG630 supports many thermocouple types. These include J, K, T, E, S, R, B, N, G, C, D, and Platinel II. Converter resolution reaches 15 bits plus sign. Available spans are ±19.5 mV, ±39 mV, ±78.125 mV, ±156.25 mV, ±312.5 mV, and ±625 mV.

Additionally, temperature sensitivity from 0 to 60 °C is ±0.004% of reading plus ±1.5 mV per °C referred to input. Maximum voltage between channels is 250 VAC. The module draws 195 mA maximum from the BIU power supply. It needs no external power source. An optically-coupled multiplexer extracts analog readings and sends them to the A/D converter. The converter then turns the analog voltage into a binary value.

Mechanical and Environmental Parameters

The IC670ALG630 has one LED indicator on the front. A steady light means proper operation. An off LED means no power reaches the module. A blinking LED signals a system fault. The operating temperature range is 0 °C to 55 °C. The module comes with an open construction. Therefore, install it inside a protective enclosure rated IP 20.

Furthermore, the unit offers two data acquisition rates. It also provides configurable high/low alarm levels and millivolt ranges. The module performs many diagnostics. It detects open thermocouple, over/under range, and high/low alarm faults. These diagnostics go to the bus interface unit for quick error detection.

Installation Guide

First, mount the IC670ALG630 onto an I/O terminal block. Next, wire the thermocouple sensors directly to the terminal block. Then, connect the terminal block to the Bus Interface Unit. After that, use a proprietary handheld programmer to set reference parameters. Finally, store the configuration in the BIU.

Besides, keep the module away from strong heat or cold sources. Since it has an IP 20 rating, protect it from dust and water. Up to eight IC670ALG630 modules can link to one BIU. This setup processes up to 64 independent thermocouple signals in a single control system. Check the LED after power-up to confirm normal status.
