GE Fanuc IC670ALG230 Analog Input Module

IC670ALG230 Field Control 8-Point Input

Product Introduction

The IC670ALG230 analog input module belongs to the GE Fanuc Field Control series. This unit provides eight single-ended input channels for industrial signal acquisition. Each channel accepts 0-20 mA or 4-20 mA current signals. Furthermore, the module delivers 12-bit digital resolution and 5.0 µA analog resolution. It works with a compatible Bus Interface Unit (BIU) for data exchange. The IC670ALG230 suits field transmitters, panel meters, data loggers, and variable frequency drives. Additionally, it includes open wire detection and over-range fault detection for reliable operation.

Technical Specifications

The IC670ALG230 module uses a 24 VDC nominal supply voltage. Its external power range spans 18-30 VDC for flexible installation. The unit draws 100 milliamps from the BIU, with a maximum of 51 mA from BIU power. Moreover, current consumption reaches 210 mA when including the loop. Input impedance measures 2.87 kiloohms across the module. The conversion time is 60 microseconds per channel at a 1 MHz clock. Meanwhile, the digital resolution is 12 bits, typical. Non-linearity stays within +/– 0.025% of full scale. Maximum error at 25 degrees Celsius is +/– 0.05% full scale.

Isolation and Protection Features

The IC670ALG230 provides ground-to-logic isolation rated 1500 VAC for 1 minute. It also supports 250 VAC continuous isolation to case. Each channel shares a single input group with single-ended wiring. However, no isolation exists between individual points within a group. The module includes a first-order RC input filter with a 160 Hz transition capacity. Temperature coefficients are +/– 0.002% typical and +/– 0.005% maximum per degree Celsius. These features protect the module from electrical noise and signal interference.

Mechanical and Environmental Parameters

The IC670ALG230 uses an open enclosure design, so it is not waterproof. Therefore, keep it away from water sprays and excessive moisture. It operates between 0 and 60 degrees Celsius. Humidity should stay at 95% maximum, non-condensing. The module mounts with a DIN rail base for secure installation. Front LED indicators show backplane and field power status. Proper grounding reduces noise and improves signal reference stability.

Installation Guide

First, mount the IC670ALG230 module onto a grounded DIN rail base. Next, connect the 24 VDC power supply to the unit and the BIU. Then, wire the eight input channels using single-ended configuration. After that, verify that loop-powered transmitters share the same power supply. Subsequently, check the LED indicators for backplane and field power. Finally, confirm grounding to reduce noise and protect signal commons. For instance, use a separate supply when isolation is required.
