GE Fanuc IC670ALG330 8-Point Analog Output Module

IC670ALG330 GE Fanuc Analog Current Output Module

Product Introduction

The IC670ALG330 is a Field Control series module from GE Fanuc. It provides eight single-ended analog output channels. Each channel sends a current signal from 0 to 20 mA. The module uses a 16-bit digital-to-analog converter. Its resolution reaches 0.3125 µA per count. This high precision suits demanding industrial control tasks.

Furthermore, the IC670ALG330 reports underrange, overrange, and open wire faults. It supports bit and word data types. Users can scale each channel and set output levels. The flash memory stores factory calibration data. Therefore, you can reset the module to its original settings easily.

Technical Specifications

The IC670ALG330 offers eight current-source outputs. Its nominal output signal is 0-20 mA. The full output range extends to 0.0-20.48 mA. Conversion resolution is 16 bits. Magnitude data size is 14 bits. Linearity is 1 LSB.

Additionally, the update time is 1.5 ms typical per channel. The open wire output current threshold ranges from 1.0 mA minimum to 3.5 mA maximum. Output load capacitance must not exceed 2000 pF. Output load inductance must stay below 0.5 H.

The module draws 85 mA maximum from the BIU power supply. It also draws 250 mA maximum from the external supply. This external draw occurs when all eight outputs run at 20 mA. The external power supply range is 18-30 VDC. The nominal supply voltage is 24 VDC. Maximum ripple is 10%.

Mechanical and Environmental Parameters

The IC670ALG330 has one LED indicator. A steady light means normal operation. An intermittent flash signals a fault. No light indicates power loss or a fatal error. Isolation rating is 1500 VAC for 1 minute. Continuous isolation is 250 VAC. The operating temperature range is 0-55 °C.

Moreover, the module holds last state outputs during specific events. These events include BIU reset, timeout with no output data, backplane power loss, and watchdog timer expiration. During backplane power loss and watchdog expiration, held value resolution drops from 16 bits to 14 bits.

Installation Guide

First, mount the IC670ALG330 in a Field Control rack. Next, connect the external power supply. Use a 24 VDC source within the 18-30 VDC range. Then, wire the eight output channels. Keep single-ended wiring configuration. After that, attach the Bus Interface Unit (BIU). Finally, configure scaling parameters through your control software.

Besides, verify load capacitance and inductance limits. Do not exceed 2000 pF or 0.5 H. Check the LED for normal status. A steady light confirms proper operation. If the LED flashes, inspect wiring and power. If no light appears, check backplane power and watchdog status.
