IC695ALG708 GE Analog Output Module 8 Ch

IC695ALG708 GE Fanuc Non-Isolated Analog Output Module

Product Introduction

The IC695ALG708 analog output module belongs to the PACSystem RX3i platform. Emerson Automation now manages this product line, formerly manufactured by GE Intelligent Platforms. This module provides eight non-isolated output channels. Each channel is software configurable for current or voltage signals.

Specifically, the IC695ALG708 supports 0-20 mA and 4-20 mA current loops. It also handles ±10 VDC and 0-10 VDC voltage outputs. This module works well for cost-sensitive applications where channel-to-channel isolation is not required. Engineers commonly use it to control variable frequency drives, control valves, and actuators.

Configuration & Features

The IC695ALG708 offers extensive software configurability. Users can set individual alarm parameters for each channel. These include very low, low, high, and very high alarms. Each output can also be clamped at specific high and low points. This clamping feature proves especially useful when a channel links to a PID controller output.

Additionally, output biases may be added to fine-tune the signal. This allows manual adjustment to reach the desired process level. The IC695ALG708 also includes built-in module fault reporting. Users can configure hold-last-state or output default settings for fault conditions.

For CPU compatibility, any RX3i CPU works with this module. However, the CPU must have firmware version 3.5 or later. Furthermore, you must use Proficy Machine Edition Version 5.0 SP3 Logic Developer or newer to program the module.

Mechanical & Environmental Parameters

• Slot Requirement: 1 slot on RX3i universal backplane

• Weight: Approximately 0.32 kg

• Operating Temperature: 0°C to 60°C

• Storage Temperature: -40°C to 85°C

• Humidity: 5% to 95% non-condensing

• Automatic Calibration: Supported

Installation Guidelines

Installing the IC695ALG708 requires external power and careful wiring. First, power down the RX3i backplane completely. Insert the module into any slot on the universal backplane. Then connect an external 24 VDC power supply directly to the terminal block. This external power is mandatory for the module to generate output signals.

Next, select the appropriate terminal block for your application. For instance, use spring-style blocks in high-vibration environments. After wiring each channel, configure the signal type and range through Proficy Machine Edition. Finally, power up the system and verify each output with a calibrated meter.

Only qualified personnel should handle the IC695ALG708. Always follow the installation instructions in the product manual.

Frequently Asked Questions (FAQ)

1. What is the main difference between IC695ALG708 and IC695ALG808?
The IC695ALG708 has non-isolated channels, while the IC695ALG808 provides individual channel isolation. The 708 is more cost-effective for simpler applications.

2. Does the IC695ALG708 require an external power supply?
Yes. It needs an external 24 VDC supply (19.2V to 30V range) connected directly to the terminal block.

3. What is the maximum output load for current signals?
The maximum output load is 850 Ohms for current output on the IC695ALG708.

4. Which CPU firmware version is required for this module?
You need CPU firmware version 3.5 or later. Additionally, use Proficy Machine Edition Version 5.0 SP3 or newer.

5. Can I mix voltage and current outputs on the same IC695ALG708?
Yes. Each of the eight channels is individually software configurable for either voltage or current output.
