IC695ALG628 RX3i 8-Channel Analog Input GE

IC695ALG628 GE Fanuc Analog Input Module with HART

Product Introduction

The IC695ALG628 analog input module belongs to the PACSystem RX3i platform. Emerson Automation now owns this product line, formerly manufactured by GE Intelligent Platforms. This module stands out because it supports HART version 5.0 communication on all channels. It accepts either eight single-ended inputs or four differential inputs.

Specifically, the IC695ALG628 handles multiple voltage and current ranges. Voltage inputs include ±10V, 0-10V, ±5V, 0-5V, and 1-5V. Current inputs include 0-20 mA, 4-20 mA, and ±20 mA. The module includes two internal HART modems. This allows direct communication with smart field devices for diagnostics and configuration.

HART Communication Features

The IC695ALG628 excels in HART-enabled applications. Two internal HART modems serve all channels. HART version 5.0 is supported on every input. For HART communication, configure the current range to 4-20 mA.

This module allows users to read primary variables and additional HART data. Engineers can access device status, diagnostics, and configuration parameters directly through the PLC. This reduces the need for separate handheld communicators.

Configuration & Alarms

The IC695ALG628 is fully software configurable without any jumpers. Each channel can have independent alarm settings. These include high alarm, low alarm, high-high alarm, and low-low alarm. Additionally, positive and negative rate of change alarms are available.

Configurable interrupts for channel alarms and faults can be set accordingly. The module also supports terminal block insertion and removal detection. Error reporting is built-in and comprehensive.

Mechanical & Environmental Parameters

• Slot Requirement: 1 slot on RX3i universal backplane

• Weight: Approximately 0.38 kg

• Operating Temperature: 0°C to 60°C (32°F to 140°F)

• Storage Temperature: -40°C to 85°C (-40°F to 185°F)

• Humidity: 5% to 95%, non-condensing

• Compatible Terminal Blocks: IC694TBB032 (box-style), IC694TBB132 (extended box), IC694TBS032 (spring-style), IC694TBS132 (extended spring)

• Extended Terminal Blocks: Provide additional shroud depth for shielded wiring

Installation Guidelines

Installing the IC695ALG628 requires careful planning for HART wiring. First, power down the RX3i backplane completely. Insert the module into any slot on the universal backplane. Select the appropriate terminal block. Extended terminal blocks are recommended for shielded wiring applications.

Next, wire each channel according to single-ended or differential configuration. For HART communication, always use 4-20 mA current loops. Ensure a minimum load resistance of 250 Ω for proper HART modem operation. After wiring, configure the module through Proficy Machine Edition version 5.0 SP3 or later.

The IC695ALG628 performs autocalibration at every power-up. This ensures consistent accuracy without manual intervention. Only qualified personnel should install this module.

Frequently Asked Questions (FAQ)

1. What is the difference between single-ended and differential wiring on the IC695ALG628?
Single-ended mode gives you 8 channels but shares a common ground. Differential mode gives you 4 channels but provides better noise immunity for long cable runs.

2. Does every channel on the IC695ALG628 support HART communication?
Yes. However, the module has two internal HART modems that are shared across all channels. For HART operation, use the 4-20 mA current range.

3. What software version is required to program the IC695ALG628?
You need Proficy Machine Edition version 5.0 SP3 or later.

4. What filter options are available on this module?
The IC695ALG628 offers six configurable filters: 8 Hz, 12 Hz, 16 Hz, 40 Hz, 200 Hz, and 500 Hz. Lower filters provide more noise rejection but slower response.

5. Does the IC695ALG628 perform automatic calibration?
Yes. Autocalibration runs during every power-up cycle. This eliminates manual calibration and maintains accuracy over time.
