Product Overview

The IC695ALG628 GE Fanuc / Emerson Automation PACSystem RX3i Analog Input Module delivers high-precision 24-bit resolution measurement across eight single-ended or four differential channels. Equipped with integrated HART Version 5.0 protocol support and dual internal modems, this advanced module seamlessly bridges complex process instrumentation with high-performance control backplanes.

Configuration and Technical Parameters

Installation and Wiring Guidelines

Mount the IC695ALG628 module directly into the universal backplane of an RX3i system. Terminate field wiring using box-style (IC694TBB032), extended box-style (IC694TBB132), spring-style (IC694TBS032), or extended spring-style (IC694TBS132) terminal blocks. Utilize extended terminal blocks when employing shielded cables to gain necessary shroud depth and noise immunity.

Debugging and Maintenance Convenience

Global PLC Spare HUB's Insight: Built-in autocalibration executes automatically upon every power-up cycle to maintain measurement accuracy. Software-configurable alarm thresholds (High, Low, High-High, Low-Low, and Rate of Change) allow engineers to catch sensor degradation early without physical jumper modifications.

Compatibility and Environmental Standards

Fully compatible with Machine Edition version 5.0 SP3 and later programming environments, this module operates reliably from 32°F to 140°F (0°C to 60°C) under 5% to 95% non-condensing humidity. Flash memory architecture supports straightforward firmware upgrades for long-term system maintainability.

Package Contents, Warranty, and Logistics

The shipment includes the IC695ALG628 analog input module (terminal blocks sold separately). Global PLC Spare HUB backs this precision instrument with a dependable 12-month warranty. All orders dispatch swiftly within 24 to 48 hours via premium global logistics partners including FedEx, UPS, and DHL.

Target Applications and Diagnostic Capabilities

• Precision chemical dosing flow rate tracking via 4-20mA HART transmitters
• Refinery pressure transmitter diagnostics and remote device configuration
• Power generation temperature and multi-variable sensor data acquisition
• Water treatment facility level monitoring with open-circuit fault detection

Selection Guide and Engineering Advice

When engineering HART loops, configure channel current ranges explicitly to 4-20 mA to ensure proper digital signal overlay. Verify that total backplane current consumption does not exceed power supply limits, particularly when combining high-draw HART modules on a single RX3i rack.

Frequently Asked Questions

Q: Why does the module require extended terminal blocks like the IC694TBB132 in heavy industrial skids?
A: Extended terminal blocks provide extra shroud depth required to properly terminate bulky braided shielding wires, preventing ground loops and electromagnetic interference.

Q: How do internal HART modems manage data polling across eight single-ended channels?
A: The module utilizes two internal HART modems multiplexed across active channels to poll digital process variables without interrupting core analog scan cycles.

Q: What triggers a 1-second maximum open circuit detection alert on current inputs?
A: If loop continuity breaks or transmitter power fails, dropping current below operational thresholds, the module flags an open-circuit fault within 1 second.

Q: Can the 24-bit resolution data format be changed dynamically via control logic?
A: Yes, output data format is fully software configurable, allowing selection between IEEE 32-bit floating point or 16-bit integer values packed inside a 32-bit register.

Q: What preventive steps minimize signal fluctuation on long analog input wire runs?
A: Operators should select appropriate configurable input filter settings (ranging from 8 Hz to 500 Hz) to smooth out high-frequency plant electrical noise.
