Description

GE IC695ALG626 Product Specification

Product Overview

The GE IC695ALG626 is a high-precision 8-channel analog input module engineered for GE’s RX3i PLC platform, designed to convert continuous physical signals (such as temperature, pressure, and flow) from field sensors into digital data for industrial automation systems. As a core component of the RX3i distributed architecture, this module enables real-time monitoring and control of critical process variables in manufacturing, power generation, oil and gas, and water/wastewater applications.

Integrated into the RX3i system, the GE IC695ALG626 supports a wide range of analog signal types, including 4–20 mA, 0–20 mA, 0–10 VDC, and thermocouples (Type J, K, T, E, R, S, B), making it versatile for diverse sensor interfaces. Its 24-bit resolution and 100 samples/second per channel sampling rate ensure high-accuracy data conversion, critical for closed-loop control in precision processes like chemical batch production or turbine efficiency optimization.

The GE IC695ALG626 features 2500 Vrms galvanic isolation between channels and from field to logic, protecting against electrical noise and surges in high-interference environments. Its compact design (115 mm × 220 mm × 125 mm) and rugged construction—including a conformal coating and IP20 enclosure—support operation in temperatures ranging from -25°C to +70°C, with resistance to vibration (10–2000 Hz, 10 G rms) and humidity (5–95% non-condensing). Front-panel LEDs provide real-time status for power, module health, and channel activity, simplifying troubleshooting, while compatibility with GE’s Proficy Machine Edition software allows easy configuration of signal scaling, filtering, and alarm thresholds. The module’s hot-swappable design minimizes downtime during maintenance, a key advantage in continuous-process industries.

Technical Specifications

Main Features and Advantages

High-Precision Signal Conversion:
The GE IC695ALG626 delivers 24-bit resolution and ±0.01% accuracy, ensuring precise measurement of subtle process variations—such as 0.1°C temperature changes in chemical reactors or 0.01 psi pressure fluctuations in pipeline systems. This level of precision is critical for optimizing efficiency in power plants, where small deviations can impact turbine performance or emissions.

Versatile signal compatibility:
Supporting multiple signal types (current, voltage, thermocouples) eliminates the need for external converters, simplifying system design. For example, the module can directly interface with 4–20 mA pressure transmitters in oil pipelines and Type K thermocouples in furnace chambers, reducing wiring complexity and potential failure points.

Rugged environmental resilience:
A conformal coating protects against dust, moisture, and chemical vapors, while the module’s wide operating temperature range (-25°C to +70°C) and vibration resistance (10–2000 Hz, 10 G rms) ensure reliability in harsh settings—from arctic oil fields to desert solar plants. ATEX/IECEx Zone 2 certification extends its use to hazardous locations like refineries.

Advanced isolation and noise immunity:
2500 Vrms isolation between channels and field/logic circuits prevents ground loops and EMI interference from motors or welders, ensuring stable data in noisy industrial environments. This isolation is vital for accurate readings in steel mills, where electrical noise is prevalent.

Integrated diagnostics:
Front-panel LEDs (Power, Module OK, Channel Fault) provide instant status updates, while built-in self-tests monitor signal integrity, sensor faults (e.g., open thermocouple), and overrange conditions. Faults are logged with timestamps in the PLC, enabling predictive maintenance—such as replacing aging pressure sensors before they drift out of calibration.

Seamless RX3i integration:
The GE IC695ALG626 connects directly to GE IC695CPU310 (RX3i CPU) via the backplane, enabling high-speed data transfer (100 Mbps) for real-time control. Compatibility with Proficy Machine Edition software allows easy configuration of scaling, filtering (0.1–100 ms), and alarm thresholds, reducing setup time by 30% compared to legacy modules.

Hot-swappable design:
The module supports hot swapping, allowing replacement without powering down the RX3i rack. This feature cuts mean time to repair (MTTR) to under 15 minutes, critical for maintaining uptime in continuous processes like pharmaceutical manufacturing or water treatment.

Application Areas

Power Generation:

1. Monitors steam turbine inlet pressure via 4–20 mA transmitters, adjusting bypass valves to maintain optimal flow during load changes.
2. Measures generator winding temperature using Type R thermocouples, triggering cooling systems to prevent overheating and insulation damage.

Oil and Gas:

1. Processes 0–10 VDC signals from level transmitters in storage tanks, automating pump operations to prevent overflow or underflow.
2. Monitors pipeline flow rates via 4–20 mA flowmeters, adjusting compressor speeds to maintain efficient throughput

Manufacturing:

1. Regulates oven temperature in automotive paint shops using Type K thermocouples, ensuring consistent curing and finish quality.
2. Measures hydraulic pressure in robotic arms via 4–20 mA sensors, optimizing motion control for precise welding

Water/Wastewater:

1. Monitors pH levels (converted to 4–20 mA) in treatment tanks, activating chemical dosing pumps to maintain compliance with discharge standards.
2. Tracks filter pressure drop via 0–20 mA transmitters, scheduling backwashing to prevent system clogging

Renewable Energy:

1. Measures solar panel coolant temperature using Type T thermocouples, adjusting pump speeds to maximize inverter efficiency.
2. Monitors wind turbine gearbox oil pressure via 4–20 mA sensors, triggering maintenance alerts for low lubrication.
