GE IC695ALG808-AA

Product Introduction

The GE IC695ALG808-AA is a high-density analog input module in GE’s RX3i PLC family, engineered to serve as a “multi-sensor signal hub” for industrial automation systems. Unlike low-channel analog modules, the GE IC695ALG808-AA packs 8 independently configurable differential channels into a compact form factor—making it ideal for applications where space is limited but multiple analog signals (e.g., temperature, pressure, flow) need to be acquired.

Technical positioning for mid-to-large-scale projects (e.g., chemical plants, renewable energy facilities), the GE IC695ALG808-AA converts continuous analog sensor signals into precise digital data for RX3i controllers. It supports a wide range of input types (voltage and current) without hardware reconfiguration, eliminating the need to mix multiple module models. In automation architectures, the GE IC695ALG808-AA acts as the “sensory interface,” ensuring RX3i PLCs receive reliable, high-precision data to drive critical decisions like process adjustments, safety alarms, and efficiency optimizations.

Core Advantages and Technical Highlights

8-Channel high density: The GE IC695ALG808-AA’s 8 differential channels reduce control cabinet footprint by up to 50% compared to using two 4-channel modules. For example, a solar power plant monitoring 8 inverter temperature sensors can use one GE IC695ALG808-AA instead of two smaller modules—saving chassis slots and lowering hardware costs while simplifying wiring.

High-precision signal acquisition: With 16-bit resolution and ±0.05% full-scale accuracy at ambient temperature, the GE IC695ALG808-AA outperforms standard 14-bit analog modules. This precision is critical for applications like pharmaceutical batch processing, where it can detect 0.01V fluctuations from pH sensors—ensuring compliance with strict quality standards and reducing product waste.

Channel-by-channel configurability: Each of the GE IC695ALG808-AA’s 8 channels can be independently set to voltage or current inputs via GE’s Proficy Machine Edition software. No physical DIP switches are required, allowing technicians to reconfigure channels remotely (via Ethernet) if sensor types change—saving downtime in dynamic environments like flexible manufacturing lines.

Robust isolation and protection: The GE IC695ALG808-AA features 250V AC channel-to-channel isolation, preventing signal cross-talk and shielding against electrical noise from nearby motors or variable frequency drives (VFDs). It also includes short-circuit protection on all channels; if a sensor wire is accidentally grounded, the GE IC695ALG808-AA shuts down the affected channel without damaging the module or chassis—reducing maintenance costs and unplanned downtime.

Typical Application Scenarios

In chemical processing plants, the GE IC695ALG808-AA is central to reactor process control. It connects 8 differential 4-20mA signals from pressure transmitters (monitoring reactor vessel pressure) and RTD temperature transmitters to a IC695CPU330 RX3i PLC. The module’s ±0.05% accuracy ensures the PLC adjusts heating/cooling systems with sub-degree precision, preventing overpressure events and ensuring batch consistency. Its compact design also saves space in control cabinets crowded with other I/O modules.

For wind energy farms, the GE IC695ALG808-AA monitors key turbine parameters. It acquires 8 signals: 4 current inputs from generator speed sensors and 4 voltage inputs from oil temperature sensors. The GE IC695ALG808-AA’s differential channels reject electrical noise from turbine generators, ensuring stable data transmission to the central RX3i PLC. If a sensor fails, the module’s short-circuit protection isolates the fault, allowing the remaining 7 channels to continue operating—avoiding unnecessary turbine shutdowns.

In food and beverage processing, the GE IC695ALG808-AA supports pasteurization line monitoring. It connects 8 0-10V signals from flow meters (tracking product throughput) and 4-20mA signals from temperature sensors (monitoring heating zones) to an RX3i controller. The module’s wide operating temperature range (0°C-60°C) withstands the humid, warm environment of pasteurization facilities, while its per-channel LEDs let technicians quickly identify faulty sensors—reducing troubleshooting time from hours to minutes.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing GE IC695ALG808-AA, power off the RX3i chassis and verify the control cabinet meets environmental specs (0°C-60°C, 5%-95% non-condensing humidity). Required tools include a torque screwdriver (0.5-0.8 N·m for chassis screws), wire strippers (for 22-14 AWG sensor wires), and a multimeter (to check sensor signal integrity). Align the module with the chassis guide rails, push until it latches, and secure with front-panel screws—do not hot-swap the module, as this may damage the backplane. Connect sensor wires to the terminal block, ensuring correct polarity (e.g., + for 4-20mA signal, – for ground).

Maintenance suggestions: Daily maintenance for GE IC695ALG808-AA involves checking per-channel LEDs—steady green indicates normal operation, while red signals overrange or short circuits. Every 6 months, use compressed air (≤40 psi) to clean dust from the module’s vents and terminal block, preventing overheating or corrosion. If a channel fails, first verify the sensor and wiring (use a multimeter to test for valid 4-20mA/0-10V signals); if the issue persists, reset the module via a chassis power cycle. When replacing GE IC695ALG808-AA, ensure the new module’s firmware matches the RX3i CPU (via Proficy Machine Edition) to avoid compatibility errors.
