Product Overview
The GE IC695ALG628 is a high-precision analog output module designed for GE’s PACSystems™ RX3i and RX7i programmable automation controllers (PACs), specializing in converting digital control signals from the PAC into precise analog outputs to regulate industrial devices. Its core function is to deliver accurate 4-20mA current and 0-10V voltage signals, enabling precise control of valves, variable frequency drives (VFDs), heaters, and other analog actuators critical to process and manufacturing operations.
As a key component in GE’s analog control ecosystem, the GE IC695ALG628 stands out for its 8-channel design, balancing density and flexibility to support multiple control points within a single rack slot. Its high resolution and low drift ensure consistent performance over time, even in temperature-fluctuating environments—vital for applications where precision directly impacts product quality or process efficiency. What distinguishes the GE IC695ALG628 is its robust channel isolation and integrated protection features, making it reliable in electrically noisy industrial settings. This combination of accuracy, versatility, and durability positions it as an essential tool for closed-loop control systems.

Key Features and Benefits
The GE IC695ALG628 delivers exceptional precision with 16-bit resolution and ±0.05% accuracy, ensuring that even 细微 adjustments to analog outputs—such as fine-tuning valve positions in chemical dosing systems—are executed with pinpoint accuracy. This level of control is critical for maintaining process stability and product consistency in industries like pharmaceuticals and semiconductor manufacturing.
Each of its 8 channels features robust isolation (500V AC channel-to-channel), minimizing interference from electrical noise generated by nearby motors or drives. This isolation ensures that outputs remain stable even in harsh industrial environments, reducing the risk of erroneous control signals that could disrupt operations.
The module supports a wide range of output signals, from 4-20mA current loops (ideal for long-distance valve control) to 0-10V voltage signals (common for VFDs and heaters). This versatility eliminates the need for external signal converters, simplifying system design and lowering integration costs.
Integrated protection mechanisms, including overcurrent and short-circuit safeguards, prevent damage to the module and connected devices. In the event of a fault, the GE IC695ALG628 automatically limits current and recovers once the issue is resolved, minimizing downtime. Diagnostic features, such as output status monitoring via PAC software, enable quick identification of wiring or device faults.
Application Scenarios
The GE IC695ALG628 is widely used in chemical processing plants, where RX7i PACs rely on it to control motorized valves regulating the flow of raw materials into reactors. By converting the PAC’s digital setpoints into precise 4-20mA signals, it ensures accurate flow rates, directly impacting reaction yields and reducing waste.
In automotive manufacturing, the GE IC695ALG628 controls variable frequency drives (VFDs) for conveyor systems and hydraulic proportional valves in robotic assembly cells. Its fast update rate (1ms per channel) enables real-time adjustments to conveyor speed and valve pressure, ensuring smooth part transfer and precise component fitting.
Water treatment facilities utilize the GE IC695ALG628 to regulate chemical dosing pumps (via 4-20mA signals) and adjust the opening of sludge valves (via 0-10V signals). This allows the RX3i PAC to maintain optimal pH levels and sludge removal rates, ensuring compliance with environmental regulations.
In food and beverage processing, the module controls temperature in pasteurization tanks and pressure in filling machines, where its accuracy prevents under/over-pasteurization and ensures consistent fill volumes.

Installation and Maintenance
Installation of the GE IC695ALG628 requires an available 1-slot position in RX3i or RX7i racks, with the system powered down during insertion. Use shielded twisted-pair cables for all connections, grounding the shields at both the module and device ends to minimize electromagnetic interference. Ensure the mounting rack is properly grounded to maintain isolation integrity, and install the module in a cabinet with ambient temperatures between 0°C and 60°C.
For maintenance, calibrate the GE IC695ALG628 annually using a precision calibrator to verify output accuracy within ±0.05% of full scale. Inspect terminal connections quarterly for tightness and corrosion, especially in humid environments. Clean dust from vents with compressed air to prevent overheating. Replace the module every 6-8 years as preventive maintenance, or immediately if outputs consistently drift beyond calibration limits.
