The GE IC695ALG508 is a high-performance analog input module designed for GE’s PACSystems RX3i programmable automation controllers, serving as a critical component in industrial automation systems across manufacturing, energy, and process industries. As part of the IC695 Series, this module specializes in converting continuous physical signals—such as pressure, temperature, and flow—from field sensors into digital data that the RX3i controller can process, enabling precise real-time monitoring and closed-loop control.
Featuring 16 differential analog input channels, the GE IC695ALG508 supports a wide range of input types, including 4–20 mA, 0–20 mA, 0–10 V DC, and ±10 V DC, making it compatible with diverse industrial sensors. Its 16-bit resolution and ±0.1% full-scale accuracy (at 25°C) ensure precise signal conversion, critical for applications like turbine speed regulation or chemical reactor temperature control. The module’s 2500 Vrms galvanic isolation between channels and backplane protects the RX3i controller from voltage spikes and electromagnetic interference (EMI), ensuring signal integrity in electrically noisy environments.
In automation systems, the IC695ALG508 integrates seamlessly with the RX3i backplane, communicating via the controller’s high-speed bus to minimize latency. Its compact design (fitting within standard RX3i racks) maximizes space efficiency, while onboard diagnostics—including open-circuit detection and overrange alerts—enable proactive fault resolution. By combining high channel density, flexibility, and reliability, the GE IC695ALG508 enhances system performance, reduces wiring complexity, and simplifies scalability in industrial settings where precision and uptime are paramount.

High channel density:
With 16 differential channels in a compact form factor, the module maximizes rack space efficiency, ideal for large-scale systems requiring multiple sensor inputs. For example, in an automotive paint shop, it can simultaneously monitor temperature, pressure, and flow rates across 16 spray booths, reducing the number of modules needed and lowering overall system costs.

Flexible input compatibility:
Support for multiple input types (4–20 mA, 0–20 mA, 0–10 V DC, ±10 V DC) adapts to diverse sensors—from pressure transducers in water treatment plants to thermocouple amplifiers in steel mills. This flexibility eliminates the need for specialized modules, simplifying inventory management and reducing installation complexity.

Robust galvanic isolation:
2500 Vrms isolation between channels and the backplane protects the RX3i controller from ground loops, voltage transients, and EMI—common in facilities with high-voltage machinery. This isolation ensures signal integrity in environments with welders, motor drives, or variable frequency drives, preventing erroneous control actions.

Rapid update rates:
A 2 ms per channel update rate ensures real-time data acquisition, enabling the RX3i controller to respond quickly to dynamic process changes. In energy production, this speed allows immediate adjustments to turbine fuel flow based on incoming pressure readings, optimizing efficiency and grid stability.
