GE IC695ALG628 Analog Input Module
Product Overview
The GE IC695ALG628 is an 8-channel analog input module designed for GE’s RX3i PACSystems, a key platform in industrial automation. This module converts real-world analog signals—such as temperature, pressure, and flow—from sensors into digital data that the PLC can process. It plays a vital role in industrial control systems, enabling precise monitoring of continuous variables critical for maintaining efficient and safe operations.
As part of the IC695 Series, the GE IC695ALG628 works seamlessly with RX3i backplanes like the IC694CHS790 and CPUs such as the IC694CPU331. It fits into any I/O slot of the backplane, drawing power through the rack and communicating with the CPU via the backplane bus. The GE IC695ALG628 supports a range of input signals, including 4–20 mA, 0–10 V DC, and thermocouples (J, K, T types), making it compatible with common industrial sensors.
Built to handle tough conditions, the GE IC695ALG628 operates in temperatures from -20°C to 60°C and humidity up to 95% (non-condensing). It features channel-to-backplane isolation (500 V AC) to resist electrical noise, ensuring accurate data even near large motors or high-voltage equipment. Though it is a legacy model, the GE IC695ALG628 remains essential for older RX3i systems, helping businesses avoid full upgrades while keeping their monitoring systems reliable.

Main features and advantages
8-channel monitoring: The IC695ALG628 offers 8 input channels, allowing it to monitor 8 separate sensors at once—such as 8 temperature probes in a chemical reactor. This reduces the number of modules needed, saving space in the backplane rack.
Wide signal support: The module works with 4–20 mA, 0–10 V DC, and common thermocouples (J, K, T). This means it can connect to most industrial sensors without extra converters, simplifying system setup and cutting costs.
High accuracy: With 16-bit resolution and ±0.1% accuracy, the IC695ALG628 provides precise readings. For example, it can detect tiny temperature changes (as small as 0.1°C) in a food processing oven, ensuring consistent product quality.
Strong isolation: 500 V AC channel-to-backplane isolation protects against electrical noise and ground loops. This keeps data reliable in noisy environments, like factories with large motors or welding machines, where interference could distort readings.
Tough design: The module operates in temperatures from -20°C to 60°C and resists humidity and dust. This makes it suitable for cold storage facilities, outdoor installations, or damp areas like water treatment plants, reducing the need for replacements.
Easy integration: The IC695ALG628 fits into any RX3i backplane slot without special tools. It works with all RX3i CPUs, so it can be added to existing systems without reconfiguring other parts. Setup is simple using GE’s software for sensor calibration.
Installation and maintenance
Pre-installation preparations: Check that the IC695ALG628 works with your RX3i backplane (e.g., IC694CHS790) and CPU (e.g., IC694CPU331). Ensure there’s an empty I/O slot. Turn off the system and disconnect power. Slide the module into the slot until it clicks. Connect sensor wires to the terminal block—match each sensor to a channel, following the wiring guide. Use shielded cables and ground the shield to reduce noise. Turn the system on and check the module’s green LED is on, meaning it’s working.
Maintenance suggestions: Inspect the IC695ALG628 monthly. Wipe dust off with a dry cloth to prevent overheating. Check wire connections to make sure they’re tight—loose wires can cause wrong readings. If a channel gives bad data, test the sensor first. If the sensor is good, turn off the system, remove the module, and reinsert it to fix loose connections. Keep a spare IC695ALG628 in a dry, cool place (10–30°C) to replace quickly if needed, minimizing downtime.
Application fields
The GE IC695ALG628 is used in industries where precise analog monitoring is key:
- Chemical processing: It monitors 8 pressure sensors in a reactor, tracking pressure changes to prevent leaks. Its accuracy ensures operators can adjust settings before dangerous pressure levels are reached.
