GE IC695ALG728 Analog Input Module
Product Overview
The GE IC695ALG728 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, acting as a critical link between field devices and the control system. It enables precise monitoring of continuous variables, making it essential for maintaining stable and efficient industrial processes.
As part of the IC695 Series, the GE IC695ALG728 integrates seamlessly with RX3i backplanes like the IC694CHS790 and works with 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 IC695ALG728 supports a range of input signals, including 4–20 mA, 0–10 V DC, and RTDs (Pt100), making it compatible with common industrial sensors used in temperature and pressure monitoring.
Built to withstand harsh conditions, the GE IC695ALG728 operates in temperatures from -20°C to 60°C and humidity up to 95% (non-condensing). It features channel-to-channel isolation (250 V AC) to resist electrical noise and ground loops, ensuring accurate data even near large motors or high-voltage equipment. Though it is a legacy model, the GE IC695ALG728 remains vital for older RX3i systems, helping businesses avoid full upgrades while keeping their monitoring systems reliable.

Main features and advantages
8-channel monitoring capability: The IC695ALG728 offers 8 input channels, allowing it to monitor 8 separate sensors simultaneously—such as 8 pressure transducers in a hydraulic system. This reduces the number of modules needed in a system, saving space in the backplane rack and simplifying wiring.
Wide signal compatibility: The module supports 4–20 mA, 0–10 V DC, and Pt100 RTDs, making it compatible with common industrial sensors. This versatility means it can connect to flow meters, temperature probes, and pressure sensors without needing external signal converters, cutting hardware costs.
High precision: With 16-bit resolution and ±0.05% accuracy, the IC695ALG728 provides precise readings. For example, it can detect tiny temperature changes (as small as 0.01°C with Pt100s) in a pharmaceutical reactor, ensuring strict process control and product quality.
Channel isolation: 250 V AC channel-to-channel isolation prevents electrical noise from interfering with signals. This is critical in noisy environments—like factories with large motors—where interference could distort readings and cause process errors.
Rugged design: The module operates in temperatures from -20°C to 60°C and resists humidity and dust. This durability makes it suitable for cold storage facilities, outdoor installations, and chemical plants, ensuring reliable performance in harsh conditions.
Easy integration: The IC695ALG728 fits into any RX3i backplane slot without special tools. It configures quickly via GE’s Proficy Machine Edition software, allowing users to set signal types, scaling, and filtering with minimal effort. It works seamlessly with all RX3i CPUs, simplifying upgrades to existing systems.

Installation and maintenance
Pre-installation preparations: Check that the IC695ALG728 is compatible with your RX3i backplane (e.g., IC694CHS790) and CPU (e.g., IC694CPU331). Ensure there is an empty I/O slot. Power off the system and disconnect all power sources. Align the module with the slot and push firmly until it clicks into place. Connect sensor wires to the terminal block, matching each sensor to a channel and following polarity guidelines. Use shielded cables and ground the shield to reduce electrical noise. Power on the system and verify the module’s green LED is lit, indicating normal operation.
Maintenance suggestions: Inspect the IC695ALG728 monthly. Wipe dust from the module’s surface with a dry cloth to prevent overheating. Check wire connections to ensure they are tight—loose connections can cause inaccurate readings. If a channel shows erratic data, test the connected sensor first; if the sensor works, power off the system, remove the module, and reinsert it to fix potential loose backplane connections. Store a spare IC695ALG728 in a dry, cool area (10–30°C) to enable quick replacement if needed, minimizing downtime.
Application fields
The GE IC695ALG728 is widely used in industries requiring precise analog monitoring:
