GE IC694ALG222 Analog Input Module
Product Introduction
The GE IC694ALG222 is a high-density analog input module designed for the Series 90-30 and RX3i PLC platforms. It provides four isolated input channels with 12-bit resolution (up to 14-bit enhanced), configurable for voltage (±10 V, ±5 V, 0–10 V) or current (0–20 mA, 4–20 mA) signals. The module mounts on a standard 34 mm DIN-rail profile and communicates over the high-speed backplane, delivering deterministic data to the PLC for real-time process monitoring and control.
Key Applications
Monitoring pressure, temperature, and level transducers in oil & gas and petrochemical refineries.
Collecting flowmeter signals and batch process control data in chemical manufacturing.
Measuring analog outputs from precision scales and feeders in food & beverage lines.
Reading vibration and condition-monitoring sensors in power generation turbines.
Integrating environmental sensors (humidity, CO₂, pH) in water/wastewater treatment facilities.
Brand Overview
GE Automation & Controls, a division of General Electric, has over 40 years of experience delivering rugged PLC, RTU, and I/O solutions for critical industrial applications. Known for its Series 90-30, RX3i, and PACSystems platforms, GE supports global process and discrete industries with long-lifecycle hardware and comprehensive engineering services.
Product Advantages
-
Channel Isolation: Each of the four inputs is galvanically isolated to 1500 V AC, eliminating ground-loop errors.
-
Signal Flexibility: Auto-ranging and software-selectable input types reduce surplus inventory and simplify commissioning.
-
Enhanced Resolution: Supports 14-bit enhanced mode for improved measurement accuracy in fine-control loops.
-
High Throughput: Samples all channels in <10 ms, ensuring up-to-date data for fast process changes.
-
Robust Design: Operates reliably from –25 °C to +70 °C with conformal-coated PCBs for harsh environments.

Frequently Asked Questions (FAQ)
Q: What analog ranges does the IC694ALG222 support?
A: Each channel can be set to ±10 V, ±5 V, 0–10 V, 0–20 mA, or 4–20 mA via software configuration.
Q: How precise are the measurements?
A: Native 12-bit resolution yields ±0.1 % FS accuracy; enhanced mode offers up to 14-bit for finer granularity.
Q: Is channel-to-channel isolation provided?
A: Yes, each input is isolated to 1500 V AC from the backplane and from other channels.
Q: How quickly does it sample all channels?
A: All four channels are updated in under 10 ms, ensuring prompt data for fast control loops.
Q: What environmental conditions can it handle?
A: It operates in –25 °C to +70 °C and up to 95 % RH (non-condensing), with conformal coating for corrosion resistance.
Q: Which PLC platforms is it compatible with?
A: It fits Series 90-30 and RX3i backplanes, and can be used in PACSystems where slot-compatible.
