The GE Fanuc IC694ALG221A is a high-performance 4-channel differential analog current input module for the PACSystems™ RX3i platform. The IC694ALG221A converts 4‑20 mA or 0‑20 mA signals from field transmitters into 12‑bit digital data for the PLC CPU. With a 2 ms update rate, optical isolation, and jumper-selectable ranges per channel pair, the IC694ALG221A delivers reliable, high-accuracy signal acquisition for demanding process control applications.
Pressure, temperature, and flow monitoring – pressure transmitters, temperature sensors, flow meters
Oil and gas refineries – flow and pressure monitoring in distillation and pipeline systems
Power generation – generator parameters and transformer oil temperature monitoring
Chemical and petrochemical plants – reactor temperature and pressure control loops
Water and wastewater treatment – flow rate and level monitoring
Steel and metal processing – furnace temperature profiling and equipment monitoring
Pharmaceutical manufacturing – batch process monitoring and validation
Four differential current inputs – independently configurable 4–20 mA or 0–20 mA via two onboard jumpers (one per channel pair)
12‑bit resolution – 4 µA/count at 4–20 mA; 5 µA/count at 0–20 mA for fine measurement granularity
High update rate – 2 ms for all four channels with 0.5 ms conversion per channel
Optical isolation – 250 V AC continuous / 1500 V AC for 1 minute between field wiring and backplane
High common‑mode voltage tolerance – withstands up to 200 V with reduced performance
Factory calibrated – no field trim pots required; 4 µA per count calibration
Hot‑swappable – supports online replacement without system shutdown
Wide agency approvals – UL, UL HAZLOC, Zone 2 CE, ATEX C1D2, ABS, BV, DNV, GL, KRS, LR
Compact single‑slot design – installs in any I/O slot of the RX3i backplane
Converts 4–20 mA or 0–20 mA analog signals – digitizes field transmitter outputs into 12‑bit binary data for the PLC CPU
Provides high‑accuracy current measurement – 0.1% full scale + 0.1% reading precision
Optically isolates field wiring from backplane – protects the PLC from electrical noise and transient voltages
Supports differential inputs – rejects common‑mode noise for reliable signal acquisition in electrically noisy environments
Delivers rapid channel updates – 2 ms refresh rate for real‑time process monitoring and control
Q1: What is the difference between IC694ALG221 and IC694ALG221A?
A1: The IC694ALG221A is Revision A of the same hardware. It is a direct replacement for the base IC694ALG221 with identical functionality and no configuration changes required.
Q2: Does the IC694ALG221A support hot‑swapping?
A2: Yes. The IC694ALG221A supports hot‑swap, allowing module replacement without system shutdown.
Q3: How do I change the input range on the IC694ALG221A?
A3: Two onboard jumpers control the input range: one for channels 1 and 2, and another for channels 3 and 4. Installing a jumper changes the range from 4–20 mA (default) to 0–20 mA.
Q4: What power supply does the IC694ALG221A require?
A4: The IC694ALG221A draws 25 mA from the +5 V DC backplane and 100 mA from an isolated +24 V DC supply (required when installed in a Universal Backplane).
Q5: What is the accuracy of the IC694ALG221A?
A5: The IC694ALG221A provides absolute accuracy of 0.1% of full scale plus 0.1% of reading. In the presence of severe RF interference, accuracy may degrade to ±0.5% FS.
