Description

GE IC693ALG442 Analog Current/Voltage Combination Module

Product Overview

The GE IC693ALG442 is a 4-channel analog input/2-channel analog output module designed for GE Fanuc’s Series 90-30 PLC platform, now under Emerson Automation Solutions. As part of the IC693 Series, this module bridges digital PLC logic with analog field devices, enabling precise data acquisition and control in industrial automation systems. With support for voltage (0–10 V, –10–+10 V) and current (0–20 mA, 4–20 mA) signals, the IC693ALG442 is ideal for hybrid systems requiring both measurement and actuation capabilities, such as turbine control, process monitoring, and machinery automation 47.

Featuring 12-bit resolution (5 µA per bit for current inputs; 2.5 mV/5 mV for voltage inputs), the IC693ALG442 delivers ±0.25% accuracy at 25°C for inputs and ±0.1% accuracy at 25°C for outputs, ensuring reliable performance in critical applications . Its 8 ms input update rate and 4 ms output update rate support real-time responsiveness, while 1,500 V RMS isolation between field and logic sides mitigates electromagnetic interference (EMI) in high-noise environments like manufacturing plants or oil refineries . The module incorporates MOV (Metal Oxide Varistor) surge protection on high-power terminals, safeguarding against voltage spikes caused by inductive loads or transient electrical noise .

In automation systems, the IC693ALG442 integrates with Series 90-30 CPUs (e.g., IC693CPU340, IC693CPU364) and Genius Bus Interface Units (BIUs) to provide bidirectional analog communication. Its compact DIN rail-mount design (125 mm × 48 mm × 45 mm) and lightweight construction (0.35 kg) simplify installation in crowded control panels, while a flame-retardant ABS housing ensures durability in temperatures ranging from 0°C to 60°C and 95% non-condensing humidity . Though discontinued by GE, the IC693ALG442 remains critical for legacy systems, offering cost-effective scalability where upgrading to newer platforms is impractical. By combining high-resolution signal conditioning, rugged isolation, and deep integration with Series 90-30 components, this module enhances system precision and reduces downtime in mission-critical operations.

Technical Specifications

Main Features and Advantages

Hybrid analog capabilities:
The IC693ALG442 supports both voltage and current inputs/outputs, eliminating the need for separate modules in mixed-signal systems. For example, it can simultaneously acquire temperature data from 4–20 mA RTD sensors and control valve positions via 0–10 V signals in chemical processing plants .

High-resolution bidirectional communication:
With 12-bit resolution and 5 µA/bit precision, the module ensures fine-grained control over actuators while maintaining accurate measurement of analog signals. Its ±0.1% output accuracy guarantees repeatable performance in applications like semiconductor wafer handling, where minor deviations could impact product quality .

Rugged industrial design:
The flame-retardant ABS housing and MOV surge protection shield the module from electrical transients and environmental hazards, making it suitable for harsh settings like offshore platforms or food processing plants. Its 1,500 V RMS isolation further mitigates EMI from nearby motors or drives, ensuring stable operation in high-noise environments .

Software-configurable flexibility:
The IC693ALG442 is configured via LogicMaster 90-30 or Cimplicity Control Configurator software, allowing users to select input/output ranges, filter settings, and channel modes (voltage/current) without hardware modifications. A jumper switch is required for current input mode selection, streamlining setup for mixed-signal applications .

Application Areas

The GE IC693ALG442 excels in industries requiring bidirectional analog control:

• Power Generation:
  Monitors turbine vibration (4–20 mA) and adjusts steam valve positions (0–10 V) in power plants, enabling condition-based maintenance and grid demand responsiveness 2.
• Oil and Gas:
  Regulates flow rates in wellhead control systems (0–20 mA) while acquiring pressure data from transducers (–10–+10 V), integrating with motorized actuators in refineries .
• Manufacturing:
  Controls conveyor belt speeds (0–10 V) and monitors quality metrics (4–20 mA) in automotive assembly lines, ensuring synchronization with upstream/downstream processes .
• Water Treatment:
  Manages chemical dosing pumps (4–20 mA) based on pH sensor inputs (0–10 V), ensuring compliance with environmental regulations in wastewater treatment plants .

Installation and Maintenance

Pre-installation preparations:
Verify compatibility with the target Series 90-30 CPU (e.g., IC693CPU340) and power supply (e.g., IC693PWR330). Mount the IC693ALG442 on a clean, grounded DIN rail or panel using #8-32 screws, ensuring the 20-terminal block aligns with the module’s faceplate. Route shielded twisted-pair cables away from high-voltage lines to minimize EMI, grounding the shield at the field device end for single-ended inputs. Configure the module via software to select the desired input/output ranges and enable hold-last-state functionality if required .

Maintenance suggestions:
Perform quarterly visual inspections to check for loose connections or physical damage, retightening terminals to 5 lb-in torque as needed. Test surge protection components annually using a multimeter to ensure MOVs are functional. Replace the module every 7–10 years (or sooner if physical damage is detected) to maintain signal integrity. Store spare IC693ALG442 modules in anti-static packaging at 10–30°C with <60% humidity, testing functionality biannually .
