GE IC693ALG220 Series 90-30 4-Channel Analog Voltage Input Module
Product Overview
The GE IC693ALG220 is a high-precision 4-channel analog voltage input module designed for GE Fanuc’s Series 90-30 PLC system, serving as a critical interface for converting analog signals into digital data in industrial automation applications. With support for -10 to +10V DC input ranges and configurable current mode (via internal 250Ω shunt resistors for -40 to +40mA signals) 15, the IC693ALG220 enables precise monitoring of process variables such as temperature, pressure, and flow in manufacturing, energy, and water treatment systems.
As part of the Series 90-30 platform, the GE IC693ALG220 integrates seamlessly with controllers like IC693CPU374 and power supplies such as IC693PWR330, forming a robust automation ecosystem. Its 12-bit resolution (1 part in 4,096) and 4-millisecond update rate ensure rapid and accurate data conversion, while 1,500V AC isolation between field inputs and logic circuits safeguards against electrical noise and ground loops 39. The module’s factory-calibrated design minimizes drift, reducing maintenance efforts in critical environments like chemical plants or power generation facilities.
The IC693ALG220 operates on 24V DC power from the PLC backplane, consuming 27mA from the +5V bus and 98mA from the +24V bus . Its compact form factor (110mm × 64mm × 30mm) and lightweight construction (0.3kg) facilitate easy installation in space-constrained control cabinets, while the IP20-rated housing protects against dust and accidental contact . LED indicators on the front panel provide real-time status feedback, including power supply and channel activity, simplifying troubleshooting in complex systems.

Main Features and Advantages
High-Precision Signal Conversion
The IC693ALG220’s 12-bit ADC delivers 5mV resolution for voltage inputs, ensuring accurate representation of subtle process variations. This precision is critical in applications like pharmaceutical batch processing, where tight control over temperature or pressure is essential for product quality.
Flexible Signal Configuration
With jumper-selectable voltage or current modes, the module adapts to diverse sensor types without hardware modifications. For example, it can directly interface with 4-20mA flow meters by activating the internal shunt resistor, eliminating the need for external signal conditioning .
Robust Noise Immunity
1,500V AC isolation and optical coupling protect against electromagnetic interference (EMI) from motors, welders, or radio frequency sources. This is particularly valuable in automotive manufacturing plants, where high-power equipment often generates significant electrical noise.
Diagnostic Capabilities
Front-panel LED indicators for power (PWR) and channel status (OK) provide immediate visual feedback. For instance, a flickering OK LED may indicate a loose connection or sensor malfunction, enabling rapid corrective action 6.
Easy Integration and Maintenance
The IC693ALG220 mounts directly onto DIN rails in Series 90-30 racks, requiring minimal setup time. Its hot-swap capability allows replacement without powering down the system, reducing downtime during maintenance—a key advantage in 24/7 operations like wastewater treatment plants .
