IC694ALG223 Functional Description   

The analog 16 point single ended IC694ALG223 General Electric is a high-density 16-channel analog input module designed for PACSystems RX3i and Series 90-30 PLC platforms. This versatile module features sixteen single-ended input channels configurable for 0-20 mA, 4-20 mA (normal), and 4-20 mA (enhanced) current signals, providing flexible signal acquisition capabilities for various industrial applications. Each channel of the General Electric IC694ALG223 incorporates a dedicated 12-bit analog-to-digital converter, delivering precise conversion with resolution of 4-5 μA per count depending on the selected input range. The module's compact single-slot design allows efficient use of rack space while supporting both local and distributed I/O configurations.

The IC694ALG223 Current Input Module demonstrates excellent performance characteristics with an update rate of 13 ms per channel and advanced diagnostic capabilities. When configured for 4-20 mA enhanced range, the module provides open-wire fault detection, alerting operators to connection issues within the current loop. The PACSystems IC694ALG223  General Electric also monitors external power supply status, enabling comprehensive system diagnostics through programmable feedback to the CPU. These features make the module particularly valuable in process control applications where signal integrity and reliability are critical.

With power requirements of 120 mA from the 5V DC backplane and 65 mA from an external 24V DC supply for current loops, the GE IC694ALG223 Input Module offers efficient operation. The module maintains strong noise immunity with common-mode rejection greater than 70 dB DC at frequencies up to 1 kHz, ensuring accurate signal acquisition in electrically noisy industrial environments. Factory calibration ensures consistent performance across all channels, with specific calibration values of 4 μA per count for the 4-20 mA range and 5 μA per count for other ranges.

The IC694ALG223 Current Input Module serves as an ideal interface for connecting transmitters, transducers, and other analog field devices to automation systems. Its configurable alarm settings and robust design make it suitable for demanding applications in manufacturing, process industries, and infrastructure systems. The module's combination of high channel density, precise conversion capabilities, and comprehensive diagnostics establishes the General Electric IC694ALG223 as a reliable solution for complex analog input requirements in modern industrial automation environments.
