The GE Fanuc IC697ALG440 expands the analog input capacity of your Series 90-70 PLC system. This module provides 16 current input channels, each accepting the industry-standard 4 to 20 milliamp signal. Furthermore, the IC697ALG440 converts these analog signals into digital values with 16-bit resolution for precise process monitoring. The module updates all channels in only 2.4 milliseconds, ensuring timely data for control loops. You must use this expander together with a base converter module and a voltage expander module to build a complete analog input subsystem. This modular approach gives you flexibility in configuring your system.
The IC697ALG440 accepts current inputs ranging from 4 to 20 milliamps, which is the most common signal standard for industrial sensors and transmitters. Each of the 16 channels connects to the analog multiplexer, which sequentially routes inputs to the analog-to-digital converter. This switching circuit connects one input at a time, ensuring accurate conversion for each channel. The module represents the converted data in 2's complement format, which simplifies digital processing. Additionally, the module features factory-set calibration at 10 Volts plus or minus 2 millivolts, ensuring consistent performance out of the box.
The IC697ALG440 delivers excellent measurement accuracy for demanding process applications. The module provides plus or minus 0.07 percent of full scale accuracy, which translates to precise readings across the entire input range. Additionally, it offers plus or minus 0.1 percent accuracy of the measured value, ensuring reliable data for critical control decisions. The 16-bit resolution gives you 65,536 discrete steps across the input range, enabling detection of small signal changes. Such high accuracy and resolution make the IC697ALG440 suitable for applications requiring precise monitoring, such as flow control, pressure measurement, and temperature sensing.
The IC697ALG440 works as part of a three-module analog input subsystem. You need a base converter module, a voltage expander module, and this current expander to complete the system. The base converter handles the primary analog-to-digital conversion and communication with the CPU. You can mix and match these expander modules with the base converter to achieve up to 120 input channels total. This modular design allows you to scale your analog input capacity according to your application needs. Furthermore, you must locate the IC697ALG440 in the same rack as the other expander modules, positioning them adjacent to each other for proper interconnection.
The IC697ALG440 includes several diagnostic features that simplify maintenance and troubleshooting. Status indicator LEDs provide visual confirmation of module health and operation. Error detection facilities alert you to potential issues before they affect process control. Additionally, the module offers expander channel response detection, which verifies that each channel communicates properly with the base converter. Module health diagnostic facilities continuously monitor the internal state of the expander. These features help you identify problems quickly and reduce downtime in your automation system.
Connecting the IC697ALG440 requires attention to proper wiring practices. Terminals 36 and 38 on the base converter module carry the analog expansion signal for this current expander. For differential data bus connections, you can use terminals 37 and 39, which function as serial communication ports. Pay careful attention to polarity when connecting the cables to ensure correct signal transmission. If you use shielded cables, connect the shield ground to terminal 35. Shielding is optional but recommended in environments with electrical noise. Additionally, ensure all wiring connections are secure and properly insulated to maintain signal integrity and prevent measurement errors.
The IC697ALG440 draws 0.4 Amps (2 Watts) from the 5 Volts DC backplane supply. This modest power consumption makes it suitable for systems with multiple modules. The module weighs approximately 0.61 kilograms, which is relatively light for a 16-channel analog device. Its compact form factor fits into a single slot in the Series 90-70 rack. The module has no user-adjustable calibration settings, as the factory performs calibration before shipment. This approach simplifies installation and ensures consistent performance across all units.
Installing the IC697ALG440 follows a straightforward procedure. First, power off the PLC chassis and disconnect mains supply. Next, select a slot in the same rack where you will mount the base converter module and other expander modules. The IC697ALG440 must sit adjacent to its associated expander modules for proper interconnection. Slide the module into the slot along the guide rails until it seats firmly against the backplane connector. Then, tighten the retaining screws to secure the module. After installation, connect the expansion signal wires from the base converter to the appropriate terminals. Power on the system and verify that the status LEDs indicate normal operation. Finally, configure the analog input parameters using your programming software.
