Description
Product Description
The IC693ALG220 is a four-channel analog input module developed for the GE Fanuc Series 90-30 PLC platform. It is engineered to acquire and convert analog signals from field instruments such as transmitters, sensors, and control devices into digital values for processing within the PLC system.
This module supports bipolar voltage inputs in the range of -10 to +10 VDC, making it suitable for applications requiring precise measurement of dynamic analog signals. With 12-bit resolution and stable conversion performance, it ensures consistent data acquisition in process control environments.
The IC693ALG220 incorporates channel-to-ground isolation and high noise rejection capability, which enhances signal integrity in electrically noisy industrial settings. Its fast 4 ms update rate allows near real-time monitoring, while factory calibration minimizes the need for manual adjustments during commissioning.

FAQ
Q: Does the IC693ALG220 support current inputs (4–20 mA)?
A: This model is primarily designed for voltage inputs (-10 to +10 VDC). External signal conditioning is required for current signals.
Q: How accurate is the module in real applications?
A: Typical accuracy is ±10 mV, with a maximum deviation of ±30 mV depending on operating conditions.
Q: Is recalibration required after installation?
A: No, the module is factory calibrated and generally does not require field calibration.
Q: Can it be used with other GE PLC series?
A: It is specifically designed for Series 90-30 systems and is not directly compatible with 90-70 or RX3i platforms.
