Description
The GE IC693ALG223 is a 16-channel analog current input module designed for the Series 90-30 PLC platform. This module serves as an interface between field instruments and the PLC, converting analog current signals into digital values for processing. It supports 16 single-ended input channels, each independently configurable for 0–20 mA, 4–20 mA, or 4–20 mA Enhanced input ranges. It is widely utilized in process control, manufacturing, water treatment, and power generation applications.
Features
- 16-channel single-ended analog current inputs
- Configurable input ranges: 0–20 mA, 4–20 mA, and 4–20 mA Enhanced
- 1500 VAC field-to-logic isolation for surge protection
- Integrated 200 Hz low-pass input filtering
- LED indicators for module status and external power monitoring
- Compatible with Series 90-30 5-slot and 10-slot baseplates

Installation Guidelines
- Ensure the PLC system is powered down before inserting or removing the module from the baseplate.
- The module occupies a single slot in any Series 90-30 5-slot or 10-slot baseplate.
- Use shielded twisted-pair cabling for analog signals to minimize EMI/RFI interference.
- Ensure proper grounding of the cable shields at the field instrument or the panel entry point.
- Verify that the 24 VDC external power supply is correctly connected to the module terminals.
- Handle with care using ESD-safe practices to prevent damage to internal circuitry.
FAQs
What is the difference between the IC693ALG223 and IC693ALG222?
The IC693ALG223 is designed specifically for current inputs (mA), whereas the IC693ALG222 is designed for voltage inputs (VDC).
What is the required external power for this module?
The module requires 120 mA from the +5 VDC backplane and 65 mA from a 24 VDC external user supply.
How many modules can be installed in a system?
The number of modules depends on the specific CPU model; for instance, Model 311/313/323 supports up to 4 modules, while larger systems like 351/352 support up to 51 modules.
