The IC697ALG440 is a current input expander module for GE Fanuc‘s Series 90-70 PLC family, designed to increase the system’s analog input capacity. The IC697ALG440 must be paired with an IC697ALG230 base converter module, to which it connects via the expansion bus. The IC697ALG440 provides 16 dedicated 4–20 mA current channels, converting analog field signals into digital data for the PLC. Each channel can be individually scaled, and the module includes an analog multiplexer to connect inputs sequentially to the base converter’s A/D. Up to seven expanders can be cascaded, allowing a total of 120 inputs per base converter. The IC697ALG440 is configured entirely in software, requires no jumper settings or DIP switches, and can be replaced without rewiring or reconfiguration.
Process control (chemical, petrochemical, refining)
Temperature, pressure, flow monitoring
Power generation gas turbine exhaust monitoring
Motor current and bearing temperature tracking
Water/wastewater treatment and tank level detection
Manufacturing and material handling automation
16 dedicated 4–20 mA current inputs – High density expander adds 16 current channels to the system
Software‑only configuration – No jumpers or DIP switches; MS‑DOS or Windows programming software
Individual user scaling – Per‑channel engineering unit scaling
Optical isolation from backplane – Blocks conducted noise and protects controller
Integrated analog multiplexer – Sequentially connects expander inputs to base converter A/D
Diagnostic capabilities – Status LED, error detection, channel response detection, module health monitoring
Works exclusively with base converter – Requires IC697ALG230 as master; up to 7 expanders per base
Removable terminal board – Field wiring stays intact when module is replaced
Up to 120 total inputs system – Base converter (8) + up to 7 expanders (112) = 120 inputs
Factory calibrated with EEPROM – No field calibration required
Converts 4–20 mA current loop signals into 16-bit digital data for the PLC.
Uses an analog multiplexer to connect its 16 inputs, one at a time, to the A/D converter on the base converter module.
Provides optically isolated inputs to protect the backplane from field wiring transients.
Communicates with the base converter module via the expansion bus (terminals 36–40).
Updates one expander channel during each base converter scan; all 16 expander channels are cycled sequentially.
Supports user scaling to convert raw A/D counts into engineering units (e.g., pressure, flow, temperature).
Reports diagnostics via status LED and fault contacts to the PLC I/O fault table
Q1: What is the IC697ALG440 used for?
A1: The IC697ALG440 is a 16‑channel current input expander that adds analog input capacity to GE Series 90-70 PLC systems when paired with an IC697ALG230 base converter.
Q2: How many IC697ALG440 modules can be used in one system?
A2: Up to seven IC697ALG440 expander modules can be daisy‑chained to a single base converter module, providing up to 120 total analog inputs.
Q3: Does the IC697ALG440 require hardware jumpers to configure input ranges?
A3: No. The IC697ALG440 is configured entirely via MS‑DOS or Windows programming software, with no jumpers or DIP switches required.
Q4: What is the update rate for expander channels?
A4: The base converter updates one IC697ALG440 channel per scan. The time between updates for each expander channel is 44.8 × N milliseconds, where N is the number of expander modules in the system.
Q5: Can the IC697ALG440 be replaced without rewiring?
A5: Yes. The IC697ALG440 uses a removable terminal board; field wiring remains connected when the module is replaced, and no reconfiguration is required.
