Product Description

The GE Fanuc IC697ALG441 is an Analog Input Expander module for the GE Series 90-30. The complete Analog subsystem includes Base Converter and two Expander modules – one for current and one for voltage. This component is the voltage expander module and it has 16 Channels. Each of these 16 differential inputs accepts up to 10V signals.  Like the current Expander module, the voltage Expander provides for additional inputs. This is done at a lower cost per point. The complete subsystem is able to accept up to a maximum of 120 points. There is no need for the user to configure DIP switches or jumpers when using this system. It is easy to configure using Windows programming software. A typical subsystem will comprise a base converter module and, when required, one or more expander modules. Users can increase the number of inputs of the total system up to a maximum of 120. This is done by creating a daisy-chain of up to seven Expander modules from the base converter.

Input Ranges:

Voltage: –10 volts to +10 volts Current: 4 to 20 milliamps


Default Scaling (16 bit) 312.5 microvolts per LSB step on voltage 0.5 microamps per LSB step on 4 to 20 mA No missing codes over 16 bits on voltage No missing codes over 14 bits on current NOTE: User scaling may introduce skipped codes in the lower 2 or 3 bits depending upon the factors used.

Accuracy: Calibration

Factory set at full scale = 10 volts ±2 millivolts on Base Converter module. Maximum errors at 25° C (77°F) are: Base Converter Voltage, ±.01% of full scale, ±.02% of value Base Converter Current, ±.05% of full scale, ±.1% of value Expander Voltage, ±.03% of full value, ±.02% of value Expander Current,

±.07% of full scale, ±.1% of value

Base Converter

Continually self-calibrates for zero and positive full scale (before user scaling) values. Field calibration not normally required; there is no zero adjustment. A trimpot on the Base Converter adjusts full scale value at 10V input. For critical applications this can be reset to compensate for ageing of the reference.

Accuracy: Linearity

±.02% of full scale over entire negative to positive range.

Temperature Coefficient

±5 PPM per °C typical ±15 PPM per °C maximum, voltage ±30 PPM per °C maximum, current

Input Impedance:

Voltage Inputs: Greater than 10 megohms at DC AC impedance, 20K ohms in series with 0.47 mfd capacitor. Current Inputs: 250 ohm, 0.1% precision shunt

Common Mode Rejection:

Voltage Range - Peak signal input must be between +13 and –13 volts with respect to the ANLGCOM terminal.


Response to common mode signals within the above limits is typically 70 dB CMRR, corresponding to a .02% full scale reading for a 0V input at 10 volts common mode. NOTE: Continuous input signals beyond the common mode range can result in abnormal conversions without causing alarms.


High-speed inputs on the Base Converter module may show some interaction between adjacent channels. This is typically .04% of the difference between the affected input and the adjacent channel input levels. The effect can be minimized by arranging inputs with similar levels on adjacent channels. There is no measurable interaction between Expander input channels.

Conversion Rate:

Base Converter inputs updated sequentially about every 2.4 ms to 2.8 ms (maxi- mum) for all 8 channels. One Expander input updated during each scan of the Base Converter inputs. Time between Expander updates = 44.8 x N ms

(N = number of Expander modules present).


Response Time:

Each input has a low pass filter with a 100 radians/second (0.01 second) cutoff. A digital filter on the Base Converter input channels adds a second pole at 450 radians/second. A sample and hold maintains full resolution. Settling times, to the specified accuracies, for a zero to full scale step input are as follows:

5.0% 30 milliseconds

1.0% 42 milliseconds

0.5% 51 milliseconds

0.1% 67 milliseconds

Input Protection:

Inputs isolated from VME backplane - but not between input channels. They are, however, protected from overvoltage to the levels listed below.


Inputs normally not affected by common mode damped ring wave of up to 1000 volts peak. Common or transverse mode peaks up to 2500 volts cause no damage, but may cause occasional bad data if they occur coincidentally with conversion of the affected channel.

Continuous Overvoltage:

Inputs survive common mode or normal mode 120 VAC or 125 VDC fault for at least 1 minute. Longer times may damage input current limiting resistor.

Damage limited to only the affected input.

Power Requirements:


Rack Backplane

+5 volts at 0.8A (4 watts) maximum for Base Converter

+5 volts at 0.4A (2 watts) for each Expander module

Field Side

No power required for the module; however, current for 4 to 20 mA inputs must be user supplied.

ERROR: '8373 - Base Module with Expanders Not Be in Any Slot Lower Than 4'


Error 8373: AI base module with expanders must not be in any slot lower than slot 4.


On a PACSystems RX7i rack, when an analog input base module (IC697ALG230) has expander modules (IC697ALG440 or IC697ALG441) following it and there is no other base module before the expanders, the base module must be in slot 4 or higher.

Note: The base module must always precede its expander modules on a rack, that is, the base module must always be added to a slot that has a lower number.


Customer Questions and Answers

  • Question:  What is an IC697ALG441?  Answer:  The IC697ALG441 is an Analog Input Voltage Expander module from the GE Fanuc 90-70 Series. 
  • Question:  From what is this module an expansion?  Answer:  IC697ALG441 is an expansion from the IC697ALG230 Analog Input module. 
  • Question:  What type of wiring is used between the modules?  Answer:  A simple parallel wiring is used between IC697ALG230 and IC697ALG441.
  • Question:  What should my reference address be?  Answer:  You can set it up as A/I 0009. This means when you go to your analog input table, you will be looking from address number 9-17 for your channels. 
  • Question:  Should I be looking for anything when testing this module?  Answer:  You should make sure that ALL OK lights are ON and NOT blinking. If they are blinking, then you can try powering it off for a second or two and then powering it back up. 
  • Question:  What should I be looking for with the channels when testing IC697ALG441?  Answer:  You want to make sure all the channels are in good, working order.
  • Question:  What should I do if there is a problem with my IC697ALG441?  Answer:  Your product may need repair
