GE Fanuc IC655ALG516 / IC655ALG566 / IC655ALG567 Series Five Analog Modules
An eight-channel analog input and two distinct two-channel analog outputs with different ranges and data direction.
Shared Role, Then Model Differences
These modules share the Series Five intelligent analog I/O context but serve different signal paths. IC655ALG516 digitizes field inputs; IC655ALG566 and IC655ALG567 generate outputs.
IC655ALG516 supports eight channels across 1–5 V, 0–10 V, ±10 V and 4–20 mA selections. IC655ALG566 provides two 0–10 V or 4–20 mA outputs. IC655ALG567 provides two bipolar ±10 V outputs.
Common Specifications and Model-Specific Data
Signal Range and Data Format
Hardware range, field wiring and program scaling must describe the same engineering units. A correct catalog number with the wrong range jumper or scaling can still produce an unsafe value.
Input path
Sensor → IC655ALG516 → input registers.
Unipolar output
Output registers → IC655ALG566 → voltage/current actuator.
Bipolar output
Signed command → IC655ALG567 → ±10 V actuator.
Records to Preserve Before Removal
Step 1
Record each channel range, wiring polarity and program scaling.
Step 2
Verify the required 24 VDC external supply and signal grounding.
Step 3
Install the exact input or output identity; do not substitute by family prefix.
Technical Questions
Which analog-control boundary links IC655ALG516 / IC655ALG566 / IC655ALG567?
They are Series Five analog modules requiring coordinated field wiring, range selection and register scaling.
Which model in IC655ALG516 / IC655ALG566 / IC655ALG567 is an input module?
IC655ALG516 is the eight-channel analog input.
How do the two output models in IC655ALG516 / IC655ALG566 / IC655ALG567 differ?
IC655ALG566 provides 0–10 V or 4–20 mA; IC655ALG567 provides bipolar ±10 V.
Why must scaling be reviewed for IC655ALG516 / IC655ALG566 / IC655ALG567?
The PLC register value must match the selected hardware range and the engineering units of the field device.
What is a practical acceptance test for IC655ALG516 / IC655ALG566 / IC655ALG567?
Check several calibrated points per channel, including polarity for bipolar ranges, and compare PLC data with a traceable measurement.
Which calibration record should travel with IC655ALG516 / IC655ALG566 / IC655ALG567?
Keep channel range, polarity, register scaling and calibrated field values so each analog path can be proven after replacement.
