Analog Output Function

The A03B-0823-C006 analog output module provides four output channels for machine designs that require analog reference or control signals from the CNC/PMC I/O system. FANUC documentation assigns CH1 and CH2 to T1 and CH3 and CH4 to T2, helping technicians identify the correct field-wiring terminals during replacement.

This unit is an expansion module, not a stand-alone I/O Link master or basic module. It connects to the preceding compatible basic or expansion module through CA106, while CA105 provides the connection to a following expansion module when the original configuration requires one.

Model Identification

Organic search results also describe A03B-0823-C006 as a FANUC analog output module, FANUC Terminal Expansion Unit E, and FANUC CNC I/O extension module. These descriptions reflect its documented function.

Do not confuse it with A03B-0823-C005 Expansion Module D, which is documented for analog input. Modules with similar housings or nearby C-numbers should not be treated as direct replacements without checking the complete FANUC order number and machine configuration.

Compatibility Check

Before ordering, verify the following:

• Complete part number: A03B-0823-C006
• Existing terminal-type I/O basic and expansion-module sequence
• CA105/CA106 inter-module connection arrangement
• T1 and T2 field wiring
• Rotary-switch setting
• CNC/PMC I/O assignment and machine-builder configuration
• Required analog signal type and connected load
• Physical condition of the terminal blocks and inter-module cable

A missing or incorrect analog output can also result from field wiring, an external load, module addressing, PMC logic, or the preceding basic module. Confirm these items before replacing the hardware.
