More Information

Overview Manuals I/O Group Signal Limits Installation Module Selection

Features:

  • Adds 24 digital inputs and 16 digital outputs to a connector-panel I/O Link group.
  • Uses the Expansion B configuration without a manual pulse generator interface.
  • Works as one of as many as three local extensions behind a connector-panel basic unit.
The module expands machine-side signal capacity without creating a separate I/O Link group.

Its role and position are defined by the basic-unit connection, flat cable and extension selector.

Cabinet layout must keep wiring and ventilation clear while respecting the documented output limits.

The GE Fanuc A03B-0815-C003 Connector Panel I/O Expansion Module B may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Basic and Extension Relationship

  • Basic Unit: A03B-0815-C001 begins the local connector-panel I/O group.
  • Expansion Capacity: One basic unit accepts as many as three local extensions.
  • Expansion Role: A03B-0815-C003 contributes 24 inputs and 16 outputs without an MPG interface.
  • Address Position: The rotary selector follows the occupied extension position, including gaps.

Digital Output Boundaries

  • Point Load: Each output supports up to 200 mA including momentary current.
  • Saturation: The on-state saturation voltage is 1 V maximum at 200 mA.
  • Off State: Leakage current is limited to 20 µA maximum.
  • Response Path: The 50 µs driver delay is added to I/O Link transfer and ladder-scan time.

Cabinet and Cable Practices

  • Enclosure: Install the connector-panel modules in a fully enclosed cabinet.
  • Clearance: Keep at least 100 mm above and below the module group for wiring and ventilation.
  • Ventilation: Do not place heat-generating equipment below the I/O modules or cover basic-unit vents.
  • Inter-Unit Cable: A03B-0815-K100 provides the 20 mm flat connection for 32 mm module spacing.

Connector-Panel Variants

  • A03B-0815-C001: Basic unit with 24 inputs and 16 outputs.
  • A03B-0815-C002: Expansion A with 24 inputs, 16 outputs and an MPG interface.
  • A03B-0815-C003: Expansion B with 24 inputs and 16 outputs but no MPG interface.
  • A03B-0815-C004: Expansion C with sixteen 2 A outputs.
  • A03B-0815-C005: Expansion D for analog input signals.
Description
GE Fanuc A03B-0815-C003 is a connector-panel I/O Expansion Module B that adds 24 digital inputs and 16 digital outputs to a local FANUC I/O Link group; this version does not incorporate a manual pulse generator interface.

A connector-panel basic unit and as many as three local extensions form one I/O Link group, so A03B-0815-C003 is selected and positioned as an extension rather than used as a stand-alone basic module.

For dependable cabinet integration, A03B-0815-C003 is installed in a fully enclosed enclosure with ventilation space kept clear; its documented digital outputs support up to 200 mA per point and include the I/O Link transfer plus ladder-scan time in the response path.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does GE Fanuc A03B-0815-C003 fail to join the expected local I/O group?
Check that GE Fanuc A03B-0815-C003 is connected behind the connector-panel basic unit, that the flat cable is seated correctly, and that the extension position selector matches the occupied position.
Can GE Fanuc A03B-0815-C003 replace an extension that needs a manual pulse generator interface?
No. GE Fanuc A03B-0815-C003 is the Expansion B version without an MPG interface; verify whether the installation instead requires the documented Expansion A variant.
What should be checked when a GE Fanuc A03B-0815-C003 output will not drive its load?
For GE Fanuc A03B-0815-C003, confirm the 24 V output circuit, common wiring and load current; each documented output is limited to 200 mA including momentary current.
How is GE Fanuc A03B-0815-C003 positioned when an earlier extension slot is unused?
Set the GE Fanuc A03B-0815-C003 extension selector for the actual occupied position described in the connector-panel I/O manual, rather than assuming that physical order alone defines its address.
Why must GE Fanuc A03B-0815-C003 be installed inside a closed cabinet?
GE Fanuc A03B-0815-C003 requires a fully enclosed cabinet to limit contamination and must retain ventilation and wiring clearance above and below the module.
Which inter-unit cable is documented for GE Fanuc A03B-0815-C003?
GE Fanuc A03B-0815-C003 uses the A03B-0815-K100 flat cable; the manual specifies a 20 mm cable when adjacent units are spaced 32 mm apart.
