FANUCA03B-0801-C12364-Point 24 V DC Digital Input Module ID64C for Fanuc I/O Unit

Product Description

What this part is

A Fanuc ID64C digital input module, ordered as A03B-0801-C123 — a 64-point, 24 V DC input module for the Fanuc I/O Unit that hangs off the PMC side of a Series 11 or Series 15 CNC control. It reads 64 field devices — limit switches, proximity sensors, pushbuttons, relay contacts — and presents them to the PMC ladder. It is an input module: the card carries the Fanuc board number A16B-1310-0141 internally.

Decoding the order code

A03B: Fanuc prefix for I/O unit assemblies and the modules that populate them. Distinct from the board-level A16B / A20B prefixes and from the A02B control-unit prefix.

0801: the I/O Unit family group. A03B-0801 modules serve the Fanuc I/O Unit used on the System 10, 11, 12 and Series 15 generation controls.

C123: the specific module within that family, which Fanuc also names by its functional designation.

ID64C: the functional designation, and the field to work from. ID = digital input, 64 = 64 points, and the trailing letter identifies the module variant. Fanuc’s other module types use different mnemonics — OD for digital output, AD for analog input, DA for analog output — so the designation gives the direction of the module at a glance.

Published specifications

Points: 64.

Input voltage: 24 V DC.

Field connection: via connector.

Internal Fanuc board number: A16B-1310-0141.

Platform: Fanuc I/O Unit on Series 11 and Series 15 CNC controls; the A03B-0801 group also serves System 10 / 11 / 12.

Slot occupancy: one module slot in the I/O Unit base.

What these specs mean in practice

Sixty-four points on one card is dense, and the density has consequences: the field wiring lands on connectors rather than on individual screw terminals, so the connector and its wiring harness are as much a part of the installation as the module. The module designation is the exact match criterion — ID64C and ID64D are different modules, and the trailing letter is the only thing distinguishing them, so the designation printed on the card is authoritative over the A03B number alone.

Addressing follows the slot. The I/O Unit assigns module addresses by slot and by the unit’s configuration, and a 64-point module consumes a correspondingly large block, so a different slot moves every one of those 64 addresses in the PMC ladder.

Quantity and configuration

Sold as 1 piece — one input module. Takeout, tested, in an opened box. The I/O Unit base, interface and power module, 24 V field supply, field connectors and harness are separate items in the Fanuc I/O Unit system.

Interchange guidance

Searchable equivalents of the same part: A03B-0801-C123, A03B0801C123, A03B 0801 C123, ID64C, ID-64-C, A16B-1310-0141, A16B13100141. Related and distinct: A03B-0801-C127 (ID64D) and A03B-0801-C132 (ID32A) are different input modules in the same family, at a different variant or point count. Modules with an OD, AD or DA designation are output or analog cards, a different function.
