FANUCA03B-0801-C12764-Point 24 V DC Digital Input Module ID64D, 20 ms Response, for Fanuc I/O Unit

Product Description

What this part is

A Fanuc ID64D digital input module, ordered as A03B-0801-C127 — a 64-point, 24 V DC input module for the Fanuc I/O Unit that serves the PMC side of a Series 10, 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. Inputs are isolated, with a 20 ms response time, and the field wiring lands on connectors.

It is a digital input module. The card carries input points only.

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, serving the Fanuc I/O Unit on the System 10, 11, 12 and Series 15 generation controls.

C127: the specific module within that family.

ID64D: the functional designation, and the field to work from. ID = digital input, 64 = 64 points, D = the module variant. Fanuc uses different mnemonics for the other directions — OD for digital output, AD for analog input, DA for analog output — so the designation tells you what the card does at a glance.

What these specs mean in practice

The 20 ms response time is the number to check against the application. It is comfortable for pushbuttons, guard switches, pressure switches and general machine interlocks, and it is deliberately slow enough to reject contact bounce and electrical noise. Signals that must be captured within a few milliseconds — high-speed position capture, part-present sensing at speed, skip-signal inputs — belong on a high-speed counter or skip-signal input card.

The designation is what identifies the card: ID64D and ID64C are separate modules, and the trailing letter is the only thing separating them, so the printed designation on the card is the reference. Slot position matters too — the I/O Unit derives module addresses from the slot, and a 64-point card consumes a large address block, so a slot change shifts all 64 addresses in the PMC ladder.

Quantity and configuration

Sold as 1 piece — one input module. Takeout, tested, in an opened box. Scope of supply is the module itself.

Interchange guidance

Searchable equivalents of the same part: A03B-0801-C127, A03B0801C127, A03B 0801 C127, ID64D, ID-64-D, ID 64 D, A03B-0801-C127-R. Related but separate parts: A03B-0801-C123 (ID64C) is a different variant of the same point count, and A03B-0801-C132 (ID32A) is a 32-point module. Modules designated OD, AD or DA are output or analog cards.
