Description
xA02B-0283-B801 – FANUC CNC Control Base Unit (Description)
Overview:
The FANUC A02B-0283-B801 is a 1-slot standalone basic control unit / backplane chassis used in industrial CNC (Computer Numerical Control) systems. It’s part of the FANUC A02B-0283 series — a family of foundational hardware designed for integrating modular control electronics in machine tools.
Function:
-
Acts as a basic control platform/backplane for CNC controls, providing a slot to install the necessary control cards (CPU board, memory, I/O modules, interface cards, etc.).
-
It does not include the electronics themselves — these must be installed separately. It serves more like the structural and connector backbone inside a FANUC CNC controller cabinet.
Series & Compatibility:
-
Typically associated with FANUC 18i-MB / 180i-SB / 16i / 18i / 21i series CNC controllers, depending on configuration and board setup.
-
Can interface with servo drive systems and other control modules in complex multi-axis machine tools.
Key Characteristics:
-
📌 Part Type: 1-slot basic control unit / PCB backplane
-
📌 Role: Structural base for control electronics (not a complete controller by itself)
-
📌 Industrial Use: Designed for CNC machines (milling machines, lathes, machining centers, etc.) where modular FANUC electronics are installed.
-
📌 Standalone Form Factor: Does not include display, CPU, memory, or I/O boards — those are added depending on the machine’s requirements.
-
📌 Weight: Lightweight backplane module (around ~0.15–0.38 lb / ~0.17 kg in many listings).
-
📌 Environmental Limits (as typical hardware): Designed for industrial ambient rates — operable from around 0 °C to ~55 °C and high humidity conditions (non-condensing).
