FANUC Fanuc A20B-8101-0401 Module Detailed Explanation
1. Basic module positioning
A20B-8101-0401 is an I/O module in the FANUC CNC system, which is an extension component of the FANUC 0i/16i/18i/21i/30i series CNC systems. It is mainly used for digital signal acquisition and control, connecting peripheral devices such as sensors, buttons, relays, etc. of machine tools.
2. Key parameters and specifications
Parameter details
Model A20B-8101-0401
Type I/O module (digital input/output)
Applicable systems FANUC 0i/16i/18i/21i/30i series
The number of I/O points is usually 16/16 (16 inputs+16 outputs) or 32/32 (32 inputs+32 outputs) (depending on the version)
Input signal 24V DC (standard industrial voltage)
Output signal transistor output (usually supports 24V DC)
The communication interface is connected to the CNC system through FANUC I/O Link (serial communication)
The installation method is usually installed on the I/O unit (such as A20B-2000-xxx series) or directly integrated into the control cabinet
3. Main functions
Digital signal acquisition (such as limit switches, buttons, sensor signals)
Digital signal output (such as control relays, solenoid valves, indicator lights, etc.)
PLC logic control (in conjunction with FANUC PMC to achieve machine tool automation logic)
Expand I/O capability (when the number of I/O points on the CNC motherboard is insufficient, more input/output channels can be expanded)
4. Typical application scenarios
Numerical Control Machine Tool (CNC): Used to control tool changing, coolant switch, safety door detection, etc.
Automated production line: Interact with robots, conveyor belts, and other equipment to achieve automated processing.
PLC logic expansion: Increase the number of I/O points in the FANUC PMC system to meet complex control requirements.
5. Relationship with other modules
The relationship with the motherboard (such as A20B-8200-0384): The motherboard is responsible for core CNC operations, while the I/O module is responsible for peripheral signal interaction.
The relationship with network cards (such as A20B-8101-0450): Network cards are used for network communication, while I/O modules focus on local signal control.
6. Common alternative or compatible models
A20B-8101-0400 (similar to I/O module, may have different points)
A20B-8101-0402 (version with higher I/O points)
