A20B-1003-0350

The part number A20B-1003-0350 from FANUC functions as a spindle control PCB, specifically engineered for various CNC applications within the FANUC 16, 18, and 21 Series ensemble. This control board is designed to ensure reliable signal routing through the terminal strip interface, making it integral for the operation of spindle motors.

A terminal block and ribbon header serve as the primary connectors, presenting a straightforward means for integration. This PCB operates using TTL-level digital I/O, ensuring compatibility with modern digital logic systems. For optimal performance, the device requires an operating temperature variance from 0°C to 60°C and manages humidity levels of 95% or lower without condensation.

This board supports a voltage rating that encompasses both 5V DC logic and 24V DC input, catering extensively to various operational needs. The mounting type is PCB-mounted and capable of fitting within standard rack configurations, facilitating ease of installation. Passive convection is the chosen cooling method, allowing thermal management without fans, which adds to system reliability.

Weighing in at 1.13 kg (approximately 2.49 lbs.), this unit is designed for stable and secure operation in environments that are free of corrosive gases, enhancing its longevity in industrial settings. The installation orientation of the A20B-1003-0350 allows for horizontal placement in rack slots, providing flexibility in setup and use.
