Siemens 6FC5 611-0CA01-0AA1 Printed Circuit Board

Siemens 6FC5 611-0CA01-0AA1 Sinumerik 24VDC digital I/O module is the 72-input / 48-output I/O interface for Sinumerik CNC controls. Packaged as a PP72/48 module with 24 VDC logic signals, it provides high-density I/O for connecting sensors, switches, and actuators to the Sinumerik controller. The unit is available in a coated variant, designed for harsher industrial environments, and carries the order number 6FC5 611-0CA01-0AA1. In typical configurations it delivers 72 digital inputs and 48 digital outputs, with outputs rated at up to 0.25 A per channel, enabling reliable drive of solenoids, relays, or small contactors. This module slots into Sinumerik systems to extend I/O capacity without external gateways, supporting common applications such as machine tool control, automation cells, and turnkey CNC setups where robust, compact 24 VDC I/O is required.
