Siemens 6FC5111-0CA01-0AA0 Digital Input Module

Siemens 6FC5111-0CA01-0AA0 is a DMP Compact digital input module for SINUMERIK CNC systems, providing sixteen 24 V DC digital input channels. Designed for use with SINUMERIK CNC platforms such as the 840C/840CE/840D/840DE family, this module plugs into the DMP Compact I/O assembly to receive real-time 24 V digital signals from sensors and switches. The 16 inputs are configured for sinking operation, enabling straightforward interfacing of standard 24 V devices to the CNC controller. The 6FC5111-0CA01-0AA0 designation identifies the 16-input DMP Compact module, ensuring compatibility with SINUMERIK hardware ecosystems that rely on compact, CNC-focused I/O components. Typical applications include wiring limit switches, home sensors, and other digital condition signals that the CNC controller must read quickly and reliably in a compact, rack-mountable form factor.
