Why distributed process I/O?

Siemens distributed process I/O acquires and outputs process signals from sensors and actuators. Designed for SIMATIC PCS neo and PCS 7, it ensures high availability and flexibility for your operations.

Process industries face complex signal processing and high safety demands. Our distributed I/O systems reliably process diverse signals, centrally or locally, supporting protocols like 4-20mA/HART, PROFIBUS or PROFINET.

Modular designs help you remain flexible for plant adaptation to reduce engineering overheads. Use PROFINET for secure, real-time communication and bridge the digital gap to the field. Protect your investment with compatibility for predecessor products and extended availability for future expansion.
