Siemens 6ES7158-3AD00-0XA0 PN/PN Coupler

The Siemens 6ES7158-3AD00-0XA0 PN/PN coupler couples two PROFINET networks for seamless data exchange in distributed I/O systems. This coupling module acts as an IO device on both networks, enabling transparent communication between different automation islands. It transfers up to 2,048 bytes of I/O data in each direction, facilitating substantial data throughput.

Technical Specifications of Siemens 6ES7158-3AD00-0XA0

The Siemens 6ES7158-3AD00-0XA0 coupling module features two PROFINET interfaces with integrated two-port switches for network flexibility. It supports the Media Redundancy Protocol (MRP) for high network availability. The module operates on a 24 V DC supply and draws approximately 250 mA of current. Each side of the coupler provides electrical isolation, protecting the connected networks from electrical disturbances. The device provides clear LED indicators for immediate diagnostic feedback.
