Siemens 6GK1561-4AA01 Programmable Logic Controller Module

Siemens 6GK1561-4AA01 is the SIMATIC NET CP 5614 A2 PCI communication processor, a PCI card that provides two PROFIBUS DP interfaces for master and slave connections to a PROFIBUS network. Each interface supports PROFIBUS DP data rates from 9.6 kbit/s up to 12 Mbit/s via RS-485 9-pin sub-D connectors, enabling integration with PLCs and PC-based controllers. The module is a 32‑bit PCI card that draws 5 V DC from the backplane and ships with DP-Base software, a DP-RAM Interface for a DP master, a single installation license, runtime software, and a CD-ROM containing the electrical manual in two languages (German and English). 6GK1561-4AA01 corresponds to CP 5614 A2, and these specifications position it for use in SIMATIC NET environments requiring dual PROFIBUS DP connectivity.
