Siemens 6ES5324-3UR11 | SIMATIC S5 Interface Module

Product Description

The Siemens 6ES5324-3UR11 (IM 324R) is an interface module designed for the SIMATIC S5 automation platform, enabling seamless coupling of central controllers in the S5-115H and S5-155H PLC families. It provides synchronized communication between PLC racks, supporting up to 128 I/O points and multiple communication protocols including PROFIBUS DP, MPI, and Ethernet (configuration dependent).

Although officially discontinued in October 2022, this module remains critical for legacy automation systems and is available through specialized resellers for maintenance and repair operations. Its reliable construction ensures continuous operation in industrial and energy control environments.
