Siemens 6ES5324-3UR11 IM324R Module

Core Performance & Industrial Application

The Siemens 6ES5324-3UR11 is the IM324R coupling interface module for the SIMATIC S5-115H / S5-155H redundant controller family.

It connects and couples the central processing units of redundant S5-H systems, enabling hot-standby redundancy in critical control loops.

It plugs into the S5 central rack as a backplane-mounted interface module for redundant data exchange between paired CPUs.

It is a discontinued genuine Siemens spare part kept for legacy S5-H redundancy system maintenance.

It serves as direct replacement for failed coupling boards in old S5-115H/155H PLC installations.
