6ES7960-1AA06-0XA0 Siemens Synchronization Module

Description

6ES7960-1AA06-0XA0 Siemens Synchronization Module is a short-distance synchronization module designed for the SIMATIC S7-400H system, with a maximum synchronization distance of 10 meters. Its core function is to connect two CPU 41xH units in S7-400H sub-units, enabling reliable short-distance synchronization between redundant controllers. The module directly inserts into the reserved slot of the CPU 41xH, with each CPU requiring two such modules for proper operation.

Key technical specifications include a 24V working voltage, 50-60Hz output frequency, and 3C product certification. For engineering configuration, it is fully compatible with all STEP 7 programming languages, supporting easy program migration between standard and redundant S7-400H systems; when loading programs, the system automatically transmits data to both redundant controllers, and users can set parameters for specific redundant functions via STEP 7.

Equipped with integrated self-diagnostic capabilities, the module detects potential faults early and sends signals, enabling targeted component replacement to minimize downtime. It supports hot-swapping of all components during system operation; after CPU replacement, programs and data are automatically reloaded. Additionally, users can modify programs, adjust configurations such as adding or removing DP slaves or modules, and alter CPU memory allocation while the system is running, effectively preventing shutdowns caused by controller failures. Ideal for applications in power, water supply, airport lighting, and marshalling station systems.
