Siemens 6ES5956-0AA12 SIMATIC S5 15V Module F For the 955 Power Supply CP535 Spare part
The Siemens 6ES5956-0AA12 is a robust and reliable power supply module from the legacy SIMATIC S5 programmable logic controller (PLC) family, designed to deliver stable 24 V DC power to S5 central racks and expansion units in industrial automation environments. With a continuous output current of 10 A, this module powers S5 CPUs, input/output modules, communication processors, and other system components in applications ranging from manufacturing and material handling to process control and infrastructure systems.
Although part of Siemens’ older S5 platform—now largely succeeded by the S7 series—the 6ES5956-0AA12 remains critical for maintaining brownfield installations in industries where S5 systems continue to operate reliably after decades of service. Its rugged construction, wide input voltage range, and built-in protection features ensure safe and uninterrupted operation in demanding industrial settings.
