Siemens 6ES7407-0DA02-0AA0 Programmable Logic Controller Module

Siemens 6ES7407-0DA02-0AA0 is a PS407 power supply module for the SIMATIC S7-400 PLC system. It accepts 120/230 V AC input and provides 5 V DC at up to 4 A to power backplane circuitry and mounted I/O modules, enabling stable operation of the S7-400 rack. This 6ES7407-0DA02-0AA0 part number identifies a 4 A, wide-range power module within Siemens' PS407 family, designed to be installed in compatible SIMATIC S7-400 enclosures and to integrate with other PS-series modules for coordinated power distribution. Common applications include industrial automation installations where a compact, rack-mountable 5 V DC supply is required to feed logic modules and peripheral devices in the same rack, with operation from either 110–120 V or 200–240 V networks depending on regional requirements. The module is part of Siemens' official catalog for S7-400 power supplies and carries the PS407 designation, reflecting its 4 A output and 5 V DC regulation, suitable for powering PLC backplanes and motor drive interfaces when used in appropriate combinations within the S7-400 family.
