Siemens 6ES7307-1BA01-0AA0 is a PS307-regulated power supply module for SIMATIC S7-300 controllers, delivering a stable 24 V DC output at up to 2 A. It accepts AC input of 120 V or 230 V and provides the supply needed for the S7-300 CPU and peripheral modules in a rack. The module includes electronic short-circuit protection (non-latching) and supports parallel wiring for higher current requirements when multiple PS307 units are used. This 6ES7307-1BA01-0AA0 variant is the 2 A PS307 power module in the S7-300 power family and is designed to reliably regulate DC power within industrial PLC installations.
