Siemens R61H00-203 Power Module Assy

Siemens R61H00-203 Power Module Assy is a Siemens-made power module assembly described in reseller listings as a Power Conditioner or Power Supply module, indicating its role as a compact power-conditioning component within a Siemens automation system. The part number is listed as R61H00-203 (also seen as R61H00203), with references in sources such as Radwell and Electrical.com noting the designation and its availability in the secondary market. Several listings identify the item as used or surplus, and Radwell explicitly notes it is discontinued by the manufacturer, which can affect availability and warranty terms depending on the seller. Because detailed electrical specifications (voltage, current rating, mounting footprint, and exact compatibility) are not provided in the widely accessible listings, buyers should verify fit with their specific Siemens hardware before purchase. In practice, this part is encountered in older Siemens control or drive systems that require an integrated power module assembly, offering a replacement option when original inventory is scarce.
