Siemens 6ES7138-4CB11-0AB0 ET200S Power Module

Siemens 6ES7138-4CB11-0AB0 ET200S Power Module (PM-E) is the power-distribution unit for the SIMATIC ET 200S distributed I/O system, delivering the main supply to connected I/O modules while providing onboard diagnostics to monitor the rail status. It supports dual input ranges: DC 24–48 V and AC 24–230 V, allowing you to configure the power source to match your installation. The PM-E plugs into the ET200S base, incorporating a protective fuse and diagnostic features that help you quickly identify power faults and ensure reliable operation in automation cabinets. Typical applications include remote I/O expansion on manufacturing lines and machine-control enclosures, where a compact, fuse-protected power source for ET200S modules is essential for stable, centralized power distribution and easy maintenance.
