Siemens 6EP1 961-2BA00 Four Channel Analog Input Module

Siemens 6EP1 961-2BA00 (also listed as 6EP1961-2BA00) is a SITOP SELECT four‑channel diagnostics module designed to monitor four independent 24 V DC feeders in a SITOP power‑distribution system. It accepts four 24 V DC input lines and provides a shared 24 V DC output rated up to 40 A, with each channel’s current limit adjustable from 2 A to 10 A, enabling selective shutdown and fault isolation of individual feeders while keeping other loads powered. This module is intended for use with Siemens SITOP SELECT hardware to improve fault diagnosis and system availability in industrial automation applications. Typical applications include supervising multiple 24 V rails in control cabinets, isolating a faulted branch without dropping entire subsystems, and providing per‑channel current‑limit protection to safeguard connected devices. As part of the SITOP SELECT family, the 6EP1 961‑2BA00 integrates with compatible SITOP power supplies and distribution components to deliver a compact, centralized protection and monitoring solution for PLC environments.
