Siemens 6EP1961-2BA00 Industrial Interface Module

Siemens 6EP1961-2BA00 SITOP select DIAGNOSEMODUL is a four‑channel diagnostic interface for SITOP power‑supply systems. It provides four 24 V DC diagnostic inputs and four 24 V DC outputs (each channel up to 10 A, for a total of 40 A) to monitor and power connected loads or branches. Each channel features an adjustable current threshold (2–10 A) so a fault or overload on a branch can be detected and signaled quickly, enabling proactive protection of the DC rails. As part of the SITOP SELECT diagnostics family, the module reports status to controllers or HMIs, supporting rapid fault isolation and improved uptime in automation environments. Typical applications include monitoring critical loads and redundancy paths within SITOP-powered control panels and manufacturing lines, where reliable DC power and clear diagnostics are essential. The 6EP1961-2BA00 is designed to integrate with Siemens SITOP power supplies and related diagnostic signaling, providing a compact, centralized way to supervise multiple DC circuits without adding separate sensing hardware.
