This 4-channel module accepts 24V DC input up to 12A and provides four individually adjustable outputs (0.5–3A each). Its integrated common signaling contact and three-color LEDs per channel enable immediate fault identification, reducing troubleshooting time. Part of the SITOP series, the 6EP1961-2BA11 ensures selective disconnection of loaded circuits, critical in distributed automation architectures.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications Breakdown\u003c\/h2\u003e\u003cp\u003eThe Siemens 6EP1961-2BA11 operates from a 22–30V DC input with a rated input current of 12A.

For instance, in a CNC machining center, each axis drive can be independently monitored and isolated without shutting down the entire control cabinet. This failure mode analysis approach prevents cascading faults and reduces downtime.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eMount the Siemens 6EP1961-2BA11 on a standard DIN rail (EN 60715 35x7.5\/15). Input wiring uses two screw terminals (0.5–16 mm²) for +24V and two (0.5–4 mm²) for 0V. Each output uses a single screw terminal (0.5–4 mm²). A DIP switch configures the startup delay: 25 ms, 100 ms, or load-optimized sequential connection. Use the potentiometer on each channel to set the trip threshold between 0.5 and 3 A. Ensure natural convection with 50 mm clearance above and below.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing the Siemens 6EP1961-2BA11, verify your incoming supply voltage range (22–30V DC) and total load current (max 12A input, 3A per output). For high-reliability applications, consider the remote reset function via a non-isolated 24V input. Order the optional device identification label (3RT2900-1SB20) for clear panel marking.
