4-channel selectivity for high-current loads Adjustable current thresholds (3-10A) Common signaling contact SITOP PSE200U series Robust construction

Product description

The Siemens SITOP PSE200U 6EP1961-2BA21 is a high-capacity 4-channel selectivity module for 24V DC power systems. It features a 40A input and provides four outputs, each rated at 10A. The current threshold for each channel can be individually adjusted between 3A and 10A, with a common signaling contact for fault indication.

This module is designed for applications requiring robust protection and monitoring of multiple high-current 24V DC loads. Its selective tripping capability ensures that an overload on one channel does not affect others, maintaining system stability. It is ideal for demanding industrial environments, machine tools, and large automation systems.

Stanlo Automation, a veteran-owned surplus parts distributor, provides the Siemens 6EP1961-2BA21. We are committed to delivering reliable automation solutions and surplus inventory to meet your operational needs efficiently and affordably.

Frequently asked questions

How does the Siemens 6EP1961-2BA21 protect individual 10A circuits?

The Siemens 6EP1961-2BA21 module protects individual 10A circuits by allowing you to set a specific current threshold between 3A and 10A for each of the four output channels. If a channel exceeds its set threshold, it trips independently, preventing damage to the load and other connected circuits.
