SD-DSCLA 2964898 Phoenix Contact Dc selective protection module With status feedback contacts

Product Details

Phoenix Contact SD-DSC LA (Order No. 2964898) is a selective protection and monitoring module specially designed for DC power supply systems, suitable for 24V DC industrial power supply applications. This device can achieve precise short-circuit detection and selective disconnection of downstream load circuits, effectively avoiding power outages of the entire system due to local faults, and significantly enhancing the availability and safety of the control system. The module supports DIN rail mounting and integrates status feedback contacts, facilitating remote monitoring of the operating status.

Core Features

The SD-DSC LA module, by real-time monitoring of the output current, quickly cuts off the faulty branch when a short circuit occurs, while maintaining continuous power supply to the main power supply and other load circuits. Its built-in electronic trip mechanism features a fast response speed and high precision, enabling selective protection without the need for additional fuses, simplifying system design and reducing maintenance costs.

This module is equipped with a normally open status feedback contact, which can be used to connect to a PLC or monitoring system to transmit "normal/faulty" status signals in real time, supporting predictive maintenance and remote diagnosis. All wiring is completed through through-hole spring connection terminals, making installation and replacement quick and reliable.

Typical applications

SD-DSC LA is widely used in distributed DC power supply systems that require high availability, such as factory automation control cabinets, process instrument power supply networks, robot control systems, rail transit signal equipment, and energy management systems. It is particularly suitable for occasions where independent protection of multiple load branches is required and fault isolation is needed without affecting the main system.
