Surge arrester for surge protection in DC systems (sensors, power supply, communication), 24 V DC RSP-CL-TTL 2617110

Professional surge protection for DC systems

The RSP-CL-TTL surge arrester is an advanced T2 class solution designed specifically for DC power and communication systems. The device provides comprehensive surge protection for four signal lines with a common reference potential, making it an ideal solution for industrial applications requiring high reliability.

Technical parameters and construction

The device operates at a rated voltage of 24V DC, with a maximum continuous operating voltage of 33V DC or 23.3V AC. The design allows for a rated current of 1A, ensuring adequate performance for most signal and power applications in automation systems.

The arrester is designed for low bandwidth and low frequency signals, which guarantees effective protection without affecting data transmission quality. A common reference potential for all four lines simplifies installation and ensures consistent protection levels throughout the system.

Applications and compatibility

RSP-CL-TTL finds wide application in three main areas:

Sensing systems - protects temperature, pressure, level sensors, and other measuring devices against harmful surges that could damage precision measurement electronics.

DC power systems - secures power circuits for automation devices, PLC controllers, and other components requiring stable direct current voltage.

Communication systems - protects data interfaces from electromagnetic interference and surges that could interrupt information transmission or damage communication ports.

The common reference potential eliminates the problem of potential differences between signal lines, which is particularly important in long cable runs. The device requires no additional power or configuration - once connected, it immediately begins active protection of the entire system.
