DC surge protector for protection of data/signal lines, 24 V DC RSP-4L-24 2617117

Data and Signal Line Protection – Reliability in Every Circuit

The RSP-4L-24 surge protector is a key element protecting sensitive devices and systems from the effects of sudden voltage increases in DC circuits. Designed to protect data and signal lines, it effectively minimizes the risk of damage caused by surges, ensuring the continuity of installation operation. This model is particularly useful in applications where signal stability is critical – automation, control, telecommunications or monitoring systems.

Construction and principle of operation

This surge protector protects up to 4 signal lines or 2 pairs of lines, making it a versatile solution for various installations. Its construction based on a two-stage protection circuit – spark gaps and TVS diodes – guarantees a quick and effective response to surges. The protection against overvoltage response time of ≤ 1 ns (Line-Line and Line-PG) provides almost instantaneous protection against harmful impulses. This ensures that surge limitation occurs before it can damage connected devices.

Operating parameters and application

The rated operating voltage of 24 V DC and the maximum continuous operating voltage of 33 V DC (for DC) make the surge protectors from the RSP-4L series ideal for standard low-voltage installations. The maximum continuous operating voltage for AC is 23.3 V. This surge protector finds application wherever protection of delicate electronics against interference from the power supply network or induced by external factors is required. Example areas of application include:

• Alarm and fire systems
• Building automation installations
• Control and regulation systems
• Telecommunication equipment
• Laboratory and measuring equipment
• CCTV and video surveillance systems

The RSP-4L-24 surge protector is mounted directly on a 35 mm rail (PN-EN 60715), which facilitates its installation and integration with existing systems. The IP20 degree of protection provides basic protection against accidental contact. The weight of the device is only 68 g, and its dimensions are 95 x 7 x 98 mm, allowing for easy adaptation to limited mounting space. The use of high-quality materials guarantees long-lasting and reliable operation of the device in various environmental conditions.
