DC surge protector for protecting data/signal lines, 48 V DC RSP-4L-48 2617118

Data and Signal Line Protection – Reliability in Every Circuit

This DC surge protector, designed to protect data and signal lines, is a key element in ensuring the continuous operation of control, communication, and automation systems. The device effectively protects against the effects of surges that can damage sensitive electronic components. It provides protection for four signal lines or two pairs of lines, making it a versatile solution in many applications.

This surge protector is characterized by an extremely fast response time – less than 1 nanosecond (≤ 1 ns) for Line-Line and Line-PG protection. This feature is particularly important in systems where even short-term voltage spikes can lead to serious failures. The maximum continuous operating voltage is 54 V DC (38 V AC), allowing it to be used in a wide range of installations.

Installation and operating parameters

The device is designed for direct mounting on a 35 mm rail (according to PN-EN 60715 standard), which simplifies and speeds up installation. Compact dimensions (95 x 7 x 98 mm) and low weight (68 g) allow for discreet mounting even in tight spaces. The surge protector retains its properties in a wide range of ambient temperatures, from -40°C to +80°C, guaranteeing reliable operation in various environmental conditions. The IP20 protection class of the housing provides basic protection against touch and contamination.
