Data and Signal Surge Protective Devices (SPDs) – 2510 and 2520 Series

Bourns' SPDs feature a two-stage protection circuit that limits transients associated with gas discharge tubes and diodes

Image of Bourns' Data and Signal Surge Protective Devices – 2510 and 2520 SeriesBourns' 2510 and 2520 series of data and signal DIN-rail SPDs are designed to provide surge protection for one-pair or two-pair data lines with common reference potential in data, signal, and communication systems. They provide a maximum discharge current rating of 20 kA (8/20 μs), are UL 497B listed, and comply with the IEC 61643-21 standard. They are ideal for RS-232, RS-422, and RS-485 interfaces, low-voltage alarm circuits, high-frequency transmission systems, and analog/digital communications applications.

Features
  • UL listed data line protectors per UL 497B standard
  • Signal transmission is not interrupted when exchanging the module
  • Two-stage protection circuit limits transients associated with gas discharge tubes and diodes
  • Complies with UL 497B and IEC 61643-21, categories D1/C1/C2/C3
  • Pluggable surge protection for DIN-rail mounting
Applications
  • RS-232, RS-422, and RS-485 interfaces
  • Low-voltage alarm circuits
  • High-frequency transmission systems
  • Analog/digital communications
