Compact Ethernet data isolator with two RJ-45 ports

Black Box Corporation

Black Box Ethernet Data Isolator SP427A 2×RJ-45

SKU CH-TBNQ-M474V

An in-line Ethernet isolator that protects equipment from ground loops and surges while drawing power from the network, meeting EN6060-1 for medical use

  • Protects equipment from ground-loop damage via electrical isolation barrier
  • Maintains Ethernet/Fast Ethernet or Gigabit communication across isolation
  • Draws power from network and connected equipment — no extra supply needed
  • Compact in-line design installs directly into existing cabling
  • Meets EN6060-1 medical standard and RoHS compliance

Black Box SP427A Ethernet Isolator

This compact Black Box SP427A sits in-line between two RJ-45 links and maintains Ethernet or Gigabit communication across an electrical isolation barrier. It draws operating power from the network and connected equipment so no external supply is needed. The unit protects attached gear from ground-loop damage and harmful surges that cross segment boundaries. It is built for new installations where galvanic isolation is required on copper Ethernet.

Suited for copper Ethernet links needing isolation

Network engineers who must break ground loops between switches, servers or medical devices on standard copper runs will find this isolator fits directly in-line. It meets EN6060-1 and the European Medical Device Directive, so it can be deployed in clinical environments. Buyers who require fibre-optic interfaces or isolation for speeds beyond Gigabit Ethernet will not be served by this model. The device is also unsuitable for links that cannot supply the modest power it draws from the line.

Dual RJ-45 Gigabit isolation with EN6060-1 rating

The decisive specification is the pair of RJ-45 ports that pass up to Gigabit Ethernet while providing galvanic isolation certified to EN6060-1. This single figure tells an installer whether the isolator matches the cabling, speed and regulatory needs of the segment. No external power input, no additional connectors and no higher-speed ratings are present on this unit.

商品問答

What Ethernet speed does the SP427A isolator support up to?

The SP427A maintains communication up to Gigabit Ethernet across the isolation barrier.

How does the SP427A isolator mount in a network run?

It installs in-line using its two RJ-45 ports and requires no external power supply.

What is the first step when installing the SP427A isolator in-line?

Connect each RJ-45 port into the network cable run so the isolator sits between the two segments.
