Digi International 76002060 WR21 AC Standard firewall appliance

Industrial Firewall Appliance

The Digi International WR21 AC Standard is a firewall and network security device built for industrial and commercial environments. It provides managed network protection for sites that require a dedicated hardware appliance rather than a software-only solution. The unit suits integrators and IT teams deploying secure remote access or network segmentation.

Standard Temperature Operation

The appliance is rated for standard temperature ranges typical of indoor equipment rooms and sheltered cabinets. It ships with an AC power supply for direct connection to mains electricity. No acoustic or thermal performance figures are published in the supplied data.

AC Power Kit Included

The bundle includes the AC power kit required for immediate installation in standard electrical environments. This removes the need to source a separate power adapter or DC wiring harness. No additional software licences or mounting accessories are detailed in the specifications.
