ATEN 8-Channel Relay Expansion Box

VK248

  • An Ethernet-to-relay channel box ships with 8 channels of relay output
  • Supports Power over Ethernet (PoE) or DC power supply
  • Supports Telnet CLI (command-line interface) mode for third-party system integration
  • An expansion solution for connecting more relay channels to ATEN Control System

The ATEN Relay Expansion Box VK248 is a powerful Ethernet-based expansion solution designed to extend the functionality of the ATEN Control System. Equipped with 8 relay output channels, the VK248 enables centralized control of a wide range of devices, including projection screens, projector lifts, motorized blinds, lighting systems, and other relay-controlled equipment.

Using standard Ethernet connectivity, the VK248 can be deployed across a network and easily integrated with ATEN controllers through a LAN connection. This flexible architecture allows system integrators and facility managers to expand control capabilities without complex wiring or location constraints.

The VK248 also supports comprehensive Telnet CLI commands, making it suitable for integration into commercial, industrial, and customized automation environments.
