ATEN 8-Channel Digital I/O Expansion Box VK258

The VK258 8-Channel Digital I/O Expansion Box provides an additional eight channels of digital input/output for a flexible expansion of the ATEN Control System. This allows users to control more digital I/O devices, such as various sensors, dry contact devices, PCs, and motor-driven devices in environments where more devices need to be centrally controlled. With the advantage of the Ethernet-based connection, the expansion box easily connects to the ATEN Controller via a LAN connection from different locations across a network.

  • Provides 8 Digital I/O channels to expand the ATEN Control System
  • Up to eight VK258 expansion boxes can be added to a single ATEN Controller
  • Flexible Deployment – connects to an ATEN Controller via an Ethernet connection
  • ID Switch pairs the VK258 with a controller to instantly configure the network settings
  • One DC output allows you to power I/O or other low-voltage devices that require an extra power supply
  • Supports Power over Ethernet (PoE) or DC power supply
  • Firmware upgradable through USB, firmware upgrade tool, or web interface
