The VK258 provides Ethernet-to-digital I/O connectivity with 8 channels of digital input/output. It allows users to remotely access digital input / output devices from a PC or any system located anywhere. The complete Telnet CLI commands are fully integrated into users’ commercial and industrial applications.

What’s more, the VK258 serves as a flexible expansion box of the ATEN Control System, enabling 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 Ethernet-based connection, the expansion box can be easily connected to controllers via LAN connection from a variety of locations across a network.
