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.
