![](/p.gif) | 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. 1x VK258 8-Channel Digital I/O Expansion Box 1x Rack Mount Kit 9xTerminal Blocks 1x User Instructions More information: Features | Module type | Digital | ![](/p.gif) | Signal direction | Input/output | ![](/p.gif) | Channels quantity | 8 channels | ![](/p.gif) | Digital input channels quantity | 8 channels | ![](/p.gif) | Digital output channels quantity | 8 channels | ![](/p.gif) | Ethernet LAN (RJ-45) ports | 1 | ![](/p.gif) | Supported network protocols | ARP, ICMP, TCP/IP, DHCP, HTTPS, SSH | ![](/p.gif) | Nominal output voltage | 12 V | ![](/p.gif) | Input impedance | 0.3 Ω | ![](/p.gif) | Product colour | Black | Logistics data | Master (outer) case width | 250 mm | ![](/p.gif) | Master (outer) case height | 175 mm | Weight & dimensions | Width | 75.8 mm | ![](/p.gif) | Depth | 130 mm | ![](/p.gif) | Height | 42 mm | ![](/p.gif) | Weight | 550 g | ![](/p.gif) | Package width | 59 mm | ![](/p.gif) | Package depth | 239 mm | ![](/p.gif) | Package height | 160 mm | ![](/p.gif) | Package weight | 708 g | Operational conditions | Operating temperature (T-T) | 0 - 50 °C | ![](/p.gif) | Storage temperature (T-T) | -20 - 60 °C | ![](/p.gif) | Relative humidity | 0 - 80 % | Power | Power consumption | 300 mA | ![](/p.gif) | Power consumption note | DC5V:2.2W:36BTU, POE:2.75W:39BTU |
