Electrical Requirements Supply voltage The PC 444-W is a control cabinet PC with an Intel Celeron G3900 Skylake processor that is completely PC-compatible and operates with a standard PC BIOS. Using the HMI-Link G2 Expansion, HMI-Link (G2) terminals can be connected to the PC 444-W. This allows USB and display signals to be transmitted up to 100 m. +18-30 V DC (Class 2 or SELV and Limited Energy) (connection: 4-pin Phoenix) IDLE consumption without HMI-Link IDLE consumption with HMI-Link Max. consumption with HMI-Link Start current Article Number and Miscellaneous Article number Environmental Conditions Storage temperature Environmental temperature Humidity EMC tolerance Performance Data Processor Hard drive Main memory (DDR-RAM) Graphics Interfaces Real-time clock Intel Celeron G3900 128-Gbyte Solid State Disk 4-Gbyte DDR4 RAM (SODIMM) 0 … +50 °C 10-90 %, non-condensing EN 61000-6-2 (industrial area): EMC resistance EN 61000-6-4: noise emission Vibration tolerance Shock resistance Protection Type EN 60529: protected through the housing Intel HD Graphics 2x Ethernet 10/100/1000 Mbit 3x USB 2.0 2x USB 3.0 1x RS232 1x Audio (Line In, Line Out) 1x PS/2 Mouse 1x PS/2 Keyboard 1x DVI interface 1x Displayport 1x Local OUT (HMI-Link G2) y
