This industrial computer enables complex system configuration with only a low overall height (2U) due to its butterfly backplane design. The 19″ chassis is based on the PICMG 1.3 standard and offers space for up to 6 expansion cards. In addition to front-accessible USB and PS/2 ports, the case has a powerful fan module with replaceable air filter mats, guaranteeing maintenance-friendly operation. In this industrial PC there are 2x 3.5″ drive bays and one optical drive in slim design. An AC or DC ATX power supply and optional redundant versions are supported by the system. In addition to a lockable door on the front, the case also has LEDs that indicate the system status.
