The Mainframe assy is a structure entirely made of aluminium, so as to meet the requirements of lightness and remarkable resistance. The Mainframe, shown in the figure below, is able to house 10 slots: the first two on the left are reserved to the SC-ETX and SC-MCC cards, the remaining 8 are reserved to the intelligent cards.Each slot is equipped with guides for an easy insertion of the cards. The BUS board presents, on the front side, all the connectors needed to link each card.
As shown in the figure below, at the back of the Mainframe the Power Supply / HUB Switch assy is present, which is composed of:a Power Suppy unit able to supply the +5Vdc voltage to power the cards and the ±15Vdc voltage to power the external sensors (by connecting each line to the BUS board).a 10/100 HUB Switch used to connect the external network line, the SC-MCC and SC-ETX cards.On the external side the following elements are present: the power lines indicators (n. 3 green LEDs), the RJ45 connector for 10/100 Mbps Ethernet network connection and the mains socket with integrated power switch.In the next subparagraphs a detailed description of the Power Supply and 10/100 Hub Switch units is given.
The Power Supply / HUB Switch assy shown in the figure below receives at the input the 220Vac 50 Hz mains voltage and generates all the needed output power lines.
A multi-port switch it's available and it can be used to manage high performance switched networks, by linking the SC-ETX card, the SC-MCC card and the external PC Networks.
Sensor Connectivity modules make the sensor connectivity a definitive hardware, you can plug different kind of modules to satisfy any needs.
