Stores Interface Box

The Stores Interface Box (SIB) is an LRU, which is required to function in a high reliability safety critical environment. Its function is to control a number of other subsystems based on commands received from two open architecture computers over 1553B Buses. The SIB is configured as dual redundant hardware including power supply to enhance the reliability. The SIB is packaged in a ½ Air Transport Rack (ATR) size enclosure with overall dimensions L=355mm, W=124mm, H= 194mm. The SIB consists of 3 PCBs of size 233.35 X 160 mm(6U Double Euro) in the main card cage and a set of 2 smaller PCBs of size 75 mm X160 mm and 65mm X 160mm in the side compartment which houses the ARINC S700 connector.The 3 PCBs in the main card cage plug into a 3 slot VME back-plane with P0, P1 & P2 connectors. The input and output signals to/from the SIB through a combination of Round shell MIL 38999, ARINC S700 Rack & Panel, and tri-axial SMA connectors. In addition set of 34 electro-mechanical relays, DC-DC converter modules and associated RF filters to derive the required operating voltages for the various circuits (+5V and isolated +28V) from the 28VDC input equipment supply also in the Rack.The SIB is dissipate around 40 watt depending on the loading and duty cycle.
