The MCOR corrector chassis must interface with different types of control systems presently in use. In order to accommodate these control schemes, as well as any future configurations, the MCOR crate architecture places the total control system interface on a single VME-standard card. This interface card occupies the left-most slot of the crate. It is responsible for monitoring voltage reference inputs, output voltages and fault conditions. BiRa Systems MCOR Crate Interface Card
MCOR Interface Card Physical Description
The Bi Ra Model 2512-C4 interface card is a standard VMEbus-compatible 6U by 220 mm board installed in slot 0 in an Eurocard crate. Two 96-pin I/O connectors connect the interface card to the MCOR crate’s backplane. The Interface card employs sixteen test jacks in the front of the card to enable local measurement of the MCOR output currents. A second set of front test jacks enable local measurements of the reference voltages. A front mounted reset switch sets the interface’s Crate OK latch and resets the MCOR’s fault protection latch. An optional crate door switch sets the Inhibit Bus to the Inhibit state when the crate door is opened.
MCOR Interface Card Functional Description
The Model 2512-C4 Crate Interface card functions as a control-monitor interconnect between an MCOR magnet driver crate backplane, current set-point reference voltages, system fault/enable discrete lines and magnet-current monitoring signals input to a analog monitor. The Interface card can be used in sixteen Bi Ra 2510 (MCOR12) systems or eight 2510R30 (MCOR30) systems.
The interface card provides a simple, inexpensive, application-adaptive capability for magnet power systems by concentrating control-protective circuitry on a single card that can be adapted to system control/monitoring requirements. This simplifies interfacing in a diversity of control and monitoring regimes because the MCOR magnet driver modules need not to have the specialized circuitry for interfacing to the many possible control system implementations.
