The RMC-2101 provides nine available slots for either the FOI-2xxx or FOI-4xxx fiber optic isolator series.
The tenth available slot must be occupied by a PSM-2010 power supply module. Each RMC-2101 will be shipped with one PSM-2010. A second PSM-2010 may also be added for power redundancy, leaving eight available slots for any fiber optic isolator. If the first PSM-2010 fails, the second PSM-2010 will take over the entire system load and carry on normally. Each fiber optic isolator must also be accompanied by a CMA-2001 chassis mount adapter, which slides the fiber optic isolator into the slots and assures correct alignment of the isolator power connector to the power bus inside the RMC-2101. FiberPlex recommends an "R" chassis for high security applications because they have added power line filtering to contain their RFI emissions.
