Protection Circuitry  
The eight banks of eight drivers in the PXI-2567 and SCXI-1167  
protect against overvoltage and overcurrent conditions. When the  
condition clears, the channel is automatically reset so no disassembly  
of the module is required. A fly-back diode is also included to protect  
against damage from inductive loads.
