The NI 6510 digital inputs are isolated from thecomputer power supply. Isolated photocouplers provide isolation.NI 6511The inputs in each bank of the NI 6511 device are isolated from the inputs in other banks, fromPX.COM pins in other banks, and from the computer power supply. All lines in the same inputbank use the same common. Isolated photocouplers provide isolation.NI 6512/6513The outputs in each bank of the NI 6512/6513 device are isolated from the outputs in otherbanks, from the +5 V and PX.GND pins in other banks, and from the computer power supply.All lines in the same output bank use the same common power and ground. Isolatedphotocouplers provide isolation.NI 6514/6515The inputs and outputs in each bank of the NI 6514/6515 are isolated from the inputs and outputsin other banks, from the +5 V and PX.GND pins in other banks, and from the computer powersupply. All lines in the same input or output bank use the same common power and ground.Isolated photocouplers provide isolation.NI 6516/6517The NI 6516/6517 has 32 channels that consist of four eight-line ports.
