provide isolation between the input circuits, the INTKM01/IMSET01 interface, and the output circuits.
The communication between the NTST01 unit and the INTKM01 and IMSET01 modules is accomplished by RS-485
standard lines, through the connector P2 on the INTKM01/ IMSET01 interface which converts the internal signals into the RS-485 standard. The voltage regulators and DC-to-DC converters generate the 24 VDC, all the output voltages to supply the input circuits, the INTKM01/IMSET01 interface, and the output circuits. All voltages generated by the block are controlled by the power supply control that puts the NTST01 unit in bypass if one of
the voltages is absent.
