*1 For KV-8000/KV-7000 Series
*2 Connectors for connector-type I/O units are not included. MIL40-pin slender connector kit OP-51404 and MIL40-pin connector kit OP-22184 are available separately.
*3 5 VDC mode can only be used with IN100 to IN115.
*4 If an overvoltage is detected, all inputs (IN100 to IN115) in the shared commons will be turned OFF until the power is cycled or until PRG is switched to RUN.
*5 The four input and output COMs (input COM0 and COM1, and output COM2 and COM3) are independent. For each COM, those with two terminals are short-circuited internally.
*6 Even if an overcurrent is detected at only one point, protection operation (output OFF) will be enforced for all of the outputs in the shared commons (COM2: OUT200 to 215, COM3: OUT300 to 315) and automatic recovery will be repeated until the cause is eliminated.
