WebMicroelectronic devices using open drain output may provide a 'weak' (high-resistance, often on the order of 100 kΩ) internal pull-up resistor to connect the terminal in question to the positive power supply of the … WebIn other words, the PLC “thinks” the contactor will be energized any time-discrete output channel 0 is energized, but that may not actually be the case if there is an open fault in the contactor’s coil circuit. This may lead to a dangerous condition if the open fault in the contactor’s coil circuit is later cleared.
