Tips: What is open collector output?An open collector output is an NPN transistor. NPN transistors allow leakage current in the common terminal. It can be thought of as a switch that allows the circuit to be connected to a common terminal after a load. This means that a power supply is needed if have output. The power supply must be connected to the output after going through load, or NPN transistor is only to establish a path to the common end, which is a dry contact. Therefore, if measure an open collector output voltage that is not connected to any power supply, there is no voltage change. If the open collector is working properly, the voltage should be detected after going through the output load.
