Input circuit
Description
Sink input [-common]
Sink input means a DC input signal with current-flow from the input (X) terminal.
When a device such as a transistor output type sensor is connected, NPN open collector transistor output can be used.
Source input [+common]
Source input means a DC input signal with current-flow into the input (X) terminal.
When a device such as a transistor output type sensor is connected, PNP open collector transistor output can be used.
