Chinese 3-Wire NPN/PNP Proximity Sensor DIN Mount Breakout Boards
Overview
Generic Chinese DIN mount breakout boards for 24V powered NPN/PNP proximity sensors. They have a switch to configure whether or not the on-board resistors/LEDs are pull-up or pull-down, for either NPN or PNP sensors. In either case, the aggregated signals are directly connected to the sensor inputs. The LEDs are dual color to indicate if any pull-up or pull-down current is being drawn, which in turn means the sensor is activated.
