The K-PCBA24 is necessary to drive EE-SX1 103 sensor built-in motorized stage without using our controller. Generally, for the motion control module of a motion control board or sequencer, the photo coupler is used as the sensor input terminal and terminal current of approximately 10mA is required. A sensor voltage of approximately 24V is necessary. The EE-SX1 103 sensor is operated with a power supply voltage of 5V and it can run an output current of approximately 1mA. For this reason, when you use the motion control module of a motion control board or sequencer, the EE-SX1 103 sensor is destroyed. It is possible to obtain an output current of up to 500mA at a power supply voltage of 24V.
