The Simatic PX130C adapter from Siemens integrates standard sensors into the IO-Link, the communication standard for the sensor/actuator level. This adapter is equipped with functions such as: signal conditioning functions, rotational direction recognition, speed monitoring, input inversion, switching time measurement and timers with extended pulses. The diagnostic functions monitor connected sensors for wire breaks, short-circuits and overcurrent/undercurrent. Up to two binary proximity switches or a single analog sensor can be connected to the adapter.
