Greetings colleagues! I need to connect Microsonic wms-35/RT ultrasonic sensor to PLC. The peculiarity of this sensor is that it does not have a standard interface, but has 2 interface pins: One pin must be pulled up to gnd for a time ~80us, after which the second signal pin appears on the echo-signal of binary form (sound wave return - 1 otherwise 0, VCC). Please help with the choice of connection option. Maybe X20DS1319 modules or something similar will be suitable here? Operating voltage UB10 - 30 V d.c., reverse polarity protection. No-load current consumption≤ 30 mA. ![Pins](https://europe1.discourse-cdn.com/brcommunity/original/2X/c/c173f51f4ab933bc1c768ec19c61b607f729f6b6.jpeg) ![wms](https://europe1.discourse-cdn.com/brcommunity/original/2X/4/46a58c4844b22f8b46a0af959c32d594a872daf4.jpeg) ---
