Wiring an Ultrasonic Proximity Sensor to the Click PLC

[@thaskarthaskaran1425]

Hello sir, How to connect low voltage sensor to plc please reply the sensor output also low voltage.? What must be the voltage for connecting to plc x pins?

[@ACCautomation]

Hi Thaskar, In order to connect low voltage sensors to the PLC, an interposing relay is usually used. This can be mechanical or solid-state. Low voltage is usually referred to less than 5 VDC. accautomation.ca/wiring-interposing-relays/ This post should help you out. Regards, Garry

@@ACCautomation Thank you . How much min voltage required does 12 v enough

Actually the thing is I want to connect the raspberry pi output which is 3v to plc . Can it be done by boosting the voltage.?

@@thaskarthaskaran1425 You would have to look at the specifications of the input of the PLC that you are using. This would be listed as a minimum voltage level. Regards, Garry

@@thaskarthaskaran1425 To interface with a PLC you would either get a relay output board for your raspberry pi or get an interposing relay. www.automationdirect.com/adc/shopping/catalog/relays_-z-_timers/solid_state_relays/socket_mount_relays,_4a_(ad-70s2_series)/ad-70s2-04b This link will show a solid-state relay that has an input of 3-30 VDC input. 8-12mA draw for the input. I hope this helps you out. Regards, Garry

can i connect a vfd to this PLC to adjust the speed of a 3 phase motor please sir answer

[@ACCautomation]

Hi Kinsley, Yes, you can connect to a variable frequency drive and control the speed. Usually, you will have local or remote modes on the VFD. The local mode can control the VFD through digital and analog signals on the PLC. Remote control would usually involve a communication protocol like Modbus TCP, Modbus RTU, Ethernet IP, etc. Here is a video showing Modbus RTU communication to control a 3 phase motor. kzbin.info/www/bejne/aYvTd6SCZpdjZqs Regards, Garry

how can i program proximity sensor to click plc than to a vfd of 20 hp please answer sir.The ladder language can you please help me sir

Hi Kinsley Jolicoeur, You are missing a lot of information from your question. - How are you communicating with the VFD? - What VFD are you using: Model / Options? - What proximity sensor are you using? Make / Model - What is the sequence of operation of the proximity sensor in relation to the VFD? Here is a link to the five steps for program development. accautomation.ca/five-steps-to-plc-program-development/ It will help you in explaining what you are trying to achieve. Thanks, Garry
