Interposing relay connection to plc

It would help someone help you if you could provide the forum with the PLC you have and the digital output/input module your using.

Are you trying to control the relay with an output or are you trying to connect the relay's contacts to an input?

we are using MITSUBISHI FX5U-32MT/ES TYPE PLC..

we are in need to control the Permanent magnet dc motor through DC contactor via interposing relay..

so we need to connect the relay to plc output port and then

I am not familiar with your PLC, but I am sure those that are will jump in.

could you send me the one more pdf file for input side of plc...mickey

Thank you
 
Okay, the X01, X02, etc are inputs. Outputs have a Y01, Y02 designation.

You want to wire on the relay:

PLC Output - A1
24V Power Supply (-) - A2

That will pull your coil in when the output turns on.

Where did the "sensor" come in?

Your questions are so vague. Are you trying to connect input sensors or output relays?

Is the motor contactor and relay in your case same thing. You connect one side to PLC outputs and other to Motor?
