Hi Pradeep What Omron relay do you have? www.omron.com/ecb/products/pry/ Example: Here is the information on the Omron LY Series Relays: www.ia.omron.com/data_pdf/cat/ly_ds_e_4_5_csm54.pdf?id=949 We would specify a coil voltage. This would be the voltage needed to turn on energize the relay to cause the contact to switch. LY2N 110/120 If this relay were wired to the output of the PLC. You would wire your 120VAC supply in series with the output point of the PLC and the coil of the LY relay. If you have this as an input to the PLC you would have a sensor (Limit Switch / Proximity / ect.) power up the coil of the LY2N 110/120. One of the dry contacts from the relay will then be wired in series from the 24VDC power supply to the input of the PLC. Connects like the ones mentioned above are called interposing relays. Here is a wiring diagram of an interposing relay. qph.ec.quoracdn.net/main-qimg-1ce89c0b48f4b9c14aa816e171c99ab8 The switch is energizing the 12VDC coil of the relay. The contacts from the relay are switching the 120VAC lamp. Hope this helps you out. Regards, Garry
