Hi, Can someone help me out? Please excuse my terminology because I'm a complete newcomer to PLCs.
The PLC at work is modular/expandable and rack-mounted. I need to connect a float switch identical to this one to the PLC.

It is normally open. As the water level rises, the switch is made and becomes closed circuit. There are 2 wires coming from the switch and these need connecting to the PLC, such that the PLC can monitor when the switch goes to the closed position. My understanding is that the switch can work from 5VDC.
My question is: what type of module do I need to output 5V to the switch? Do I need to define "switch closed" as an X (input) parameter to the PLC?
Please let me know if you need clarification and I will do my best to clarify.
Thanks in advance.
