Looking to add a "high oil temp" warning on a machine tool by adding a temperature switch into the hydraulic circuit, right after the radiator before returning to tank. I know monitoring from the tank would be better, but tapping into the tank is not possible.
The switch I would like to use....
....is rated for 120/240 AC.
I would like to use the switch to trigger an input on my PLC. The switch is normally open and would close at over temperature, allowing a +24vDC to connect to the PLC input(PNP).
Can this switch, as only rated for AC, be used to carry the low-amperage +24vDC signal?
