Coding aThermal Overload Relay?
Coding aThermal Overload Relay?
(OP)
I was contemplating the you-beaut software features that are packed into today's PLC hardware, how if one had a mind to in an application with motors, it would presumably be quite feasible to code the thermal overload function if the line current was available as an input.
Feasible, maybe, but does anyone know if this is actually done in practice?

But the next question is; why reinvent the wheel? Many SSOLs are now available with communications ports so they are already doing the protection internally under an approved algorithm and can just send the pertinent information into the PLC.
