Easy719-AB-RC Expansion

(1/1)

Bob 5:
I need to do a panel that has 5 incoming 24vac signals/contacts but i also have some inputs i need for control switches. How do i expaned the easy as the I/O expansions are 24vdc or 100-240vac. Could i put a dc expansion on or would it be better to put relays on the incoming signals and use a dc easy and expansion.

Urs:
I would recommend to go with the same Voltage for all involved PLC components.
This should facilitate life of maintenance guys.
Why not use a Digital input interface device similar to the one you can find if you enter below string into your favorite search engine?

DEK-OE-230AC/48DC/100 or DEK-OE-120AC/48DC/100
