I/O expansion for easyE4 control relays
Local expansion devices are connected directly to the right of the basic unit.
You can use the connector to connect the easyE4 base device to up to 11 expansions
and assemble them into a single device block.
Expansion devices come with an matching connector as standard.
You can use the expansion devices to:
l
Increase the number of inputs/outputs
l
Combine various voltages
l
Process analog/digital signals
You can use all digital and analog expansion devices regardless of the cor-
responding operating voltage.
Each expansion needs to be mounted individually on the mounting rail or with screws
and device feet, much like the base device. Once you are done mounting all the
devices, use the connector to combine them into a single device block.
Connect the base device to the expansion, and the expansions to each other,
with a connector.
