With the central coupling of a basic unit and expansion, you can have a unit with 24 inputs and up to 16 outputs. Comprehensive circuit-diagrams are easy to implement in this fashion.

Expandable 'easy' basic units are also available in a cost-effective version without an integrated display.

'easy'-Link – simple decentralized expansion

In order to solve control tasks which are separated from one another, you require additional decentralized inputs and outputs. Just connect the Easy 200-Easy with an expandable basic unit. Using a simple two wire cable, you can connect the 'easy'-expansion which may be up to 30 m away.

easy 800 with integrated easy NET

Example: The integrated easy NET network

The easy 800 control relays can be connected to one another easily and with low cost. The integrated NET is available for this purpose. Up to 8 easy 800 units can communicate with one another over a distance of maximum 1000 meters using this feature. It does not matter if the respective devices are running their own programs or being used as a distributed input/output module.

Additionally, all easy 800 units can be expanded locally with the easy-Link interface. This enables the universal use of easy control relays in automation applications ranging from 12 to over 300 I/O points.
