This item is suitable for providing a quick overview of the status of each switch in the chain, while the safety relay is already integrated. The reduced wiring effort is due to the AR technology, while the product is easy to service using plug-in connection terminals. In terms of design and functionality, the use of AR evaluation units and AR switch chains is possible with the evaluation of up to 12 devices.

Note that all relevant status information on the switches connected is routed to the evaluation unit, with the use of only two inputs. There are 14 monitoring outputs, with the CER-AR-AES supplies delivered with information in the switch state, along with numerous other useful diagnostic messages.
