CES-AR-AES-12 Evaluation Unit


The CES-AR-AES-12 Evaluation Unit provides central evaluation of up to 12 CES or CET switches in a chain with individual status outputs for each switch.Downstream parts of the safety circuit can be monitored using a feedback loop.The evaluation unit is good for Category 4 PLe according to EN ISO 13849-1.These systems are designed for use in areas where a high level of tamper resistance and safety is required and feature an inductive RFID read head,evaluation unit / safety module,and a digitally coded actuator.Up to 12 Unicode or Multicode CES switches can be wired to the Evaluation unit.*See Switch Compatibility below.

Note: The connection set needed for this Evaluation Unit (sold separately) is part number 104776.
