CES-AR-AES-12 (Order no. 098225)

Описание

• Central evaluation of an AR switch chain
• Status of each individual switch can be seen
• For switch chains of up to 12 devices
• Four individual safe relay contacts
• Category 4/PLe according to EN ISO 13849-1

Important: A switch chain comprising the following switches can be connected to the AR evaluation unit: CES-AR-C01 / CES-AR-C02 / CES AR-C04 / ESL-AR / CET- AR / CTP-AR FunctionThe AR evaluation unit is used to evaluate the individual safety switches in a CES-AR-... switch chain and the safe interruption of a safety circuit. The unit has two inputs for connection of a CES-AR... switch chain. The safety contacts are switched as a function of the input signals. Downstream parts of the safety circuit can be monitored using a feedback loop. The switching states of the connected safety switches can be signaled by means of monitoring outputs. If the actuator on one of the safety switches in the switch chain is moved out of the operating distance, the AR evaluation unit opens its contacts and the corresponding monitoring output is reset. The system is designed so that failures will not result in the loss of the safety function. The occurrence of failures is detected by cyclic self-monitoring at the latest at the next demand to close the safety contacts. The system can be started either manually using a start button or automatically. Category according to EN ISO 13849-1Due to two redundant safety paths (relay contacts) with 2 internal, monitored normally open contacts per safety path, suitable for:

• Category 4/PL e according to EN ISO 13849-1

Each safety path is independently safe. LED indicator
