3SE63 Safety Switch - RFID: Which 3TK28 Safety Relay can be used?

3SE63 Safety Switch - RFID: Which 3TK28 Safety Relay can be used?






QUESTION:
Can I use 3SE63 Safety Switch – RFID with all our 3TK28 Safety Relays or there are some restrictions?
RFID = Radio Frequency Identification


ANSWER:
The RFID safety switches 3SE63 can only be connected to the safety relays 3TK2826-*BB4*, 3TK2841-*, 3TK2842-*, 3TK2845* und 3TK2853-*BB40.

Attached you will find an example with the connection to 3TK2826-*BB4*.

Reason

The 3SE63 RFID safety switches have electronically outputs like a light curtain.
So they can be connected only to 3TK2826, 3TK284 und 3TK285 which are released for electronically inputs.

From these only the DC 24 V devices 3TK2826-.BB40, 3TK284 und 3TK285.-.BB40 can be used, because the devices with wide voltage range are internally isolated from the power supply and therefore independent from the power supply of the RFID safety switch.

On the other hand the 3SE63 RFID safety switches have an integrated cross-circuit monitoring, so they can only be connected to 3TK28, where the integrated cross-circuit monitoring can be switched off (see manual page 12).
It is not possible to switch off the integrated cross-circuit monitoring of the 3TK2840, 3TK2850, 3TK2851 und 3TK2852, so these 3TK28 cannot be used at 3SE63.
