2-wire proximity sensor compatibility (3)
Yes (all 2-wire proximity sensors at 24 VDC)
3-wire proximity sensor compatibility (3)
Yes (all 3-wire proximity sensors at 24 VDC)
(1) for U = 11 V,
(2) see compatibility of sensors with type 1 and 2 rapid inputs,
(3) the auxiliary inputs are rapid inputs (response time < 50 μs or < 250 μs) dependent on the maximum permitted frequency (1 MHz or 40 kHz) of the counter inputs,
(4) with the loss of the sensor supply voltage, the rapid auxiliary inputs can be taken into account.
NOTE: If the auxiliary inputs/outputs remain unused on one TSX CTY 2C module, it is possible not to wire the auxiliary supply. In this case, it is recommended to hide the "auxiliary I/O supply" fault.
NOTE: For more information on these functions, refer to the application manual.
Illustration
The auxiliary inputs use a 24 V supply provided via the connector.
