Festo P.BE-CPX-F8DE-P-E N en 1610a English
This sample application shows the circuitry of a button with a
light signal. Actuation of this button can only be evaluated
while clock signal connection T0 of a channel pair is connec­
ted to a 24V power source. At the same time, the LED on the
button lights up to indicate the possible evaluation of this
actuation.
Mode 1/2
0 V
T0 E0
This circuit only functions by a changeover between function
modes 1 and 2 in the safety program.
Note
The safety-related evaluation in this example is only pos­
sible on the following connection blocks:
– CPX-M-AB-4-M12X2-5POL-T
– CPX-AB-8-KL-4POL.
When using the connection block CPX-AB-8-KL-4POL (connec­
tion technology "CageClamp") another sensor/switch can be
connected to the channel pair used via terminals 24V and E1.
