System Interface Terminals A And B - Festo EduTrainer 8071407 Operating Instructions Manual

10.2.2 System interface terminals A and B

Simultaneous use of 4 mm cables and the system interfaces is not recommended!
15-pin system interfaces A and B function in the digital mode only, therefore the toggle switch must be
switched from the relay to the digital output function. When the toggle switch is in the upper switch
position, the 24 V LED lights up. In this case, 24 V DC is applied to the top row of output connections
(connected with the red line). This is also indicated by an LED in this section of the panel. Each output is
decoupled with diodes. In the lower switch position, voltage is enabled at terminals A and B.
Warning!
Only 24 V DC control signals with max. 500 mA can be connected.
