KL9528 | AS-Interface power supply terminal 24 V DC/30 V DC, 1.25 A

The KL9528 power supply terminal generates a 30 V DC output voltage from the 24 V DC control voltage with high-frequency decoupling for the operation of an AS-Interface network. The output voltage is short-circuit proof and is limited to a current of 1.25 A. The LEDs display the input and output voltage. There is no electrical isolation between the input voltage and the output voltage. The connection to the KL6201 AS-Interface master is established via plugs.
