KL9528 - AS-i Power Supply Terminal

The KL9528 power supply terminal generates a 30 V_DC output voltage from the 24 V_DC control voltage for operating an AS-i network. The output voltage is high-frequency decoupled, short-circuit-proof and limited to a current of 1.3 A. There is no electrical isolation between the input voltage and the output voltage.

The connection to the KL6211 AS-i master terminal is established by the power contacts during side-by-side plugging.

The KL6201 AS-i master terminal must be connected via cable bridges.

LED	Meaning
AS-i power (green)	off	AS-i voltage is switched off.
AS-i power (green)	on	AS-i voltage is switched on.
Error (red)	off	KL9528 OK
Error (red)	on	An error (e.g. undervoltage, overload) has occurred.

	Mapping of the KL6201 and KL9528 Please note the following for addressing (mapping) of the KL6201 and KL9528: - The KL6201 AS-i master terminal is a byte-oriented terminal! - The KL9528 AS-i power supply terminal is a byte-orientated terminal. The Bus Terminals are always mapped in the following order in the Bus Coupler: First, all byte-oriented Bus Terminals appear in the process image in the order they were connected. Then, all bit-oriented Bus Terminals appear in the process image in the order they were connected. This means that the KL6201 and KL9528 do not necessarily follow each other in the process image, even if they are connected side by side!

Input data

Bit	Value	Name	Meaning
1 and 0	00_bin	OK	No error
	01_bin	Overload	Due to an AS-i overload, the KL9528 has switched off the voltage. It can be switched on again with a leading edge of output bit 0. If the overload is still present, the KL9528 is switched off again.
	10_bin	reserved	-
	11_bin	Under- voltage	The KL9528 has switched off the AS-i voltage, because the input voltage had fallen below 21 V. As soon as the input voltage rises above 21 V, the KL9526 automatically switches the AS-i voltage back on.

Output data

Bit	Meaning
0	After a switch-off due to overload, a rising edge of this bit switches the AS-i voltage back on.
1	reserved
