11 POWER SUPPLY
• Nominal supply voltage 12/24 VDC
• Operating range8,4…36 VDC
• Undervoltage reset ≤8 VDC
11.1 Overvoltage Protection
• Max. 70 V continuous (Stresses above this value may cause permanent damage to the
unit.)
• The unit has a shutdown circuit which protects the unit and loads against overvoltage. The
shutdown circuit cuts off the power feed for the logic and loads in case of overvoltage. The
shutdown circuit is activated when voltage exceeds circa 36,8 V. Power feed is restored
when supply voltage drops under 36,8 V.
11.2 Power Consumption
• Supply voltage (U
in
) maximum continuous current 6 A (with full external load)
• GND current sum max 6 A
In this unit, there is only one power supply pin (X1.23).
The ground pin (X1.22) is the recommended pin for the power supply return line. The following
table shows the power supply pin locations.

Always use an external fuse to protect the unit. The fuse is needed for reverse
voltage and overload protection. For more information, see section Power Supply
