4 POWER SUPPLY
• Nominal supply voltage 24 VDC
• Operating range 10…30 VDC
• No saving operations (program flashing or parameter storing) into permanent memory can
be done under 11,5 VDC.
• Undervoltage reset ≤ 9,5 VDC
4.1 Overvoltage Protection
• Max. 70 VDC (Stresses above this value may cause permanent damage to the module.)
• Module has a shutdown circuit which protects the module 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 reaches circa 32 V. Power feed is restored
when supply voltage drops to 30 V.
4.2 Power Consumption
• Approx. 1,8 W (+24 VDC, no external load)
• Supply Voltage (V
SUPPLY
) maximum continuous current 13 A (with full external load)
• GND current sum max 13 A
