Always use an external fuse to protect the control unit. The fuse is needed for reverse voltage and overload protection.
Nominal supply voltage 12/24 VDC
Operating range 8,5…33 VDC
Undervoltage reset ≤ 8 VDC
Max. 70 V (Stresses above this value may cause permanent damage to the module.)
Control 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 reaches circa 35 V. Power feed is restored when supply voltage drops to 32,5 V.
Approx. 1,5 W (+24 VDC, no external load)
Supply Voltage (Uin) maximum continuous current 13 A (with full external load)
GND current sum max 13 A

Note 1: Load dump protection according to ISO7637-2: 2004 pulse 5, Us=+123 V. For more information, see EMC Tests
Note 2: If the voltage is less than 8,5 V or higher than 33 V, the control unit is in non-operational state.
