The maximum current drawfor each input is 0.5 A. The supply is short-circuit proof.In the event of a short-circuit, the SmartWire-DT diagnostic LED will flashand the diagnostic bit will be set in the user program. Once the short-circuitis removed, the supply voltage will be automatically switched back on.abcdea SmartWire-DT cable with external device plugb SmartWire-DT diagnostics LEDc Status LEDs of the inputsd I0 – I3 , (I, I+, I-)-inputse 0-V-24-V connectioninput MeaningI x Input signal IxI x- 0-V-supply voltage input IxI x+ 24-V-supply voltage input Ixx 0, 1, 2, 3
