Control card, digital inputs:
Number of programmable digital inputs 8
Terminal nos. 16, 17, 18, 19, 27, 29, 32, 33
Voltage level 0-24 V DC (PNP positive logics)
Voltage level, logical '0' < 5 V DC
Voltage level, logical '1' >10 V DC
Maximum voltage on input 28 V DC
Input resistance, R
i
2 k
Ω
Scanning time per input 3 msec.
Reliable galvanic isolation: All digital inputs are galvanically isolated from the supply voltage (PELV). In addition, the
digital inputs can be isolated from the other terminals on the control card by connecting an external 24 V DC supply
and opening switch 4. VLT 5001-5062, 525-600 V do not meet PELV.
Control card, analogue inputs:
No. of programmable analogue voltage inputs/thermistor inputs 2

Reliable galvanic isolation: All analogue inputs are galvanically isolated from the supply voltage (PELV)* as well as
other inputs and outputs.
* VLT 5001-5062, 525-600 V do not meet PELV.
