Reliable galvanic isolation: All pulse inputs are galvanically isolated from the supply voltage (PELV). In addition,
pulse inputs can be isolated from the other terminals on the control card by connecting an external 24 V DC
supply and opening switch 4. See drawing on page 65.

Ω
Accuracy of analogue output ...................................................................................... Max. error: 1.5% of full scale
Resolution on analogue output. ....................................................................................................................... 8 bit
Reliable galvanic isolation: All digital and analogue outputs are galvanically isolated from the supply voltage (PELV)
and other high-voltage terminals.
