Connections:
"Multi-pole": 1 x M16 x 1.5 cable gland / size22 with multi-pole connection
(M12plugaccordingtoIEC61076-2-101,5-pole)forDeviceNetbus
and power supply, cable length approx. 80 cm
1 x M16 x 1.5 cable gland/size19 - connection option for external
initiator(sealedwithdummyplug,removethesebeforeuse)
Power supply:    11…25VDC(accordingtospecication)
Max. power consumption:    <200mAat24VDC(200msafterswitchingonofthevalves)
Input / proximity switches (external initiator: S4 in):
Power supply: via DeviceNet power supply - 10%
Current carrying capacity sensor
supply: max. 30 mA
Short-circuit protection

Inputs (from master perspective) / binary or analog feedback signals:
The recovery of the 3 valve positions reported back in binary format or the analog position signal is
described in chapter “20PositionMeasuringSystem”onpage129.
Outputs (from master perspective) / solenoid valves:
  Typ.switchingcapacity:    0.9W(persolenoidvalve,for200msafterswitchingon)
  Typ.continuousoutput:    0.6W(persolenoidvalve,from200msafterswitchingon)
Power consumption per
solenoid valve: 50 mA at 12 V DC

13.5 Safety position if the bus fails
Ifthebusfails,thesolenoidvalveisswitchedtoaprogrammablesafetyposition(default:solenoidvalvenot
energised).Forcongurationdataseechapter“13.12.1Congurationofthesafetypositionofsolenoidvalves
duringabuserror”.
