Input / proximity switches (external initiator: S4 in):
Power supply: via the büS/CANopen power supply - 10%
Current carrying capacity sensor
supply: max. 30 mA
Short-circuit protection
Design: DC 2- and 3-wire,
Normally open contact, PNP output
Input current 1 signal: I
Sensor
> 6.5 mA, limited internally to 10 mA
Input voltage 1 signal: U
Sensor
> 10 V
Input current 0 signal: I
Sensor
<4mA
Input voltage 0 signal: U
Sensor
<5V
Inputs (from master perspective) / binary or analogue feedback signals:
The recovery of the 3 valve positions reported back in binary format or the analogue position signal is
described in chapter “20PositionMeasuringSystem”onpage129.
Theanaloguetargetpositionsignal(resolution:0.1mm)is available in the büS/CANopen network as an
acyclic value / parameter.
Outputs (from master perspective) / solenoid valves:
Typ. switching capacity: 0 .9W(persolenoidvalve,for200msafterthepowerhasbeenswitchedon)
typ. continuous output: 0.6W(persolenoidvalve,from200msafterthepowerhasbeenswitchedon)
Output reduction: via the büS/CANopen interface - electronics integrated
