2.6.2  Sensor supply concepts 
 
This valve offers 2 alternative concepts to supply the sensor(s) with power. This depends on the sensor type that is used. 
Optional is this valve available with an sensor power supply module (SPS) that converts 

±

15 VDC from the 24 VDC. 

 
Concepts: 

 

•

 

Ex 24 VDC supplied to POWER connector is feed through to SENSOR connector to supply 24 VDC 
sensors. Refer to chapter «Power and sensor connection (+24 VDC sensors)» for schematic and correct wiring. 

 

 

•

 External 

±

15 VDC supplied to POWER connector is feed through to SENSOR connector to supply 

±

15 VDC 

sensors. Refer to chapter «Power and sensor connection (

±

15 VDC sensors) without optional SPS module» for 

schematic and correct wiring. 

 
Valve versions:
