2.6.1 Sensor supply concepts
This valve offers 3 alternative concepts to supply the sensor(s) with power. This depends on the sensor type and valve
version that is used. This valve is available with an optional sensor power supply module (SPS) that converts ±15 VDC
from the 24 VDC.
Valve versions:
• 650 . . - . . G . - . . . . and 650 . . - . . H . - . . . . SPS module not included
• 650 . . - . . A . - . . . . and 650 . . - . . C . - . . . . SPS module included
Note: The SPS module can be retrofitted. Refer to chapter «5.2.2 Retrofit / replacement procedure» for instruction.
Concepts:
• External + 24 VDC supplied to POWER connector is feed through to SENSOR connector to supply 24 VDC
sensors. Refer to chapter «2.6.2 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 «2.6.3 Power and sensor connection (±15 VDC sensors) without optional SPS module»
for schematic and correct wiring.
• External + 24 VDC supplied to POWER connector is converted into ±15 VDC by the valve internal SPS and
supplied to SENSOR connector to supply ±15 VDC sensors. Refer to chapter «2.6.4 Power and sensor
connection (±15 VDC sensors) with optional SPS module» for schematic and correct wiring.
