4.3.2 Power and 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.
Concepts:
•
External +24 VDC supplied to POWER connector is feedthrough 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 feedthrough 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.
•
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 «Power and sensor
connection (±15 VDC sensors) with optional SPS module» for schematic and correct wiring.
This concept is only possible when SPS retrofit is installed.
Valve versions:
•
653. . - . . G . - . . . . and 653 . . - . . H . - . . . . SPS module not included
•
653 . . - . . A . - . . . . and 653 . . - . . C . - . . . . SPS module included
The SPS module can be retrofitted. Refer to chapter «Retrofit / replacement
procedure» for instruction.
