Command Signal Current Floating,
Ordering Code X or E
The spool position is proportional to I
D
= - I
E
.
For a command signal I
D
= 20 mA the spool moves to 100 %
P → A and B → T.
For a command signal I
D
= 12 mA the spool is in the defined
center position.
Command Signal Voltage Floating,
Ordering Code D or M
The spool position is proportional to U
D
− U
E
.
For a command signal U
D
− U
E
= +10 V the spool moves to
100 % P → A and B → T.
For a command signal U
D
− U
E
= 0 V the spool is in the
defined center position.
Actual Value 4 to 20 mA, Ordering Code M, X or E
The signal can be used for monitoring and fault detection
purposes. The spool position is proportional to I
out
. The
spool position corresponds to 4 to 20 mA. At 12 mA the
spool is in center position.
20 mA corresponds to 100 % valve opening P → A and
B → T. A cable fault is detected by I
out
= 0 mA.

Actual Value 2 to 10 V, Ordering Code D
The signal can be used for monitoring and fault detection
purposes. The spool position is proportional to U
out
. The
spool position corresponds to 2 to 10 V. At 6 V the spool is
in center position.
10 V corresponds to 100 % valve opening P → A and B → T.
