Command Signal Current Floating,
Ordering Code X or E
The spool position is proportional to I

.
For a command signal I
4
= 20 mA input the spool moves
100 % P → A and B → T.
For a command signal I
4
= 12 mA input the spool is in the
defined center position.
Command Signal Voltage Floating,
Ordering Code A, D, M or T
The spool position is proportional to U
4
− U
5
.
For a command signal U
4
− U
5
= +10 V the spool moves
100 % P → A and B → T.
For a command signal U
4
− U
5
= 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 or
-10 to +10 V, Ordering Code A or T
The signal can be used for monitoring and fault detection
purposes. The spool position is proportional to Uout. The
spool position corresponds to 2 to 10 or -10 to +10 V . At
6 V ( 0 V for A or T) the spool is in center position.
10 V corresponds to 100 % valve opening P → A and B → T.
A cable fault is detected by Uout = 0 V for order code D.
