Valve electronics with supply voltage 24 Volt and 11+PE - pole connector
a. Command input
Command signal 0 to
±10 V
The spool stroke of the valve is proportional to (U
D
– U
E
). 100% valve opening
P ➔ A and B ➔ T is achieved at (U
D
–U
E
) = +10 V. At 0 V command the spool is
in the center position.
The input stage is a differential amplifier. If only one command signal is
available, pin D or E is connected to signal ground (pin B) according to
the required operating direction (to be done at the mating connector).
Command signal 0 to
±10 mA
The spool stroke of the valve is proportional to (I
D
– I
E
). 100% valve opening P➔A
and B ➔ T is achieved at (I
D
– I
E
) = +10 mA. At 0 mA command the spool is in
the center position.
Either pin D or E is used according to the required operating direction.
The unused pin is left open (not connected at the mating connector). The
input pins D and E are inverting.
b. Monitoring output
Actual value 0 to
±10 V
Valves with voltage and current command input
The actual value, i. e. the spool position, can be measured between pins 6 and
7. This signal can be used for monitoring and fault detection purposes. The
signal can only be measured using a weighted differential amplifier (see dia-
gram below) or a voltmeter with an input impedance greater than 1M
Ω. The
spool stroke range corresponds to ±10 V. The centered position is at 0 V.
+10 V corresponds to 100% valve opening P ➔ A and B ➔ T.
If the actual value will be used with a machine control system, the differential
input circuit must be used. Another option is to use the aforementioned
circuit for the 6+PE pole connector. Pin 6 according to DIN 43 651
corresponds to pin F according to DIN 43 563 (see diagram page 12).
