15VDC
±
3%. Ripple < 50 mV
PP
. Current consumption max.
±
250mA
➢
All signal lines, also those of external transducers, shielded
➢
Shielding connected radially to (0V), power supply side and connected to
the mating connector housing (EMC)
➢
EMC
: Meets the requirements of EN 55011/03.91 class B,
EN 50081-1/01.92, and EN 50082-2/03.95, performance criterion class A
➢

(AWG 16)
➢
Note: When making electric connections to the valve (shield, protective
grounding), appropriate measures must be taken to ensure that locally
different earth potentials do not result in excessive ground currents.

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 C) according to
the required operating direction (to be done at the mating connector).

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.
