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).

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.

. Current consumption max.
±
250 mA
➢
All signal lines, also those of external transducers, shielded
➢
Shielding connected radially to (0V)
➢
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.
