4.1 general description
The cable plug booster Type 2511 consist of a polyamide body with
integrated electronics and a connector diagram in accordance with DIN
EN 175301-803 (previously DIN 43650 Form A).
The cable plug is used exclusively to control DC coils. The built-
in rectifier makes it possible to operate with DC or alternating
current.
4.2 function
The cable plug booster Type 2511 is used to increase the power
of solenoid valves. The switchable pressure range can therefore be
extended. Furthermore, the power consumption and the coil temperature,
e.g. during continuous operation, can be reduced considerably. Appro-
priate solenoid coils must be individually designed for the particular valve
and power supply. Please contact your Bürkert sales office.
The high pick-up power is generated by overexcitation. When the valve
is actuated, the electronics drop to a low holding power. The electronics
in the 24 V DC model are able to detect the switching point of the valve
and automatically change to the reduced power phase after switching,
