Samson 3767 - Switching Amplifier

EB8355-2EN 37
Connections
Thewiresforthereferencevariablemustbe
connected to the terminals 11 and 12 locat-
ed in the housing.
In general, it is not necessary to connect the
positionertoabondingconductor.Should
thisberequired,however,thisconductorcan
beconnectedinsidethedeviceoroutsideon
the device.
Depending on the version, the positioner is
equipped with inductive limit contacts and/
or a solenoid valve.
Versions with position transmitter do not per-
mit the connection of additional equipment.
The position transmitter is operated on a
two-wirecircuit.Theusualsupplyvoltageis
24VDC.
Taking the resistance of the supply leads into
account, the voltage at the position transmit-
terterminalscanbebetween12and
45VDC.
RefertoFig.12ortothelabelonthetermi-
nalblock.

4.2.1 Switchingamplier
The operation of the inductive limit contacts
requiresswitchingampliersinaccordance
withEN60947-5-6tobeconnectedinthe
outputcircuit.Observetherelevantregula-
tions for installation in hazardous areas.
