Description
The GEMÜ 1441 cPos-X is an intelligent, digital electro-pneumatic positioner in 2-wire technology used to control pneumatically
operated process valves. It can be combined with single acting or double acting linear actuators or quarter turn actuators. This
means that it can be used, among other things, for diaphragm, globe and diaphragm globe valves as well as for ball valves and
butterfly valves, for instance. The positioner has a robust housing with a covered LCD display for status information. The posi-
tioner can be operated remotely using a mobile device in order to configure settings and to view detailed information.

GEMÜ CONEXO
The interaction of valve components that are equipped with RFID chips and an associated IT infrastructure actively increase
process reliability.
Thanks to serialization, every valve and every relevant valve component such as the body, actuator or diaphragm, and even auto-
mation components, can be clearly traced and read using the CONEXO pen RFID reader. The CONEXO app, which can be in-
stalled on mobile devices, not only facilitates and improves the "installation qualification" process, but also makes the mainten-
ance process much more transparent and easier to document. The app actively guides the maintenance technician through the
maintenance schedule and directly provides him with all the information assigned to the valve, such as test reports, testing doc-
umentation and maintenance histories. The CONEXO portal acts as a central element, helping to collect, manage and process
all data.

Ordering
GEMÜ Conexo must be ordered separately with the ordering option "CONEXO".

Order data
The order data provide an overview of standard configurations.
Please check the availability before ordering. Other configurations available on request.
Note: Pneumatic connecting components (union and compressed air tube) for the connection between the process valve and
positioner are included with each positioner.
Note: A valve specific mounting kit is required for assembly. For designing the mounting kit, the valve type, nominal size, control

During initialization, the 1441 cPos-X positioner automatically detects the control function of the
valve and is adjusted by default so that the valve is closed when the signal is 4 mA*.
The assignment can subsequently be changed using parameters. The close-tight function that is in-
tegrated as standard ensures that the valve is moved completely to the end position when the sig-
nal Open or Close valve is given.
