3.2 Description
The GEMÜ 4241 combi switchbox is suitable for mounting to
pneumatically operated linear actuators. The position of the
valve spindle is reliably electronically detected and fed back
via the play-free and non-positive mounting by means of a 2-
wire proximity switch (NAMUR). Integrated pilot valves enable
direct activation of the process valve connected to them.
3.3 Function
The GEMÜ 4241 combi switchbox indicates the current posi-
tion of the valve. When the valve is opened, the spindle in the
combi switchbox moves upwards and indicates that the valve
is OPEN using the communication interface. When the valve is
closed, the spring in the mounting kit presses the spindle in
the combi switchbox downwards and indicates that the valve
is CLOSED using the communication interface.
