Inoxpa C-TOP eX Control Unit


The C-TOP eX Control Unit is designed to automate pneumatically operated process valves in potentially explosive environments. This control unit fits every INOXPA actuator and is widely used in industries such as food, beverage, chemical and pharmaceutical processing. By integrating valve control and position feedback into one compact solution, the C-TOP eX ensures reliable and efficient valve automation in demanding production environments.


Application of the C-TOP eX Control Unit

The C-TOP eX control unit is specifically developed for installations where process safety and automation are essential. It is mounted directly on top of the valve actuator and enables automated control of pneumatically operated valves in areas with explosion risk. Thanks to its robust design and compatibility with INOXPA actuators, the unit can be easily integrated into process installations within food, beverage, chemical and pharmaceutical industries.

Operating Principle of the C-TOP eX

The control head is equipped with a sensor system that provides NAMUR feedback through an LED indicator and low voltage solenoid valves. These components are suitable for connection to an electrical or intrinsic safety barrier and can be linked to a PLC via a digital interface. External signals activate one to three solenoid valves that operate the valve actuator, while inductive sensors monitor the position of the actuator using a metal target mounted on the actuator shaft.

Design and Key Features
The C-TOP eX is designed for simple installation and reliable operation in automated process systems. Key features include:

  • Easy installation directly on top of the valve actuator
  • Quick and straightforward configuration
  • Position detection through NAMUR inductive sensors
  • LED indicator for visual verification of sensor detection status
These features ensure accurate valve position monitoring and seamless communication with the control system, allowing process installations to operate safely and efficiently.
