C-TOP+ AS-i Control Unit

The C-TOP+ control unit with AS-i (Actuator Sensor Interface) communication is designed or intended for the optimal automation of INOXPA process valves. This option is available for the entire range of valves supplied with C-TOP+ units (ball valve, butterfly valve, single and double seat multiway valve, etc.)

The AS-i interface is a field bus system that allows connecting a network of actuators and sensors (detectors) to a higher level control device (master).

An AS-i network comprises the following elements: a power supply, one or several master (or control) modules, bus cable (preformed cable); an IDC connector, an IDC connector to C-TOP+ connector connection cable, and the C-TOP+ prepared for AS-i (special card for AS-i with connector).

The AS-i field bus obtains the required voltage from a power supply. The sensors and solenoid valves connected to the field bus are controlled by the master module. Every master sends the information to the PLC and is able to control up to 62 slave units (62 C-TOP+ AS-i units).

The C-TOP+ AS-i also incorporates three signalling LEDs which continuously indicate the status of the valve, and one flashing red LED to alert in case of signal loss.

Technical informations

Features:

The C-TOP+ AS-i is characterised by its modular simple and robust design which guarantees maximum flexibility during installation. Due to its enormously reduced wiring requirements, it facilitates the installation and commissioning of the system. Moreover, it reduces the commissioning time and potential installation errors.  

The C-TOP+ AS-i heads are configured according to each customer's requirements.
