DONJOY Valve Control TOP C-TOP-2221 Description:
Donjoy C-TOP-2211 is a new pneumatic control head, designed for valve process control, it is compatible with most PLC or DCS system
(programmable logic controller) automation system, with digital communication. Includes signal transmission, position indicator, and valve control for controlling all types of process valves. With many versions and supports PNP signal, DCS, IO-Link, AS- I BUS.
DONJOY valve control technology has a history of over 20 years in research and development and manufacturing and has been updated and iterated to the fourth generation. At the same time, a full series of valve control technologies have been formed, including valve control units, valve position feedback devices, and valve positioners:

C-TOP-2221-PNP Specification
Input: Digital PNP DC 24V
Output: Digital PNP DC 24V
C-TOP-2221-DCS Specification
Input: Digital signal DC 24V+(PNP)
Output: Digital signal NPN or PNP (The specific parameters depend on the common input)
C-TOP-2221-IO-Link Specification
I0-Link V1.1 Interface communication
C-TOP-2211-I0-link controller is a pneumatic control head mounted on the top of a pneumatic valve actuator, it is compatible with the l0-link interface master station with international standards, it includes signal transmission, LED position light Display, valve opening and closing control and other functions. The colour and position accuracy of the position LED light can also be reset through the IODD document according to the user’s working conditions or preferences. The setting method is very simple. “PC or PLC combined with 1ODD file description” can be achieved.
C-TOP-2221-AS-I Specification
Input: AS-I 3.0 interface
Output: AS-I 3.0 interface
AS-I is a kind of field bus system. It could interconnect the controller, and binary sensor (subordinate device) with the control equipment of an upper computer (master control). The connection is conducted to communicate by a flat cable which supplies power to the solenoid valve and sensor.
