About us: Beijing Tengcontrol Technology Limited Company

Rely on the hardware, software and network technique, Tengcon Technology devoted to manufacture industrial automation core products and systems with more than 30%of employee are focus in Research & Development. Tengcon has deep and wide experience in various signal acquisition, especially on electric signal acquisition, and also, familiars with all main protocol like MODBUS, IEC8705, PROFIBUS DP, CAN, PROFINET etc., and knows the ropes of IEC61131 and technology of Programmable Logic Controller development as well as IEEE1588 and Clock Synchronization Technology in Ethernet, we are also robust on antiinterference and lightning protection technology to ensure the reliability of every product delivered to customer.

Tengcon Technology proposed a new advanced concept of Complete Distributed Network Control System, in that the control system is constructed via absolutely new theory. It can be applied to construct the SCADA (Supervisory Control and Data Acquisition), PLC (Programmable Logic Controller) and DCS (Distributed Control System). Typical product were developed based on these is T9 series which were launched in market already. More than 100 thousands of product have been delivered to customers and got widely and good customer acceptance in past years. 

All these products are being used in various industries in 18 counties. They showed strong reliability in different systems and wide environment include High Speed Rail, oil and gas field, power monitor and control system, kind of automatic production line, Building Management System,city lighting control system, vehicle monitoring, agricultural farms etc. we are keeping to develop and provide first class of product to all the customer in worldwide.
