The DS200LDCCH1AGA system can be used in critical process safety control applications with safety integrity level (SIL3 and below) requirements, including emergency stop systems (ESD), fire and gas detection systems (FGS), combustion management systems (BMS), and large turbine compressor controls (CCS). We provide the best solutions to ensure the safety of critical industrial processes, especially in the fields of oil and gas, large-scale petrochemicals and chemicals, energy, transport, metallurgy and large-scale power plants.

DS200LDCCH1AGA The most basic TCS-900 system consists of an engineer’s station and a safety control station, which consists of a controller module, a safety input module and its terminal board, a safety output module and its terminal board, and a network communication module. The controller module, network communication module and I/O module of the system are mounted in a rack. The rack of the TCS-900 system is divided into a mainframe and an expansion/remote rack, and the mainframe and the expansion/remote rack are connected by an expansion communication module and a fibre-optic cable. The field I/O signals are connected to the I/O terminal boards matching the I/O modules, and then connected to the three sets of channels of the I/O modules through DB cables.

The DS200LDCCH1AGA system is designed with a fully triplexed, five-vote, high-reliability structure. This is specifically reflected in the safety circuit, which includes input modules, controllers, buses and output modules. Each controller and I/O module of the control station has three independent channel loops. The three channels within the input module simultaneously collect the same field signal and process the data separately
