Multiplex Data Acquisition Instrument


Aiming at the industrial field where the distribution of analog and digital field instrument signals is dispersed and far away from the PLC control system or IO module cabinet of DCS system, the multi-channel signal acquisition instrument adopts the power line and Fieldbus cascade network structure. The instrument signal is centralized into the multi-channel signal acquisition instrument nearby, then connected to the PLC or DCS system through field bus cascade. Compared with the traditional way of using cable to connect all analog and digital signals of field instruments to the IO module cabinet of factory PLC or DCS system, it can greatly reduce the amount of bridge and signal cable laying, reduce the amount of installation and commissioning, reduce the number of IO modules of factory PLC or DCS system, and thus greatly reduce the investment cost. It can also omit the working of cable laying, wiring and debugging, and greatly shorten the implementation cycle of the project, speed up the progress of the project. The advantage of this product is more obvious in the renovation project.
