Various CPUs provide factory-wide automation solutions

NA400PLC provides a variety of CPU models from economical to hot standby redundant, which can meet the requirements of unit monitoring system for medium and large hydropower stations.

NA200PLC provides a variety of CPU models with RS485 interface and Ethernet interface, which can meet the local control requirements of gates and auxiliary equipment. The rich communication interface is more convenient to communicate with the unit monitoring system.

Integrated RS485 multi-serial communication module

① Complete the communication protocol independently, that is, it can exchange data with the NA400 CPU through the CAN network, and can also exchange data with the external serial device through the serial port.

② 4 extended RS485 serial ports, which can support internal Modbus master station communication, and can also carry out custom protocol communication, and can communicate with debugging, excitation, and computer protection.

③ An RJ45 Ethernet interface, with NAComm software can be configured to monitor and debug.

④ Divide the input and output, which supports a maximum of 1024 switching input, 1024 switching output, 512 analog input, 512 analog output.

Professional SOE event recording module

The SOE event recording module directly receives the GPS second pulse signal for timing, and the time is more accurate. Simultaneously synchronize the time with the CPU. The SOE event is generated by the event recording module and transmitted to the CPU through communication. The internal memory of the module can record up to 2048 events to prevent time loss after communication with the CPU is interrupted.

Intuitive flowchart editing language

According to the characteristics of the sequential control of hydropower stations, our company has developed a sequential control programming language, which makes programming faster, easier to modify, and intuitive debugging, which greatly shortens the programming time of field service personnel.
