WES5120 2340-21005 on-site controller master station unit, as the core module of D20/D200 RTU (remote terminal unit), provides high-performance local logic processing, data acquisition, and communication capabilities, supporting seamless integration with SCADA master station, intelligent electronic devices (IEDs), and other control systems. High reliability scenarios such as substation automation, distribution automation, industrial process monitoring, and energy management.
Description
Processor: Embedded 32-bit RISC processor, with a clock speed of 500 MHz, supporting real-time operating system (RTOS).
Memory: 256 MB DDR3 RAM, 128 MB Flash storage, supports user program and historical data storage.
Logical operations: Supports IEC 61131-3 standard programming languages such as ladder diagram (LD) and functional block diagram (FBD), and can execute complex automation logic (such as feeder protection and capacitor bank control).
Two 10BASE-T Ethernet interfaces (RJ45), supporting industrial protocols such as Modbus TCP, Ethernet/IP, DNP3 over IP, etc.
Two RS-485 serial interfaces, supporting protocols such as Modbus RTU and IEC 60870-5-101/104.
1 USB 2.0 interface for local programming and firmware upgrades.
Network topology: Supports star and ring topologies, compatible with redundant communication architectures (requires GE redundant switches).
Communication speed: Ethernet interface supports 10 Mbps, and serial interface supports up to 115.2 kbps.
Power supply: 24V DC (± 15%), power consumption<10W, supports reverse polarity protection.
Size: 150mm x 100mm x 80mm (compliant with 3U industrial standard).
Protection level: IP20 (preventing solid foreign objects from entering).
Working temperature: -40 ° C to+85 ° C, suitable for extreme industrial environments.
Scalability: Supports the expansion of I/O modules (such as analog input and digital output) through the backplane bus, and can cascade up to 8 expansion modules.
Support real-time collection of analog quantities (such as voltage and current), digital quantities (such as switch status), and pulse quantities (such as electrical energy).
Built in data caching mechanism, supports breakpoint retransmission and data compression, ensuring that data is not lost in case of communication interruption.
Local logic control: capable of executing protection logic, sequence control, and optimization algorithms to reduce the computational load on the main station.
