Emerson Control Wave 396879-11-0 CPU Module
Description
The Emerson Control Wave 396879-11-0 CPU Module is a specialized processing component for industrial control systems, with comparable technical attributes to the related ControlWave Micro hybrid RTU/PLC controller. It integrates programmable logic controller (PLC) and remote terminal unit (RTU) functionality, making it suitable for applications in oil and gas, water and wastewater treatment, and general industrial control. Powered by an ARM-based 32-bit ARM9TDMI RISC processor, it delivers high performance with low power consumption. Key hardware specifications include 1MB of battery-backed static RAM (SRAM), 4MB of synchronous dynamic RAM (SDRAM), 512kB boot/downloader FLASH, and 8MB or 16MB simultaneous read/write FLASH. The module supports multiple communication interfaces: two RS-232 ports, one RS-485 port, and an optional 10/100baseT Ethernet port, with support for up to two 10/100Mbps Ethernet ports and up to 11 serial ports (with optional built-in modem) when paired with compatible base hardware. It operates in a wide temperature range of -40 to 70 degrees Celsius, features a security key lock to prevent unauthorized access, and supports IEC 61131-3 programming and ACCOL III process control function blocks, with open standards for programming, network configuration, and communication. It is compatible with 3-slot, 4-slot, and 8-slot base units, plus 2-slot, 4-slot, and 8-slot I/O expansion bases, enabling flexible system scaling for small to mid-sized RTU applications.
