ABB CMA120 (3DDE300400) is a panel-mounted basic controller belonging to the ABB SYNPOL D family, engineered for direct process control and monitoring in industrial automation. It integrates a 10.4” color LCD display with a tactile keypad, digital/analog I/O, and multi-protocol communication ports into a single unit, eliminating the need for separate HMI and PLC. The controller is powered by a 32-bit processor with 256MB RAM, supporting IEC 61131-3 programming for custom logic. It communicates via 10/100Mbps Ethernet, RS-232, RS-485, and PROFIBUS DP, with protocols including Modbus RTU/TCP, ASCII, and PROFIBUS DP-V1. Designed for panel installation (287×240×200mm, 5.76kg), it is CE/UL certified and ideal for retrofitting legacy control rooms.
