Siemens 6ES7626-1DG03-0AE3 SIMATIC C7-626

The Siemens SIMATIC C7-626, part number 6ES7626-1DG03-0AE3, is a compact combined controller and operator panel unit belonging to the SIMATIC C7 product family. It integrates a programmable logic controller (PLC) based on the S7-300 CPU architecture with an operator panel (OP) into a single housing, eliminating the need for separate HMI and controller hardware. This all-in-one design is intended for space-constrained control cabinet installations where both control logic and local operator interaction are required.

The C7-626 features a built-in STN monochrome display with touch or key-based input, integrated MPI (Multi-Point Interface) communication for connection to SIMATIC networks, and onboard I/O for direct process interfacing. The unit supports STEP 7 programming software for PLC logic and ProTool or WinCC flexible for HMI configuration. It includes integrated digital inputs and outputs, a real-time clock, and retentive memory backed by a battery or capacitor, ensuring data retention during power loss. The device operates on a 24 V DC supply and conforms to standard industrial environmental ratings.

The SIMATIC C7-626 is well suited for small to medium-sized machine automation tasks in industries such as packaging, material handling, food and beverage, and general manufacturing. Its compact integrated design makes it particularly appropriate for OEM machine builders seeking to reduce panel space and wiring complexity. The combination of local visualization and control logic in one unit simplifies commissioning and reduces overall system cost for standalone machine applications.
