6ES7626-1DG04-0AE3 & 6ES7626-1SB04-0AC0 Siemens SIMATIC C7 Integrated Controllers
6ES7626-1DG04-0AE3 and 6ES7626-1SB04-0AC0 belong to Siemens SIMATIC C7 series integrated compact controllers, combining S7-300 CPU, operator panel, digital and analog I/O modules into one compact unit. The C7 series integrates logic control, on-site operation and signal acquisition in a single device, removing the need to separately install PLC and HMI in control cabinets. This design saves cabinet installation space, reduces wiring workload and lowers the risk of loose communication cables on industrial sites.
6ES7626-1DG04-0AE3 is the C7-626/P DP model equipped with PROFIBUS DP interface, supporting distributed field bus connection to remote I/O, inverters and other field automation devices. It comes with built-in digital and analog I/O terminals to collect sensor signals and output control commands. The integrated operator panel supports local parameter setting, real-time data monitoring, alarm message display and manual operation, allowing operators to debug and monitor machines directly on the controller without additional touch screens.
6ES7626-1SB04-0AC0 is another variant of the C7-626 product family. It retains the integrated all-in-one hardware architecture of the C7 series, with matched CPU performance, built-in HMI and local I/O configuration, while differing in communication configuration and onboard functional parameters to satisfy different machine control requirements. Both models adopt industrial-grade hardware design, with strong resistance to vibration, temperature fluctuation and electromagnetic interference, suitable for continuous long-time operation in factory workshops, packaging machinery, textile lines and small process control applications.
These two part numbers are discontinued legacy automation spare parts. A large number of old production machines are still running with SIMATIC C7 controllers. When the original unit breaks down, replacing with the identical model can reuse the original control program and HMI screen project. There is no requirement to rewrite PLC logic or redesign the control cabinet, which greatly cuts maintenance cost and minimizes production downtime. Operators can continue using the familiar operating interface without extra training.
We supply fully tested 6ES7626-1DG04-0AE3 and 6ES7626-1SB04-0AC0 spare controllers. Before shipment, each unit undergoes complete functional testing, including CPU startup test, program download verification, HMI display and keypad inspection, I/O signal test and communication port check to ensure all functions operate normally. All products carry a 12-month warranty. Our professional automation technical team provides remote support for wiring guidance, program backup and fault diagnosis. Fast global shipping is available for urgent equipment maintenance orders.
For automation maintenance technicians and system integrators, 6ES7626-1DG04-0AE3 and 6ES7626-1SB04-0AC0 are reliable spare solutions to keep legacy SIMATIC C7 control systems operating steadily. They extend the service life of existing production assets and avoid the high expense of full system renovation.
