For sale is a Siemens SIMATIC C7-621 industrial controller, a compact and integrated solution combining a programmable logic controller (PLC) and an operator panel (HMI) in a single device. This model features a built-in LCD display screen with a blue border, accompanied by arrow navigation keys surrounding the screen, and a numeric keypad with function keys F1 to F5. The control panel includes a green ENTER button and grey ESC and SHIFT buttons, facilitating user interaction and programming.
The device supports communication and programming via the MPI interface and is compatible with Siemens STEP 7 and ProTool software for programming and configuration. It offers a versatile range of inputs and outputs, including 16 digital inputs and 16 digital outputs operating at 24V DC, 4 analog inputs for voltage or current signals, and 1 analog output.
The controller is designed for machine control, production lines, and automation tasks, and it can be expanded with additional modules to suit specific application needs. The metal frame and mounting clips provide sturdy support, while ventilation slots on the metal casing help with heat dissipation during operation.
The unit's plastic casing shows slight yellowing and minor surface wear consistent with age and use, along with some minor dirt marks. Green terminal connectors with red locking tabs are present on the side, ensuring secure wiring connections. The rear of the device includes two serial DB9 connectors and a green power or signal connector. A screw secures the metal plate on the back, with slight wear visible.
This Siemens SIMATIC C7-621 controller is a reliable industrial platform suitable for retrofitting and equipment modernization projects. Please note that no specific information about the year of manufacture or operational testing status is provided.
