Features:
- Combines CPU 314C-2 DP control and OP170B operation in one panel unit.
- Provides integrated digital, analog, and technology I/O channels.
- Uses a 61-key membrane keyboard for local operator input.
The C7-635 Key reduces the control and operating sections to one enclosure while keeping the CPU and operator-project storage functions distinct.
Directly integrated process channels handle the base signal set, and additional S7-300 I/O can be attached through the documented expansion arrangement.
The front-panel gasket and mounting supports establish the IP65 operator side when the specified control-cabinet cutout is prepared.
The Siemens 6ES7635-2EC01-0AE3 C7-635 Key Compact Control Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Operating the local interface
- Keyboard: A 61-key membrane matrix provides local entries.
- Operator section: The OP170B functions run on the integrated Windows CE platform.
- Project controls: Configured screens and key assignments determine the operator workflow.
- Panel boundary: The keyboard belongs to the Key version rather than the C7-635 Touch arrangement.
Connecting the base process signals
- Digital acquisition: Twenty-four inputs receive binary process states.
- Digital commands: Sixteen outputs provide the integrated discrete control points.
- Analog measurement: Five inputs accept configured analog signals.
- Analog commands: Two outputs carry the integrated analog control values.
Separating CPU and operator storage
- CPU program: A SIMATIC Micro Memory Card is required to run the CPU user program.
- Panel project: The operator configuration is managed independently of the CPU program.
- CF expansion: A CompactFlash card supports larger recipe storage or panel replacement without a PG/PC.
- Media check: The required card type must be matched to the CPU or operator section before loading data.
Establishing the cabinet interface
- Cutout: The C7-635 Key fits a 231×257 mm opening with +1 mm tolerance.
- Supports: Ten mounting supports secure the Key unit from the rear.
- Front seal: Even gasket compression preserves the documented IP65 front boundary.
- Rear access: The rear enclosure and terminals remain within the IP20 side of the installation.
