More Information

Overview Manuals Key Panel I/O Layout Memory Card Panel Mount

Features:

  • Combines CPU, operator panel, and mixed process I/O in one enclosure.
  • Uses a 61-key membrane interface for local operator commands.
  • Provides onboard PROFIBUS DP capability for distributed communication.
The C7-635 Key places control execution and operator visualization behind one panel cutout, reducing the number of separately mounted components.

Its integrated I/O serves directly connected field signals, while the DP interface extends the project to configured distributed stations.

A Micro Memory Card stores the controller project and is a required part of the completed operating configuration.

The Siemens 6ES7635-2EC02-0AE3 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).
Siemens 6ES7635-2EC02-0AE3 C7-635 Key Control Unit Manuals,Datasheets,Link 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 through the membrane keyboard

  • Key field: Sixty-one membrane keys provide the local command surface.
  • Function assignment: Screen functions and operator actions are assigned in the panel project.
  • Tactile operation: Commands are entered through fixed keys rather than a touch-sensitive display.
  • Panel feedback: The OP component presents process values and messages associated with the selected screen.

Bringing local signals into the controller

  • Digital input path: Twenty-four onboard inputs deliver binary field states to the CPU.
  • Digital output path: Sixteen outputs return programmed switching commands to connected loads.
  • Analog acquisition: Five analog inputs bring measured values into the integrated controller.
  • Analog control: Two analog outputs generate configured continuous command signals.

Storing the controller configuration

  • Required medium: The C7-635 operating configuration requires a SIMATIC Micro Memory Card.
  • Project content: Program blocks and configuration data are transferred through the memory-card workflow.
  • Retentive area: The 02 version provides 64 KB for data that is configured to survive operating transitions.
  • Order boundary: The memory card is not part of the complete-unit order number.

Integrating the compact unit

  • Combined enclosure: Controller and operator functions share one panel-mounted housing.
  • Connector set: Field termination requires the separately ordered connector set.
  • Supply input: The unit is powered from a 24V DC SELV source within the permitted range.
  • Heat planning: The enclosure layout must account for the unit's documented 14W power loss.
Description
Siemens 6ES7635-2EC02-0AE3 is the keyboard-operated C7-635 compact control unit. It combines a CPU 314C-2 DP controller, an OP 170B operator component, and onboard process I/O in one panel-mounted device.

The control section of 6ES7635-2EC02-0AE3 provides 96 KB of working memory, including 64 KB of retentive memory for configured data. A Micro Memory Card is required for operation, and the connector set is ordered separately from the complete unit.

Field connections on 6ES7635-2EC02-0AE3 cover 24 digital inputs, 16 digital outputs, five analog inputs, and two analog outputs. These integrated points are paired with the CPU's PROFIBUS DP capability so local and distributed signals can be combined in the same project.

Operator commands enter 6ES7635-2EC02-0AE3 through 61 membrane keys. The Windows CE panel component presents process screens while the controller continues its cyclic program, linking visualization and control without a separate external operator terminal.

Why will Siemens 6ES7635-2EC02-0AE3 not load the controller project without an MMC?
A SIMATIC Micro Memory Card is required operating hardware for Siemens 6ES7635-2EC02-0AE3 and holds the transferred controller configuration.
How should local operator commands be assigned on Siemens 6ES7635-2EC02-0AE3?
Map the 61 membrane keys of Siemens 6ES7635-2EC02-0AE3 to the intended screen functions and verify each assignment in the OP project.
Which signals can be wired directly to Siemens 6ES7635-2EC02-0AE3?
The onboard terminals of Siemens 6ES7635-2EC02-0AE3 support 24 digital inputs, 16 digital outputs, five analog inputs, and two analog outputs.
What must be ordered separately before wiring Siemens 6ES7635-2EC02-0AE3?
Siemens 6ES7635-2EC02-0AE3 requires the specified connector set and a Micro Memory Card; neither is included in the complete-unit order number.
Can Siemens 6ES7635-2EC02-0AE3 combine local and distributed IO?
Yes. Siemens 6ES7635-2EC02-0AE3 processes its integrated channels and can exchange additional data through the CPU 314C-2 DP interface.
