Designed for seamless integration on the right side of Beckhoff CP6xxx and CP7xxx Control Panels and Panel PCs, the C9900-E875 push-button extension provides a rugged, tactile physical operator interface for 15-inch displays without keyboards. This industrial-grade extension interface bridges physical emergency stop and operational commands directly into the automation control system, enhancing both safety and operator efficiency on the plant floor.
| Parameter | Specification |
|---|---|
| Manufacturer | Beckhoff Automation |
| Model Number | C9900-E875 |
| Compatible Series | CP6x32-00xx & CP7x32-00xx (15-inch without keyboard) |
| Mounting Location | Right side of Control Panel / Panel PC |
| Push-Button Type | 18 x Siemens Signum square (30 x 30 mm) |
| Emergency Stop Button | 1 x Siemens Signum, direct-wired safety channel |
| Signal Transmission | CP-Link or USB (Digital signal for 1st NO contact) |
| Parallel Hardwiring | Terminal row interface for 2nd NO contact |
| Signal Lamp Control | Exclusively via CP-Link or USB communication |
| Status Phase | Service phase (Legacy spare part support) |
| Shipping Weight (Calculated) | 5.0 kg |
As this module is in the official Beckhoff service phase, ensure your target Panel PC or Control Panel has the necessary firmware revision to detect the internal USB/CP-Link controller. Older CP6x32 architectures may require legacy Windows driver profiles to correctly map all 18 push-button indicators.
When active, simultaneous illumination of all 18 signal lamps can load the internal power distribution circuit of the panel HMI. To prevent communication drops over USB, use a high-quality shielded USB connection, or power the host Control Panel through an isolated 24V DC source to avoid ground loop current loops feeding into the signal line.
Always wire the emergency stop button using the direct-wired contact terminal block straight into your safety relay or fail-safe PLC (such as TwinSAFE), rather than relying on the CP-Link/USB fieldbus signal. This satisfies Cat 4 / PL e safety circuit requirements by maintaining hardware-level independence from the HMI OS execution loop.
CRITICAL SAFETY WARNING
Before mounting or wiring the C9900-E875 extension, verify that the host Control Panel and all associated power supplies are fully de-energized. Failure to disconnect physical power can damage the internal CP-Link/USB communication transceiver and cause unexpected safety circuit activations.
