Optimized for right-hand integration on 15-inch display layouts, the Beckhoff C9900-E771 provides robust tactile operator input for legacy CP6x32-00xx and CP7x32-00xx control platforms. Designed for demanding HMI environments, this industrial push-button extension complements host panels without integrated keyboards by adding physical buttons, safety-critical emergency stops, and visual feedback lamps. The unit supports dual-channel signal architecture, combining digital bus transmission (via CP-Link or USB) with direct-wire terminal connections to guarantee system interoperability and fail-safe hardware control.
| Parameter | Specification Value |
|---|---|
| Manufacturer | Beckhoff Automation |
| Model Reference | C9900-E771 |
| Device Type | Push-button extension |
| Host Panel Compatibility | CP6x32-00xx, CP7x32-00xx (15-inch displays without keyboard) |
| Mounting Location | Right side of host chassis |
| Push-Button Element | 18 x Siemens Signum square, 30 x 30 mm |
| Emergency Stop Element | 1 x Siemens Signum, direct-wire design |
| Contact Configuration | Normally-Open (NO) x 2 per button (1 x bus, 1 x physical terminal) |
| Transmission Standard | CP-Link or USB (for push-button digital signals and lamp drivers) |
| Lifecycle Phase | Service Phase (Legacy support and spare part availability) |
| Country of Origin | Germany |
| Shipping Weight | 5.00 kg (Estimated) |
| Connection Node / Port | Functional Assignment |
|---|---|
| CP-Link / USB Bus Connection | Transmits Contact 1 state of all 18 buttons and powers internal status lamps. |
| Internal Terminal Strip | Exposes Contact 2 (Normally Open) for direct electrical wiring to PLC input cards. |
| Emergency Stop Terminals | Dedicated hardwire connection block directly feeding the active-safe E-Stop contacts. |
The C9900-E771 is specifically tailored to complement the dimensional aspect ratio and screw alignments of 15-inch host housings (CP6x32 and CP7x32). While electrically compatible with USB and CP-Link variants across other chassis lines, it cannot be physically mounted to 12-inch or 19-inch panels due to frame height variances. Ensure your physical configuration aligns with the correct target display sizes prior to procurement.
Note that status lamps are powered and mapped solely through the CP-Link or USB communication line. In the event of a bus loss, lamp states will fail to update. For safety-critical status loops, the second NO hardware contact on the terminal block should be used to run a physical loopback to an isolated PLC input card, ensuring logic verification independent of the display link.
When wiring the direct-access terminal row, use a shielded control cable if routing paths are adjacent to variable frequency drives (VFDs) or three-phase power lines. Connect the cable shield to the cabinet grounding bar. This suppresses transient noise that can trigger false contact state transitions on standard 24V PLC input lines.
De-energize the host control panel and any associated 24V DC terminal power lines before physically coupling this expansion unit. Failure to fully discharge system voltage prior to interface connection risks damaging USB controller logic boards and causing terminal short-circuits.
Align the expansion bracket of the C9900-E771 with the right-hand mounting track of the host 15-inch control panel.
Secure the unit physically using the supplied mounting bolts, ensuring correct torque limits to preserve IP rating integrity.
Wire the emergency stop contact block directly into your hardwired safety-monitoring loop (e.g., safety relay or safety PLC).
Connect the internal terminal block wiring to the PLC's local digital inputs, if using secondary contact loopbacks.
Attach the internal USB or CP-Link connector cable to the designated port on the host computer board, then restore power to test lamp cycles.
