The proTEC Stagebox is a safety and emergency-stop controller for stage SFX systems, providing SIL3-compliant load disconnection for both proTEC and third-party devices.
Designed for installation in dimmer cities as well as on, next to, or behind the stage, the unit fits into standard 19″ rack systems. SIL3-certified CEE load-disconnection relays ensure safe shutdown of connected SFX devices.
Within the emergency-stop chain, the Stagebox enables SIL3-compliant shutdown of proTEC and third-party equipment, with SIL3-certified 16 A, 32 A, and 63 A CEE load-disconnection versions available.
Within the proTEC safety architecture, communication between all devices is handled through the Ethernet-based proTEC Safety Protocol.
Two safety functions are available: Emergency Halt provides a short-term safe shutdown, while Emergency Stop performs a complete shutdown with mandatory restart.
The system supports DMX, ArtNet, and sACN and extends existing show-control networks with the proTEC safety architecture. An integrated node function allows seamless network integration.
A device overview displays all connected proTEC units with status, fixture ID, PTSC (proTEC Safety Channel), and diagnostic error codes, accessible locally or via the integrated web server.
The system can be expanded with additional proTEC Controllers, Flexline Controllers, Stageboxes, and Powerguard modules. This allows SIL3-certified load disconnection up to 63 A CEE, additional Emergency Halt and Emergency Stop points, installation in 19″ rack systems or truss-mounted variants, and the assignment of multiple device groups that can be switched independently via dedicated emergency-stop functions.
