The Merlin 4000 Press Brake Guarding System

Upgrade your press brake guarding system with the advanced Merlin 4000. With a rugged 7-inch touchscreen-based HMI Controller, this system offers step-by-step operator prompting messages.

The system operates with ISB’s MX light curtain columns, 14 mm or 22 mm detection capability, and a maximum of 10 meters of coverage. With a built-in light curtain muting using two external inputs, the Merlin 4000 is designed to ensure maximum safety during use.

Press brakes are difficult to guard, but the Merlin 4000 offers a unique solution. The system’s MERLIN concept, pioneered by ISB, can learn each flange profile while making your initial sample part and automatically create a window exactly the proper size required for each specific cycle. This opening may change from stroke to stroke automatically, completely determined by our processor, not your operator or set-up personnel.
