Machine guarding interlock range gets smarter

22 September 2020

Euchner has added new Modular and Classic variants to its Multifunctional Gate Box (MGB), range, which was created to provide a totally integrated locking & handle solution.

The MGB2 Modular and MGB2 Classic offer more variations, additional functions, different networking options and intelligent communication features, including diagnostic data, to help reduce equipment downtime and increase productivity. 

The MGB2 offers a combination of a safety switch, bolt, escape release and door locking mechanism rolled into one. Some production processes need an integrated emergency stop to safely stop the processes, while others need additional request and acknowledgement buttons fitted directly onto the safety door.  The MGB2 Modular and Classic solutions can be adapted to meet individual requirements for integrated operator controls and indication.

MGB2 Modular uses PROFINET PROFIsafe to communicate all the safety, non-safety and diagnostic signals to the main controller. It also includes a built-in web-server to allow straightforward interrogation of the unit without having to have specialist software or programming knowledge. The locking modules can be equipped with controls such as pushbuttons, selector switches, key-operated rotary switches or emergency stop buttons as needed. Submodules allow up to six different control elements in the locking module, which can be replaced with the minimum of disruption due to their hot-pluggable features. 

Only one fieldbus module is required for up to six locking modules. Besides fewer devices, the user also requires less on-machine cabling and PLC I/Os. If space is limited, the bus node can be installed remotely in another suitable location.

The MGB2 Classic is hard-wired directly to the relevant control system – making it a good solution for non-networked installations.
