Treotham Euchner MGB2 modular EtherCAT P/FSoE guard locking device

The Treotham MGB2 guard locking device is now available with EtherCAT P/FSoE. The MGB2 system protects safety doors and fences in machines and installations against dangerous machine movements and combines a safety switch, bolt and door-locking mechanism into a single unit. The modular design and the optional MSM submodules offer additional functions, different networking options and intelligent communication features for industry 4.0 applications.

The guard locking system features a PROFINET/PROFIsafe connection; the safety door systems for EtherCAT/FSoE connection have an established reputation in many sectors, including the automotive industry and other fields where automation is used. The guard locking system features a functional door locking system that meets safety levels up to PL e but also has the flexibility to adapt to future requirements.

The Euchner MGB2 Modular from Treotham is designed to meet individual requirements due to its modular system design. The guard locking system is designed to be versatile, by spreading the individual functions across different modules. The three main functions — bus communication, door monitoring and control and indication — are implemented in separate modules and submodules. The MBM bus module acts as the system’s ‘head’; all information from the connected modules comes together here and moves along to the control system over the designated bus system. The control system, in turn, sends its signals via the bus module to the connected system modules.

The MGB2 interlocking and locking modules monitor the door position and lock the guards; the modules feature two special slots to accommodate submodules, which feature a range of controls and indicators such as pushbuttons, selector switches, key-operated rotary switches and emergency stop buttons. If more functions are needed, adding an MCM expansion module to the system can provide capacity for up to four extra submodules.

By separating the locking module from the bus module, users can connect up to six MGB2 Modular units to a single bus module. While collecting the signals from two or three safety doors requires two or three bus nodes, only one is needed with the guard locking system. All modules can also be mounted remotely, which allows users to place the system in the most suitable location.
