Fortress Interlocks enhances eGard PLC compatibility

Fortress Interlocks Ltdvisit website

 

Fortress Interlocks has expanded its eGard range of safety interlocks with two new modules that enable customers to purchase versions to suit their current-sourcing or current-sinking system needs.

Customers with a current-sinking programmable logic controller (PLC) can now get the new BD and BE modules from Fortress that interface with the PLC input cards and operate with all standard eGard core modules. The BD module has the capability to handle two I/O and the BE modules can handle eight I/O. Both are TUV-approved.

eGard is a fully modular system that can control access to hazardous machinery via gate switch and trapped-key technology, and can also include simple machine or access controls such as pushbuttons, emergency stop switches and lamps. eGard can connect to PLCs and mimic panels or can be used on AS-interface networks.

Modules and features can be added or removed, making eGard very versatile. eGard combines the functionality of trapped-key interlocking with practically any combination of gate switch and/or control modules in one versatile unit. It simply clips together and is easily installed. Its corrosion-resistant body is designed for Safety Category 4, high-risk applications and complies with international standards.
