Safety interlock modules suit wider range of PLCs

21st February 2013


Fortress Interlocks is expanding its Egard range of safety interlocks with two new modules that enable customers to purchase versions to suit their sourcing or sinking current system needs.

Those customers who have a programmable logic controller (PLC) that operates sinking current can now get the new BD and BE modules from Fortress that interface with the sourcing 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 an AS-interface network.

The beauty of Egard is said to be its flexibility; modules and features can be added or removed as required. Egard combines the functionality of trapped-key interlocking with practically any combination of gate switch and/or control modules in a single versatile unit. It simply clips together and is easily installed. Its corrosion-resistant body is designed for EN 954-1 Safety Category 4, high-risk applications and complies with international standards.
