eGard and AS-i form a perfect match

MACHINERY safety specialists Fortress Interlocks have introduced an AS-interface (AS-i) control and safety base module for their eGard system, allowing eGard to be simply connected to an ‘AS-i Safety at Work’ control network in minutes. According to Fortress Interlocks, this provides significant time savings over other systems.

eGard is a modular system that can control access to hazardous machinery, via gate switch and trapped-key technology, and includes simple machine or access controls, such as push buttons, e-stops and lamps. The AS-i base has two addresses: one for connecting the safety circuits and one for connecting the control I/O. AS-i is a cable network system that allows machinery safety technology to operate in parallel with standard machine controls on a single network with a common communication protocol (Actuator Sensor Interface).

With the AS-i base module, installation of an eGard system on an AS-i network takes a matter of minutes from unpacking to commissioning. The eGard modules are simply clipped together and the AS-i cable connected. Fortress Interlocks say the extensive range of eGard modules allows the creation of an almost endless list of solutions, while the modularity makes the system extremely flexible, permitting quick addition or removal of modules (functions). Compared with hardwiring, it eliminates dual safety circuit cabling costs, provides comprehensive diagnostics and offers patented error-checking.

The AS-i base module features an LED status indicator and an AS-i standard four-pin M12 quick-connect fitting for connecting dual safety circuits and up to four inputs and outputs.
