Phoenix Contact talks to Industrial Compliance magazine about its range of machine safety solutions that are designed to offer the right solution for customers’ needs


hen designing a safe system it is important to first decide which SIL or Performance Level the machine needs to meet. Phoenix Contact has a safety App for iPhone and iPad which is free to download from the iTunes store by using the search term ‘Safety Services’. The Safety App has a useful tool to cal- culate the MTTFd value for any com- ponent in a safety circuit, which is crucial for safety calculations. Whether your requirements are for the process industry or for OEMs building machines, Phoenix Contact can provide the solution. Mark Harries, business development man-


range of flexible solutions for both centralised and distributed safety applications. Safety Bridge is well suited for applications that have a need for a distributed safe solution. The main feature of this system is that it will work with a standard non-safe PLC, over almost every protocol and using the existing bus cabling. This makes Safety Bridge an ideal solution for large machines or for retro-fit pro- jects. Phoenix Contact’s Safety Bridge is also great for users who want visual- isation of the safety I/O signals at the PLC or HMI.


SafeConf is the accompanying soft- ware for the Safety Bridge solution, and is free to download from the Phoenix Contact website. SafeConf is easy to use and allows the user to drag and drop pre-made safe function blocks to build up a suitable safe system. Useful connection diagrams, which are TUV certified, are inte- grated into the software and can be accessed at the click of the button. The SafeConf software can also be used to configure the Trisafe device, which is a configurable safety con- troller for centralised safety applica-

tions. Trisafe has 20 Safe Inputs and 4 Safe Outputs and can be expanded if required. This is a perfect solution for replacing multiple standard safety relays and therefore reducing wiring and installation time for the user. The SafeConf software for Trisafe is well suited for more com- plex safety applications where logic is required or where time delays may need to be set. This gives the cus- tomer absolute flexibility to meet the demands of their application.

New adaptor enhances machine safety


ager for safety, I/O and networks commented, “We take safety very seriously at Phoenix Contact. Our aim is to advise customers of the best and most cost effective solution to meet their requirements.”


Using the process industry as an example, Phoenix Contact has a dedi- cated range of safety relays such as the ‘FSP’ device which has an inte- grated filter to eliminate test pulses from the DCS system. This eliminates problems such as the safety relay ‘chattering’ and gives the end user peace of mind that the relay is reli- able. The ‘ETP’ safety relay can be used in fire and gas detection sys- tems for switching a range of differ- ent applications in a safe way, such as a sounder for example.


Flexibility In today’s market the need for flexibil- ity in safety applications is very important. Phoenix Contact has a

locks directly to its new amGard Pro range of LOK and Stop safety gate switch interlocks. The ability to link the two enhances Fortress’ mechanical mGard range by adding a safety switch and direct solenoid control option to the mechanical mod- ule. This means there are several possible configura- tions that LOK Link provides that will enhance safety in a variety of heavy duty, industrial applications. LOK Link can connect stainless steel mGard heads to explosion-proof locks, facilitate electrical indication of bolt position, connect a head for small radius doors and join mechanical interlocks with monitored exchange boxes and solenoid controlled exchange boxes and bolt locks. Trapped key interlocking is a proven method of
