How safe do you need to be?

Written by Andy Maskell, Product Manager- Safety & Networks

Earlier this year the new PSRmodular safety system was launched. Since then the benefits of this new platform have been realised and implemented into a wide range of applications. Every time I get involved with a new application I learn more about how flexible this system can be and how important it has been to simplify making machines safe.

You can choose from two expandable controllers depending on the complexity of your application. Then, if required, you can decide on the expansion modules you need. There are plenty of I/O expansion modules to choose from in various sizes to suit your application, so you only order what you need.

All common input types are catered for :

  • Emergency stop
  • Two handed control
  • Safety light curtains (AOPD)
  • OSSD (Output Signal Switching Device)
  • Safety Mats
  • Zero speed monitoring
  • Over/Under speed
  • Safe analogue monitoring

The new PSRmodular software is intuitive and easy to use with pre-configured function blocks and built in monitoring for all of your safety tasks.

Current approvals:

  • Up to PLe/SILCL 3 (IEC 62061)
  • Lift application (EN81-20/EN81-50)
  • UL 508
  • Atex zone 2, CL1 Zone 2, IEC EX

One of the many special features of PSRmodular is the Line E-stop function. This feature allows the user to link multiple safety controllers together and create a global emergency stop system whilst allowing local safety functions to operate independently. If an emergency stop device is operated then all controllers will detect this and react accordingly.

If you could benefit from some remote safe I/O then we have the TBUS extension modules. The TBUS module allows the din rail mount communication connectors to be extended by cabling. Just four cores are required to do this and up to six extensions can be used per controller.

And when comes to integrating the PSRmodular system into the rest of the machine we have that covered to with the optional communication gateway options. All popular communication protocols are catered for with non-safe bidirectional communication possible for all types.

The PSRmodular Software is “FREE” and can be downloaded from our website now.

We also have various support tools to get you started on your safety journey, quick start videos, product overviews and data sheets.
