Safe motion monitoring has become increasingly important in machine and system design.
Conventional safety technology keeps the operator away from dangerous movement by shutting down the relevant drive when a movable guard e.g safety door is opened. This usually results in the removal of power sources using contactors or other forms of power disconnection. “Safe Switch Off”.

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.

As machines become more complex, so does the safety required to protect personnel and keep machines running as they were intended. The implementation of safety should not restrict the functionality of the machine, but should enhance it. Using fixed logic safety devices greatly reduces the opportunity to do just that.

Free Workshop!
As part of Phoenix Contact’s ever increasing involvement in Machinery Safety and its growing product portfolio, we have teamed up with TUV SUD (Laidler Associates) and Mechan Controls to bring you a FREE one day workshop on Electrical and Functional Safety.
Venue: Phoenix Contact Ltd,Telford TF7 4PG
Date: 11th June 2013 9am-4pm
This one day course is to introduce and give delegates an overview of the EN 60204-1 standard as well as Safety Concept ISO13849 and Safety Concept IEC 62061. Incorporating EN ISO 14119 in order to understand the requirements and applications of electrical, electronic and programmable systems to ensure the electrical safety of machinery in industrial installations. It will give possible solutions to existing on-site problems with conformity to these standards. Through EN ISO 14119, it will identify non-compliances to the standard, showing actual machine examples and common misconceptions/assumptions of safety.

1. Risk Assessment
Phoenix Contact Safety App
Before deciding which safety input devices are required to guard your machine, it is necessary to understand which performance level you need to achieve. A risk assessment is therefore required. At Phoenix Contact we have an App which can be used on an iPhone or iPad, giving the user an interactive risk assessment guide, and therefore determining the performance level of the machine or application.
