Quick and easy machine safety control

13 January 2011

Leuze electronic’s new MSI100 and 200 programmable safety controllers offer quick, easy and affordable control for light curtains, safety interlocks, E-stops and so on, without the complexity of safety PLCs, expensive licenses or having to commit to one manufacturer’s safety system. The MSI 100 has 20 safe inputs (SIL 3, PLe) and can monitor up to four Category 4 outputs, independently from one another. The modular MSI 200 is expandable to 140 safety modules or 44 outputs (PLe, SIL3, Cat 4).

Design is easy and intuitive using the ‘drag and drop’ MSIsafesoft software, which uses PLCopen certified function blocks and is available free-of-charge. This software also has an automatic logic test and a built in emulator which allows the program to be simulated on a PC, indeed it enables the MSI100 & 200’s to be tested before spending any money.

The MSI100 and 200 also offer two clock outputs and in common with the expansion modules they also have LED indicators on all inputs and outputs to help in commissioning.

Supporting the safety controllers are the MSI-FB interface modules which enable the MSI100 or MSI200 to transfer diagnostic data across to a PLC over a variety of fieldbus protocols.
