Relay Modules
Light barrier controlers
Light barriers belong to electro-sensitive protective equipment (ESPE) which cut off dangerous movements and initiate a safe condition when persons or objects approach to a dangerous location.
Advantages
- Increase productivity by longer cycle times without loss of safety
- No need for mechanical safety devices
- Easy implementation of muting functions
Safety gate monitoring
The electro-sensitive protective equipment BWS-S, also referred to as type 4, is not affected by a farlure within the electro-sensitive protective equipment. Our solutions for this include:
- Type-tested evaluation circuits in compliance with relevant norms
- Prewired rail-mounted modules, also with muting function
Protection of operators on machinery who have to cyclically intervene in the process (dangerous area), e.g. loading and removal of process material/products.
A typical application is the operation of presses.
