Safety relays can be used in a variety of ways. They perform monitoring tasks in safety applications in combination with different non-contact guards. They are capable of evaluating signals from safety light grids, safety light curtains, position sensors with and without cross-fault monitoring, electronic safety sensors or mechanical safety switches for protective guard contacts.
Safety relays with relay outputs and muting function are used for the connection of safety light curtains and safety light grids. In handling and loading stations, the muting function reliably differentiates between the entry of personnel and material.
Standstill monitors and speed monitors are pulse evaluation systems for safe detection of underspeed or standstill or for safety-related minimum speed monitoring.
