/Safety relays

Safety relays are used to monitor and control machine safety functions where a reliable, standards‑compliant safe stop or access control is required. They form a central part of machine safety systems, ensuring that safety devices such as emergency stop buttons, safety interlock switches, and two‑hand control devices operate correctly and safely under all conditions.

Our product range includes IDEM Safety relays, including the VIPER series of single‑function and multi‑function safety relays. These relays support single‑ and dual‑channel safety circuits, monitored manual or automatic reset, and feedback loop monitoring. Force‑guided relay contacts and continuous fault detection enable functional safety up to PLe / Category 4 according to ISO 13849‑1 and SIL 3 according to EN 62061, depending on system architecture. Clear LED status indicators simplify commissioning, diagnostics, and maintenance.

Safety relays are widely used in applications such as emergency stop circuits, guard door monitoring, two‑hand control systems, light curtains, safety mats, and non‑contact safety sensors. The compact DIN‑rail mounting design allows easy integration into control cabinets, while optional time‑delay and expansion modules provide flexibility for more demanding applications. Our strong product expertise helps ensure that the correct safety relay is selected for each application as part of a reliable and standards‑compliant machine safety solution.
