A forced-guided contact (or mechanically linked contact) ensures that if one contact welds, the other contacts cannot change state, providing a reliable feedback signal for safety monitoring.
Safety Relays Component Intelligence
Critical monitoring components for machine safety and emergency stop systems.
What are Safety Relays components?
Safety relays are designed with redundant, self-monitoring circuits to ensure that a single component failure does not lead to a loss of the safety function. They are essential for E-stop, light curtain, and gate monitoring applications where fail-safe operation is mandatory.
How to Choose Safety Relays Components
Selecting a safety relay requires matching the safety integrity level (SIL) or performance level (PL) of your system to the relay's diagnostic capabilities.
Safety Integrity Level (SIL)
Ensure the relay meets the required SIL or PL rating for your specific machine risk assessment.
Forced-Guided Contacts
Prioritize relays with mechanically linked contacts to ensure that NO and NC contacts cannot be closed simultaneously.
Input Configuration
Verify the relay supports your required input types, such as dual-channel, single-channel, or cross-circuit monitoring.
Reset Logic
Determine if your application requires manual, automatic, or monitored manual reset functionality.
Environmental Rating
Check the IP rating and operating temperature range to ensure the relay survives the intended industrial environment.
