Modular relays with mechanically linked guided contacts
- Direct load switching and diagnostic contact – common power supply
- Indirect load switching and diagnostic contact – different voltages
Relays with guided contacts mechanically linked for application of safety up to SIL 2. As a single-channel (1oo1) system, the diagnostic function is entrusted to a safety automaton intended for fault detection before the safety function is required. No dynamic test is planned or imposed by the manufacturer. If the NO contact does not open when the relay coil is no longer supplied, the NC contact must not close in order to prevent the reboot the machine. The use of relays as a device for the realization a safety function, requires that the electrical circuit be complies with the standards in force concerning the applications of security. The NO contact of the relay must cut off the power supply to the load when the relay coil is no longer powered. With this principle, the closing fault of the NO contact is a fault while the opening fault is a dangerous fault. The system is designed with 1oo1 logic provides a T1 interval as trial evidence. It is assumed that the time to restart the system after a dangerous failure, is equal to MTTR and the time to perform the replacement of the 7S, is equal to MTR. Considering that the call frequency “of the safety function” must not exceed 1.14 years (10000 hours)
Installation tips
- It is recommended to install a protection device against surges (SPD) to protect safety devices
- It is recommended to install a protection device against overcurrent to protect the switched load
- Check that the degree of protection (IP) of the electrical cabinet in which the 7S series relay is suitable for the application.
