Our TÜV-approved SIL coupling relays for safe opening and closing enable electrical isolation of signals up to SIL 3. System downtime can be minimized with diagnostic functions such as integrated validation testing and line load monitoring. SIL 3 coupling relays with ATEX, G3 coating and temperature range up to 70°C are suitable for special applications in the process industry.
