SIL Safety relays

Safety relays:

When a load cannot be driven directly by a safety controller, an interposing relay becomes a requirement. SIL certified safety relays are a requirement to meet the necessary Risk Reduction Factor (RRF) when switching a load ON or OFF in an IEC61508/61511 Safety Instrumented Function (SIF). SIL certified relays guarantee that the safety function is met with a suitable and known probability of failure (PFD).

  • Slim: single and dual channel in a 12.5mm enclosures;
  • Smart units with transparent line and load monitoring feature for both NE and ND applications;
  • Suitable for operation in -40 to +70°C temperature range;
  • High availability and extended T-Proof times;
  • Universal mounting: DIN-Rail, power bus and termination board;
