SICK UE 43-2MF2D2 Safety Relay

The SICK UE43-2MF2D2 Safety Relay is a compact 24 V DC safety relay module that monitors two safety input channels and drives three safety outputs, making it ideal for cross‑circuit safety circuits that supervise emergency stops, safety switches, and interlocks in automated systems. It provides two safe inputs (IN: 2) and three outputs (OUT: 3) in an IP20 enclosure, designed for panel mounting and straightforward diagnostics. The UE43 family supports cross‑circuit detection and sequence monitoring to ensure safe operation, with the UE43-2MF2D2 (6024893) specification aligning with SIL 3 (IEC 61508) and PL e (EN ISO 13849) ratings, and a PFH of about 3.0 x 10^-8 h^-1 alongside a mission time of 20 years; EN 60204-1 stop category is 0. In terms of endurance, the datasheet lists different switching cycles depending on load, including up to 1.26 x 10^6 cycles for AC‑15 at 230 V, 1.5 A, up to 5.9 x 10^6 cycles for AC‑15 at 230 V, 0.75 A, and up to 1 x 10^7 cycles for DC‑13 at 24 V with lower current, reflecting its versatility across mechanical safety applications.
